Desistance Rehabilitation And Reintegration

Desistance Rehabilitation And Reintegration When a criminal is able to stop the behavior that characterizes his or her criminal activities, the gradual process involved is what is termed as desistance. Apart from the fact that it has practical applications for probation workers with criminal offenders from the community, desistance also has a strong link and connection in the rehabilitation of a criminal. However, theories of desistance when compared to the theories of the onset of criminal behavior have been much neglected and underdeveloped in the history of criminology (Smith, 2007). It is therefore a good sign when studies of desistance increase drastically especially since the last twenty years; this has been particularly noticeable after the development of the life course theory that was done by Sampson and Laub. But as Piquero (2004:103) explains, continued research has been significantly affected by methodological and theoretical issues. Moreover, theorists in the field have not been able to come up with a universal de finition of desistance. Consequently this paper endeavors to create a workable definition of desistance and to furthermore give a preview of the updated main facts and theories of desistance. Understanding desistance Oxford Dictionary defines desistance as, to desist or to stop doing something; cease or abstain. Applying this definition to criminology is however a bit technical. The big question is usually about time, if a criminal is able to stop a certain criminal behavior for four weeks for example, is it correct to classify him or her as an accomplished case of desistance? What is the recommended time for one to be sure that he or she is free from the crime? If future behavior can best be predicted by looking at past behavior, and if recidivism and relapse are the rule rather than the exception, then how does a precise definition of desistance be formulated? (LeBel et al, 2004). Laub and Sampson (2001) as a matter of fact agree that a definition of desistance cannot be made, they support that the questions in a particular research best deduce the definition of desistance for the researcher (cited in Maruna, 2006). According to Shadd Maruna, for a habitual offender, any recognizable time spent without doing any crime is called primary desistance. However studies on recidivism and relapse cannot be complete without an outline of achieving long term desistance. Maruna goes on to therefore state that secondary desistance is when a criminal is able to change his identity and take an almost permanent direction to a life free of the initial crime that was a norm in his behavior. Studying secondary desistance is important as it seeks to understand how initial offenders can be able to keep a distance from their crimes. Desistance is therefore not the final result of the end of a crime; it is actually the process that is gradual and continuous till the end result of successful desistance. Sampson and Laub (2001) acknowledge that there is a huge difference between the stopping an offence and the continuous change to a crime free lifestyle. They mark that as compared to theories of offending, desistance theories have not yet been fully studied and explained, however desistance is now understood as the procedure necessary for acquiring a n accomplished state of non-offence. It is important that a criminal who wants to change must be willing to change his or her self identity and concept to be able to grasp the full context of change. Gottfredson and Hirschi (1990) explain that on the contrary it is a common occurrence to find ex-offenders who have undergone desistance commit other acts of deviance, (cited in Sampson and Laub, 2003: 298). Desistance is therefore basically the ability of a former criminal to be able to completely withdraw from a crime and to maintain being in that state regardless of the challenges involved when trying to keep away. Some of these challenges are social stigma, return to criminogenic environments after release from prison, homelessness, addiction, and limited career and educational opportunities (Richards and Jones, 2004). Career criminals are those who have been criminal offenders for a considerably long period of time (Maruna, 2001). According to Laub and Sampson (2003), career criminals rather than small time offenders should be given more attention in researches on desistance. However another major problem in the study of desistance is the availability of completely successful offenders in desistance to the researchers in the field (Maruna, 2001; Burnett, 2004). Total desistance to many ex-offenders is quite a hard step as most of them usually end up going back to their initial criminal tendencies (Piquero, 2004). Addiction is a very significant factor that is more often overlooked yet its contribution to the whole process of desistance has a major impact on the ability of a criminal to completely change. It is therefore important to understand the connection between the two before arriving at a definition of desistance. From a number of researches it has been recognized that the link between addiction and criminal activities is actually very strong. A drug addict is therefore more likely to engage in crimes (Maruna, 2001). Moreover the cause of addiction and criminality are as a matter of fact very similar. Frisher and Beckett (2006:141) found that a large percentage of drug abusers are very active members in criminal gangs. Therefore, when defining desistance, it is necessary to note that the complete resistance of both criminal offending and drug abuse must be realized (Maruna, 2001). To achieve the purpose of this paper desistance can be described and defined as the initial process allowing quality desistance from drug abuse, criminality and other forms of deviance for an ex- criminal. Quality desistance in this case is the is the total termination of previous criminal behaviors together with other possible forms of deviance like drug abuse for at least ten years accompanied by a change in the identity of an individual. Desistance theories Ageing Age has been found to be a significant factor in criminology, as one grows older it is noted that their level of criminality greatly reduces. (Smith, 2007; Sampson and Laub, 2003; Gluecks, 1943; cited in Sampson and Laub, 2003; Gottfredson and Hirschi, 1990; cited in Sampson and Laub, 2003). In 2000 in the United Kingdom 19 year olds were found to have committed crimes fifty times more those which men of over fifty years had committed. According to research the total lifespan of a criminal is usually general considering factors like early deaths, imprisonment and when a criminal is evolving to avoid being detected (Maruna, 2006). In a research of 411 criminal males in London, Farrington (1990) found that as the criminals grew older, their crimes reduced greatly with time but this however depended on different types of crimes (cited in Smith, 2007). For example, burglary is at its highest at age 20 while fraud and drug abuse offences record their highest at the age of 25 all the way to 30 as burglary sets on a steady decline afterwards. Nevertheless for the persistent hardcore criminals into their 70s, there was a clear connection between their age and their crime rates according to studies by Laub and Sampson (2003, 2005, 2005b). Furthermore they realized that alcohol and drug offences were their highest in the mid- thirties as compared to other offences. They finally came to a conclusion that both age and the type of crimes affect the whole process of desistance as well. However there have been different explanations to the not clear age crime curve. Developmental criminologists have been able to link the ag e of an offender and the capability of total desistance to childhood related issues. (Mulver et al, 1988; cited in Sampson and Laub, 2003; Nagin, 2005; cited in Sampson and Laub, 2005a) Offenders are therefore divided into two distinct groups, the adolescent and the persistent adult offenders. As a result it will be evident that in their late teens the adolescents will be able to grown out of crime and will be able to work on their social circles basically due to their education and good social integration skills. Academic failure, broken relationships and neuropsychological handicaps on the other hand doom the adult offender to a life of deviancy (Moffitt, 1993; 1994; cited in Sampson and Laub, 2003). This theory therefore separates offenders into two distinct groups each with very unique characteristics determined by childhood factors, and only those who fall into the correct group have any hope of desistance. Sampson and Laub (2003; 2005a; 2005b) have strongly criticized this developmental approach to explaining desistance, and state that, there is no such thing as a fore-told life course persister (2003:179). They explain that desistance is achievable for ant type of offender no matter which group they are in whether adolescent or adults. According to them childhood fa ctors of offence do not determine desistance but instead help to explain the whole process of desistance. Gottfredson and Hirschi claim that offenders simply stop offending because of the natural aging of the individual (1995; cited in Sampson and Laub, 2003). They point out that for any organism there is always a stage of discontinuity that applies to criminology and the study of desistance and its links with age. Therefore desistance is a natural process for any offender. Maruna (2001) however does not fully agree with this because according to him desistance, especially at the beginning, takes a huge amount of emotional, psychological and even physical effort and resources. Gluecks (1943) agrees with this too because he highlighted that desistance was the result of a process of maturational reform, meaning, an offender gradually grows out of crime (cited in Sampson and Laub, 2003). This maturation process usually starts after age 25 when a criminal is able to settle down as the crime rate reduces gradually. However this theory has similarly been criticized as it does not probe into th e meaning of age; instead it assumes that the process of aging itself is responsible for desistance (Maruna, 2001; Sampson and Laub, 2003). Acknowledging that age is a significant factor in desistance, Sampson and Laub (1992) state that maturational reform does not satisfactorily explore its significance in relation to social bonds and life turning points (cited in Maruna, 2001). Life Course Theory A significant study on 500 men up to the age of 32 was carried in the 1930s and 1940s by the Gluecks (1943; cited in Sampson and Laub, 2003; 2005a; 2005b). Sampson and Laub later on in an impressive research followed up on 52 of these men and