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

Conclusion 1: In this first lab we attempted to discover which of the materials given to us were hydrates by heating them and then dissolving them in water. Our results showed that all of our substances were hydrates besides the sucrose‚ sucrose if the only one which did not both bring condensation when heated and dissolve in water‚ which agreed with our hypothesis because we also thought that sucrose was going to be the only one that wasn’t a hydrate. The only error that we may have encountered

1. Why did regulators take a closer look at Demand Media’s accounting? Demand Media capitalizes the fees paid to freelance writers over five years instead of expensing the costs as incurred. Typically‚ web media companies expense content creation costs as incurred. Demand’s unorthodox approach to accounting for writer expenses as acquiring and amortizing intangible assets spreads Demand Media’s expenses over time and reduces its current losses on its income statement. Thus‚ Demand Media’s accounting

CONCLUSION The BRICS Development Bank is expected to start operations in 2016‚ providing a crucial two-year window to state the policies and instruments that would define the scope of its operations. We think the BRICS countries should meet the call to develop an institution that is revolutionary in its vision and the manner in which it functions. The Bank is expected to not only address developmental challenges within the five countries that are leading it‚ but also generate greater resources for

Sleep deprivation is one of the most widespread health complications in the world. There is a lack of adequate cautioning concerning its increase and prevalence in modern day society. An individual suffering from the lack of sleep has to contend with both short-term and long-term repercussions and is also at a higher risk of suffering from several types of disorders. The purpose of this essay‚ consequently‚ is to examine the causes and effects of sleep deprivation and offer recommendations on how

Lab Conclusion When comparing the average speed results from part two of the lab and the definition of acceleration‚ you find similarities between the two. First‚ average speed is distance divided by time‚ and we use it to describe the motion of an object moving at changing speeds. We can see this from our lab results from the average speed of the marble traveling down the ramp‚ because it picks up speed. When the marble is released at the top of the ramp‚ the ball doesn’t have the same momentum

Conclusion In this experiment‚ we measured the mass of 4 gasses; oxygen‚ carbon dioxide‚ helium‚ and lab gas. We took a Ziplock bag‚ and turned into a non-stretchy balloon‚ and filled with each gas and measured the apparent mass then calculated the actual mass‚ then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide‚ and the lightest
