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

Alum Lab Conclusion The purpose of this laboratory was to use two different techniques to attempt to identify the melting point and the mole ratio of hydrated water to anhydrous aluminum‚ potassium‚ and sulfate of AlKSO4. The hypotheses were: if the alum was put in a capillary tube the melting point of alum will be able to be determined; and the water of hydration in alum crystals will be possible to determine if the alum is heated with a Bunsen burner.

In conclusion‚ after conducting the lab‚ the emergent properties of water were tested and proved. These trials and experiments were able to verify the adhesion‚ cohesion‚ polarity‚ temperature stabilization‚ solvency‚ and density changes exhibited by water. During the glass and wax paper lab‚ we observed the adhesive properties of water. When a droplet of water touched the glass‚ it dispersed immediately. The droplet placed on the wax paper remained intact and in droplet form. Also‚ when the

Questions & Answers About Your Hair System Density How do I know what density is right for me? The best way to determine what’s right for you is to match the density of your own growing hair on the sides and back. Example: If you have fine thin hair on your sides and back‚ it would be a mistake to order a density for the top more then your growing hair. If the density of the hair system is greater then the density of your growing hair the hair on the hair system will separate and not blend and mesh

INTRODUCTION It has been said that purpose of information systems is to get the right information to the right people at the right time in the right amount and in the right format. Because information systems are intended to supply useful information‚ we begin by defining information and two closely related terms‚ data and knowledge. One of the primary goals of information systems is to economically process data into information and knowledge. Data items refer to an elementary description of

FIELD EXPERIMENTS IN ECONOMICS By: Ravisha Sodha INTRODUCTION: Field experiments occupy an important middle ground between laboratory experiments and naturally occurring field data. The underlying idea behind most field experiments is to make use of randomization in an environment that captures important characteristics of the real world. Distinct from traditional empirical economics‚ field experiments provide an advantage by permitting the researcher to create exogenous variation in the variables
