The purpose of this experiment was to observe how the change in solvent polarity affects the rate and to determine the kinetics of a solvolysis reaction. In this experiment‚ we used 1-chloro-1-phenylethane in acetone in one reaction with 50% ethanol-50% water and in another reaction with 40% ethanol-60% water. To monitor he rate of reaction‚ we would need the concentration of the alkyl chloride at the beginning of the reaction and at a time t‚ but since we did not determine the concentrations

Diabetes is an example of a non communicable disease. I chose diabetes because it is a very common disease that a lot of people live with so I would like to learn more about it. I want to learn about the disease itself and the symptoms that are associated with the disease. Then I want to learn about treatments to help with diabetes. And since I don’t have diabetes I want to learn what health practices I need to work on to prevent getting diabetes. These are all things this assignment will help me

yield and the mCPBA epoxidation reaction was 70% yield. Oxone is the greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic byproducts and recycles acetone in the epoxidation reaction. Introduction The epoxidation of an alkene creates an epoxide that is reactive to nucleophiles. This is important in organic chemistry as well as biological sciences. For example epoxide hydrolase aids in purification

! Isolation of the Components of BC Powder Introduction Aspirin‚ Caffeine and Salicylamide were extracted from an over-the-counter pain reliever (BC Powder). These components were separated by manipulating their solubilities by adjusting the acidity and basicity of the solution. By doing this‚ the three components were forced into conjugate acid (or base) forms‚ causing selective solubility in either an aqueous or organic solvent. These layers were then separated by use of a separation funnel

Experiment 1: Viscosity of Liquids Victoria Kulczak Lab Partners: Laina Maines & Heidi Osterman Date of Lab: 2/21/11 Due Date: 2/28/11 Abstract: The goal of this experiment was to determine the viscosity of given liquids. Two different methods were employed‚ the first measures time of flow of several methanol-water solutions‚ from point A to point B. The second method involves dropping a foreign object‚ in this case a sphere‚ into a cylinder of glycerol and measuring the time it takes for it to
