2010 Report Date: 20.12.2010 ABSTRACT In this experiment‚ the purpose was to investigate E1 elimination mechanism with the reaction of cyclohexanol to cyclohexene. The reaction was acid catalyzed dehydration of alcohol and with catalyst sulfuric acid cyclohexene was obtained from cyclohexanol. And the product was obtained from the simple distillation and later it was reacted with bromine and potassium permanganate. The observations and results were all recorded. Simple distillation

and conclusion astonish me seeing the efficiency of the principles of catalysis. Few of which I can cite here as. • First the most important are energy conservation‚ the principle on which catalyst work is lowering of activation energy‚ which ultimately reduces the reaction time. • Selectivity of the catalyst provides better use of raw materials and reagents. • The environmental issue is being solved to a much-desired extent‚ waste generation is minimum. The work up and separation of products become

The Social injustice and inequality in South Africa! English Final Essay Charmina Khanam 1128965 May 9th‚ 2013 603-102-MQ During the time of slavery in South Africa‚ the South African people were deprived of their homeland because the colonists colonized it. The white colonists snatched their land brutally and took their freedom of rights. In Nadine Gordimer’s‚ `` Country Lovers`` and Kate Chopin’s`` Desiree’s Baby``‚ both authors illustrate injustice and inequality within a society

Fixed variables: *External temperature *volume of HCl *Temperature –all 3 final runs were done on the same day so whether was not an issue and did not affect the results *Use of catalyst – a catalyst was not used in any of the experiments * Use the same person to observe the reaction because different people have different eyesight Background information relating to the experiment In this experiment we are looking at one effect that

The idea that "things do not change‚ we do" is incorrect. Although it can be the case at times‚ it is entirely inaccurate as the phrase "we do" in this view can be easily replaced by "circumstances". "Things" may not change‚ but circumstances‚ which we usually have no control over‚ certainly do change. Also‚ this view can be rearranged to state "things change‚ we don’t"‚ showing that people may be resistant to change. The main focus of the book Things Fall Apart is on the changes that not only take
