Barry Allahyar Dr. Dodd CHEM 2122 2010-09-16 Experiment 19: Fischer Esterification‚ Conclusion The objective in this experiment was to efficiently perform an Fischer esterification of 1-butanol and acetic acid to form water and n-butyl acetate‚ and to confirm the esterification using IR spectroscopy analysis. It was found that 0.734 grams of n-butyl acetate was formed with a percent yield of 61%. The product was confirmed using IR spectroscopy and boiling point confirmation. The reaction mechanism

the effect of the mass of the fan cart on the acceleration of the cart. The mass of the fan cart was the independent variable and acceleration was the dependent variable. We kept the speed of the cart on medium‚ and calculated the acceleration and motion. As a result‚ we had figured out that the bigger the mass the slower the acceleration‚ as we all should have known. To calculate this we used the second law of Newton (F=ma). For the first experiment we got .233 (m/s/s) with a percent error of 76%

English 1A: Discussion Topics John Berger’s “Ways of Seeing” Topic 1: Berger argues that there are barriers to vision‚ problems in the ways we see or don’t see original works of art‚ problems that can be located in and overcome by strategies of approach. For this topic‚ discuss what‚ as you read Berger‚ gets in the way when we look at paintings‚ and what it is that we might do to overcome the barriers to vision (and to history). Imagine that you are speaking to someone interested in art‚ but someone

Objective In this experiment the purpose is to study the period of the pendulum with different masses. Secondly to also study the relationship in the different lengths of the string and how it affects the period. Thirdly to find the different (time) periods in the changes in the arc size. Theory If the pendulum is set ‚ the force of the motion is used to swing back and forth . where the t period is the time the pendulum takes to complete a cycle of oscillation. As t-1/f the complete distance of

In conclusion to the distillation lab‚ I think our data shows that our experiment went well. Our graph resembles the graph in the lab handout (graphs attached to lab notebook sheets). The fractional distillation shows the sharp slope between when the cyclohexane burns off and mostly only toluene remains. The microscale graph seems to be accurate because it shows the large jump where the cyclohexane is burned off. To view the apparatuses used in the experiment look at the attached pictures. To

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

drinking places in the United States were independent single-unit establishments with fewer than 20 employees.” Because 70 % of competitors were restaurants who could open and close at any time‚ new entrants did not need large corporate backing and were free to open anywhere. The ability of so many small competitors to enter and compete in the industry indicated a steep learning curve. The steep learning curve and low capital requirement was threat to the industry because of the ease of rivals to enter