investigated on their criminal career to the age of 70. They found out that the causes of desistance and persistence are actually opposites, namely the development of social controls, structured routine activities and purposeful productive human agency (Sampson and Laub, 2003; 2005a; 2005b; 2006). Their finding indicated that job stability, military service and marriage were able to positively contribute to achieving desistance. These turning points were realized in the process of desistance whereby an offender seeks to start a new life by changing location or even starting a new job like entering the military for example. This however does not necessarily involve starting over, sometimes these offenders work to gain back and maintain their orig inal contacts like a job or a marriage in their quest to stop their criminal tendencies. Whichever path desistance takes these turning points often lead to: a knifing off of the past from the present opportunities for investment in new relationships that offer social support, growth, and new social networks forms of direct and indirect supervision and monitoring of behavior structured routines that center more on family life and less unstructured time with peers situations that provide an opportunity for identity transformation and that allow for the emergence of a new self or script These factors, they explain are true and are not affected by the type of marriage and the crime life of an individual , though informal, cohabiting and parenthood have also been linked to successful desistance (Sampson and Laub, 2006; Katz, 1999). Individuals with none of these social bonds are also more able to stop offending because, they have nothing to lose. Rebecca Katz (1999:13) indicates that, families of procreation may play a significant role in developing desistance since family influences self control and delinquency. Life course theory emphasizes on the strong influence of the social environment to offending explaining that absence of criminal peers reduces the chances of an individual ever engaging in offences and consequently attitudes and beliefs favorable to conformity will develop (Warr, 1998; cited in Sampson and Laub, 2003). Life Course Theory contradicts the link between developmental theories in criminal careers and desistance. It agrees that adulthood experience s are essential as well but to some point more significant in establishing the possible trajectory of desistance (2003). Offenders desist as a result of individual actions (choice) in conjunction with situational contexts and structural influences linked to key institutions that help sustain desistance. As such we argued that desistance is a process rather than an event, and that It must be continually renewed. This fundamental theme underscores the need to examine individual motivation and the social context in which individuals are embedded. (Sampson and Laub, 2003:171) Agency Yet another essential element that has been pointed out as key in achieving successful desistance is agency. (Burnett, 2004; Maruna, 2001; McNeill, 2006; Maguire et al, 2006; Maruna, 2001; Sampson and Laub, 2005 a). The theory of rational offence understands the fact that a criminal is able to make decisions based on his judgment of what is good or bad according to him in his crime life. Agency therefore works hand in hand with rational choice in the key decision making processes of a criminal. Agency is important since it assists in the overall process of making a rational choice. Furthermore, considering the often irrational patterns of offending of many criminals, and the many economic and social constraints offenders live under, rational choice theory alone cannot account for decisions to desist (Burnett, 2004; Sampson and Laub, 2005b). In their study of the Gluecks men Sampson and Laub (2005a) found that agency was a vital component in successful desistance. There is more to the structural support in the process of desistance, agency is required to offer the determination and persistence part of the equation. Agency determines the will to keep moving on and only those who are persistent will be able to manage the whole process. This will to desist and the internationalization of responsibility to overcome the challenges offenders face as they undergo desistance (Maruna, 2001), is very difficult to measure or predict and introduces a seemingly random component into life course turning points, making neat prediction inherently a difficult endeavor (Sampson and Laub, 2005a:177). Moreover it is a quintessential component in the study of desistance and persistence in a criminal career that has however not been fully researched to date. In their research of the life course theory of life Sampson and Laub assert that they have been seeking to explain the importance of the human agency as an aid in understanding desistance and other deviance forms (2003:177). Knifing offà ¢Ã¢â€š ¬Ã… ¸ ones past, has come out to be a vital element to describe the ability to be able to accomplish a successful desistance for some individuals. To achieve this voluntarily, agency is necessary since it is one of the most difficult things to do and needs a lot of determination. It is a process that is more often accompanied by cutting all past contacts and establishing new ones for example geographical location and family. Most importantly though, Maruna et al (2006a) explained