Synthesis of Benzoin Date of Experiment: 1-26-15 Chelsea Price Lab Partner: Joey Simmons Abstract: In this experiment‚ benzoin was synthesized from benzaldehyde‚ using thiamine hydrochloric acid as a catalyst. The thiamine HCl was deprotonated by sodium hydroxide and acted as a nucleophile to attack the benzaldehyde. A water-cooled condenser was used to heat the solution at reflux. Vacuum filtration was used to wash and dry the product. The benzoin product was recrystallized

Lab #1 ‐ Introduction to the Microscopy & Observation of Prokaryotic and Eukaryotic Cells Introduction Many of the cells and organisms that you will be studying are at the lower limits of visibility of light microscopes; therefore‚ it is extremely important that you attain critical lighting and focussing. It is also important to handle the microscope competently to avoid damaging either the microscope or the preparation you are studying

Title: the mechanism of carbon dioxide and oxygen exchange in the respiratory of human Abstract The purpose of the experiment is to determine gas exchange activity in the respiratory system of human. The first lab for comparing the room and breathe temperature was to understand the function of the nasal cavity where the gas passed after an inhalation. The second lab for changing of chest circumference and abdomen circumference between inspiration and expiration was to know how the air moved in

non- legal mechanisms in dealing with children and young people” There are many legal and non- legal mechanisms‚ which seek to gain justice for children and young people. The effectiveness of these mechanisms changes with different situations. There have been many law reforms‚ which have proved to be effective; although there are many areas‚ which need improvement. An issue that will be further discussed in this essay is young drivers and the law. The legal and non-legal mechanisms that I will

They are a household name famous for its signature “golden arches” and “supersized” fries. McDonald’s is an international corporation that manages several hundred independently owned stores. To effectively manage this type of corporation‚ McDonald’s must use several control mechanisms. Below is an analysis of

type of formula for an alcohol is R-OH‚ where the functional group is the hydroxyl group (-OH). The symbol R’ indicates that the two R-groups in the ester formula need not be the same. It has been shown by radioactive tracer methods that in the mechanism of the esterification reaction‚ the –OH group is split from the acid and the –H from the alcohol. Aspirin can be made as follows: C – OH C – OH CH3 – C – OH + HO –

superego is the mediating factor between the two. Defense mechanisms are coping mechanisms that protect us from conflict‚ anxiety‚ shame‚ guilt‚ and unacceptable feelings or thoughts. Defense mechanisms include avoidance‚ denial‚ rationalization‚ repression‚ regression‚ reaction formation‚ projection‚ displacement‚ compensation‚ undoing‚ humor‚ passive aggression‚ and sublimation. Denial and avoidance are two of the most common defense mechanisms I see in life whether it be through personal