that it can as well involve internal change, or a change in the way the offender views themselves, their past, and their environment. This change in the individuals thinking is vital for the maintenance of long term desistance (Maruna, 2001; Sampson and Laub, 2003; 2005a; Maguire et al, 2006). Contemplation time was found to be a crucial moment that assisted in creating a turning point to desistance according to a study by Margaret Hughes (1998). And it was found that the opportunity to contemplate came as a result of a change in geographical location, imprisonment and residential treatment programmes. Hughes participants found their desire to change develop when they removed from the usual environments and being able to get ample time for self actualization. Social identity Researchers have tried to explain the phenomenon whereby some individual are able to sustain long term resistance while others do not, and it has been discovered that apart from agency, an individuals self identity change is similarly necessary. The chance of an ex-offender remaining crime free very much depends upon developing a new identity, and new values and beliefs that were not compatible with criminal offending (Burnett, 2004). For sure, a significant amount of work done in rehabilitating offenders and addicts, such as 12 Step and cognitive behavioral therapy, targets change in the individuals self-perception (Maruna, 2001). Each and every individual, whether an ex-offender, offender or normal citizen has a unique self identity through which their actions are guided upon, it is therefore as a result of this mechanisms that give people the different circumstances they exist in. Crucially, self-narratives provide a subjective account of the meanings that offenders place upon changes and turning points in their lives (McNiell, 2006).More often though not a fact; self narratives have been of assistance when people seek to explain their actions. Narratives very often change throughout the life course and understanding narratives, helps individuals realize the significance of past and present events in our lives (Sampson and Laub, 2005a). In a desistance study in Liverpool, Shadd Maruna investigated the different self narratives of two distinct groups of offenders whereby one persisted and the other desisted, to account for the changes in ex-offender identities (Maruna, 2001). He was able to find out that both the desisting and persistent criminals actually had more or less the same personality characteristics and were not as agreeable and conscious as the general population. Self-narratives are the only components that divided the two groups after thorough interviews. Active offenders had what Maruna described as a, condemnation scriptà ¢Ã¢â€š ¬Ã… ¸ (2001), meaning, they saw life as an unfortunate abyss of hostility and uncertainty. They believed that circumstances had pushed them to their present situation and there was nothing they could do to change things and that the authority pushed them even further away. Desisting ex-offenders on the other hand had a positive outlook on their past and present and this is wha t assisted them to continue with their desistance process. It is this self-narrative that may be the tool needed for successful desistance. The self-narrative of the ex-offenders holds a version of the truth that is often quite different from historical truth (Maruna et al, 2007). This self narrative attaches a psychological component to the real facts of the past and creates a purpose and meaning in the life of an offender. This is what brings about the positive outlook and assists in achieving desistance. In a study focused completely on religious changes of rehabilitated offenders, Maruna et al discovered that their self-narrative was interestingly changed by their conversion experience (Maruna et al, 2006b). As a result the importance of this self narrative is once more highlighted as it helps an offender realize that the past can be changed and that the future has a hope even for those in long sentences. The offender is therefore able to have a new sense of identity, empowerment, purpose and forgiveness. The self narratives of most offenders in the desisting group have a common characteristic Maruna describes as, the redemption scriptà ¢Ã¢â€š ¬Ã… ¸ (2001). This is basically the belief that an offender is a good person and that his or her past was merely as a result of circumstances of crime, recidivism and addiction. As a result of this, the offenders are able to endeavor to live new lives as they continue in with their desistance. They are then able to view themselves as role models with the necessary knowledge and experience to advice and educate the next generations, something Maruna calls, Making Goodà ¢Ã¢â€š ¬Ã… ¸. The major difference therefore between the desisting offenders and the persistent ones is the positive energy they surround themselves with. Confidence and self belief are as a result pointed out to be essential qualities as they guide an offender to understand that their past was a necessary component for them to be where they are at the present. This redemptive narrative helps them realize that they are not their past and that their future is what that matters. The acknowledgement of a supreme power beyond them has also been a contributing factor in the lives of these offenders. This is because they realize that their past might have been a plan to give them the positions they hold in the present, like being counselors and youth leaders. This moral superiority and change from the past, according to Maruna, is to make up for long stretches of lost life. During desistance according to Stephen Farrall some offenders undergo long periods of creating new social identities (2006:85). However much these offenders change, it is not forgotten that they acknowledge they are responsible for their criminal past. The idea that reformed criminals accept blame and feel shame for all of their crimes is not supported by research (Maruna, 2007). Successful offenders in desistance often admit to the guilt of their past but they however rationalize their actions and justify or blame themselves and accept that circumstances might have pushed them to criminality. Sometimes however they do not accept their actions and believe that the society pushed them to crime. Such a belief system would not encourage an ex-offender to accept responsibility for breaking laws that they perceived to be based on middle class values, and representative of a society that had neglected and mistreated them (Maruna, 2001). The Liverpool Desistance Study prove that a concurrent characteristic of the redemption script is an offender accepting to take control of changing his future however they do not acknowledge their past crimes. An internalization of full responsibility for their future, including the determination to overcome the many obstacles they will face, seems to be a defining feature of successful desisting ex-offenders. Maruna (2001:88) summarizes the themes of the desisting persons narrative as: an establishment of the core beliefs that characterize the persons true self an optimistic perception (some might say useful illusion) of personal control over ones destiny the desire to be productive and give something back to society, particularly the next generation Moffitt Adolescence-Limited and Life-Course-Persistent Antisocial Behavior: A Developmental Taxonomy Moffitts (1993) concept of dual taxonomy of offending similarly tries to explain the processes of desistance and persistence. Moffitt (ibid) outlined that offenders can be grouped into two; adolescent limiteds and life persisters. Moffitt proposes that the two groups are different and unique from each other in their offence and desistance processes, with the life course persisters having a different aetiology to the adolescent limited offenders. It is explained that they may be suffering neurological problems that affects their cognitive and learning skills. This is therefore evidenced by poor social skills even in the family leading to the various forms of anti social behavior and poor self control Gottfredson and Hirschi (1990). Early signs of antisocial behavior are a common characteristic of life course persisters (for example under-age drinking, premarital sex) as a result they are often excommunicated from their initial societal setting because of poor behavior, development and social bonds. Early signs of antisocial behaviors like these are normally a clear indication of a persistent criminal career in the future. This will be in connection to the age graded theory meaning there patterns of crime will be different and theirs will be a continuous cycle of events of affected marriages, work, education and relationships. Moffitt continues to explain that unlike life course persisters, adolescent limited offenders are not affected by any neurological problems and are able to successfully develop their social networks and cognitive skills. Therefore the causal factors for their criminality are connected to the gap between social development, age and desires. Age for example prevents them from engaging in adult behavior like sex or drinking. As a result of deviance from their desires, they tend to associate with the life course persister leading to the growth of their deviance. However, due to their developed social skills and academic success they are likely to be able to change more easily if they choose desistance. This is because they will be able to depend on their strong social bonds for support. Maruna (cited Laub Sampson 2001) explains that finding continuity in the criminality maybe be caused by methodology, by concentrating on dispositional traits to the exclusion of other personality traits. People can be able to change as Laub and Sampson write, even if their characteristic personality traits do not change radically with time. In order to understand desistance , researchers need to explore other aspects of personality such as offender self-perceptions or personal strategies Maruna (cited ibid). Narrative script There are two distinct narrative script types in the desistance literature that highlight how criminals really view themselves and their societal roles. For the persisters their script usually has a concurrent theme of condemnation. More often they blame external conditions like poor family relations and lack of education for their criminality. They generally have an external locus of control. In contrast the offenders who finally become successful in desistance have a redemption script. They are complete opposites of the latter and are fully responsible for their actions. As a result they make a positive choice to stop the crime by accepting rehabilitation programmes. They are described to have an internal locus of control. Factors that influence the particular narrative script that gets adopted by a criminal are majorly internal factors such as personality and genetics especially after rehabilitation. A higher chance of a redemptive script is noted to be as a result of intense rehabilitation. A probation workers relationship with an offender has also been linked to affect desistance. It is there important for these officers to have empathy skills that are crucial in the process of guiding an offender to desistance as they strive to be able to re-integrate back into the society. Relevance of desistance theory The desistance theory is relevant in a number of different applied and academic professions. The desistance theory to researchers may provide a foundation to be able to examine the different factors that contribute to the cessation of a criminal offence from a theoretical view. The desistance theory allows for a number of different crimes in history and their approaches like the Lombrosian biological positivism, to have consideration in the present society which has an evident difference in its ways of thinking. As a result criminology is more understood and its relationship with other disciplines like psychology, politics and social policy acknowledged. This will consequently allow the development of collaboration for a positive cause of reducing re offence rates. The desistance theory on a practical level has assisted the criminal justice system (CJS) to identify possible solutions to cases of reoffending of successful candidates of desistance through for example initiating community based sentences. This kind of programme is sure to gradually decrease the number of criminals in HM Prison Service institutions for short periods. Studies have shown that short-term sentences in prisons for example (those for less than six months) often lead to increased crime rates after release. This is well explained by the fact that these short-term prisoners to not undergo complete metamorphosis from not covering all the rehabilitation programs. Their exposure to the hard core criminals in the prisons who have been there for longer and have been experienced criminals also contributes to their overall change. In addition desistance theory assists in the continuous development of training programmes for the respective professionals responsible for working with ex-offenders in the community. For example the Probation Service (see Narrative script section, above). Controversies It is important for the general public to realize that desistance is achievable and takes time. Offenders should therefore not be viewed as bad people who cannot live with others even after rehabilitation programs. The public is therefore advised not to discriminate these groups of people in their society. Reintegration cases of offenders back into the society have always caused massive outrages by a large percentage of the public community. There are numerous related cases of such circumstances that have often been quite difficult and delicate to handle. For example in 2011, the case of the reintegration of Jason Owen who was initially convicted of playing some part, albeit minimal, in the widely reported death of Baby P (now known to be Peter Connelly) in 2007, and after serving his sentence for causing or allowing the death of Peter he was later released in 2011. The Sun newspaper immediately kicked off a campaign to find him. Readers were urged to write and report to the newspaper of any knowledge of his whereabouts. There was an article in the same newspaper that sent sentiments of outrage over the fact that the ex-convict had actually tried to find a job. This is a clear indication of how the effort of successful psychological research can be nullified by news reports in the popular media. This kind of outrageous reporting is especially a common characteristic of Tabloid newspapers. Their influence over the public is often impressive and they are as a result able to manipulate and affect the attitudes of the wider public towards their view of desistance and offenders. As a result of this, future recidivism is often developed gradually due to the ill-informed public. Newspapers then use this recidivism as proof of their initial correctness. Conclusion

Ethics of Dissection The use of dissection in classrooms is able to expand the knowledge of students by giving them a hands-on approach to anatomy. Dissection is one topic that is highly debated among all people who question whether it’s an ethical thing to do. According to Webster’s Dictionary the definition of the word ‘ethical’ means morally right and good or pertaining to right and wrong. The line between right and wrong is often a very thin line and many people don’t know where one ends and the other begins. I believe that dissection is an ethical way to get students more involved in learning and can give students a better understanding of the anatomical and physiological make-up of a once living organism. Creating an environment where kids are able to move around to learn instead of sitting in desks all day is important in the teaching process because the kids are able to participate directly, especially in dissection, without a teacher doing it for them. The National Science Teachers Association supports the idea of bringing in animals for dissection. â€Å"Student interaction w...

Tin and Nitric Acid

Jarrett Sears Dr. Hummel Chem 121 2/7/13 A Chemical Reaction between Tin and Nitric Acid Introduction: Finding the products made from the components of tin metal and nitric acid is the ultimate objective of this lab; the formula of the products will be found in the CRC handbook thereafter. Procedure: First, obtain a clean crucible, and heat it under a Bunsen burner until it is as hot as possible, about 15 minutes within a fume hood unit. The Bunsen burner will be used under the fume hood for the entire duration of the lab. Place a crucible on a wire gauge, and wait for the crucible and its lid to cool off completely.After cooling, obtain the weight of the crucible and lid by placing it on a petri dish to be placed on an electric balance (petri dish mass must be obtained prior) without using any hands; there will not be any touching of the fingers or hands to or on the crucible and subtract the mass of the petri dish to obtain the mass of crucible. (Mass is noted at 61. 805g with cruc ible and petri dish, crucibles mass: 25. 253g) tin is weighed between 0. 9000g and 1. 0g (for this expirement, . 98g is weighed) and added to the crucible, which is placed back onto the non. ignited Bunsen burner.While the crucible is being held by the Bunsen burner stand, 10M Nitric acid is dropped into the crucible with the tin unitil there is no longer any kind of reaction from it. This takes nearly 100 drops. It will bubble and fumes will arise. When nothing further occurs after ten minutes, the Bunsen burner is lit with the tin and nitric acid inside. Heat for about 15 minutes, let the crucible with the now contained tin oxide, cool on the wire gauze again and measure its mass. Repeat the heating process without adding anything to the crucible for an additional 15 minutes.After finding the mass of the tin oxide, by subtracting the initial weight of the crucible from the weight of the crucible with the tin oxide, we can compare the two measurements. Data: Grams Petri dish36. 552 With Crucible61. 805 Crucible alone with lid25. 253 Tin0. 98 After first run63. 043 Tin oxide:1. 238 Drops of nitric acid:100 Measured Oxygen:0. 258 2nd run of oxygen0. 253 Mass percentage of Tin: Oxygen79. 2%:20. 8% Moles of tin0. 0083 Moles of oxygen0. 01612 Discussion: After the nitric acid is applied to the tin filled crucible, the reaction has already began, after only a few drops, fumes start venting out of the crucible.There is . 98g of tin in the crucible; the nitric acid applied (100 drops: it is not necessary to weigh this for the ultimate objective of finding tin to oxygen ratio) may weigh 3 grams (hypothetically). There would be a net mass of 3. 98 grams, but due to the fumes of the reaction, some of this net mass is lost already before the burner is even turned on. This proves true even further once the burner is lit; brown fumes will be emitted from the crucible that we find later to be nitrogen dioxide in the CRC handbook. After heating and cooling, the crucible is n ow 1. 238g heavier than the empy crucible.After equating the mass of the now tin oxide, 1. 238g, we now find the tin to oxygen ratio. There is . 98 g of tin and . 258g of oxygen in this product, dividing this by their respective quantity of AMU found via the periodic table will give us the number of moles, 0. 0083 moles of tin in 0. 98 grams, or 8. 3 X10(3rd). There are 0. 01612 moles of oxygen in 0. 258 g of oxygen or 1. 612X10(3rd) this is the mass combined to the tin. When we divide these moles by the smaller figure, we then learn the empirical formula; this is our 1:2 ratios are found. Oxygen consists of 20. percent of the final mass, while tin is the remaining 79. 2%. Nitrogen is found by process of elimination, four different oxides of nitrogen are looked up in the CRC handbook: HNO3, NO, N2O, and NO2. NO2 is the only gas that is brown amongst this group. Sources of error would entail heating the crucible for duration of time too short for the reaction to finish, resulting in a heavier compound, and jeopardizing the legitimacy of the entire experiment. It could potentially leave the demonstration with nothing to be learned if there is not a 1:2 ratio after finding the inaccurate molar masses.Conclusion: This is to understand how reactions occur, and sometimes need more than to just be mixed together, heat is needed. Also, the ratio of mass does not infer ratio of atoms, far from it. The 1:2 tin oxide ratio results when one molecule of tin (Sn) combines with 2 nitric acid molecules (2HNO3), and the hydrogen is released as NO2 (byproduct) this is the fume referred to prior, where the value of mass is lost and the remains are the product of tin oxide: SnNO2.
