Shane T. Moore Sept.12‚ 2013 Experiment 1: SLIME (Starting Labs Is Mighty Exciting) Abstract In this experiment we investigate the properties of SLIME. Substitution of polyvinyl alcohol instead of Guar gum makes this experiment quite accessible. The Slime is prepared by mixing a solution of (Na2B4O7*10H2O) sodium tetraborate decahydrate (Borax) and H2O with a solution of polyvinyl alcohol (pva) and H2O. Then stirring

Title: The Recipe for the Highest Bouncing Super Ball Name: Date: November 14‚ 2013 Question: How much borax is needed from 1g to 5g to produce a super ball with the highest bounce from the height of 1.5m? Hypothesis: If 2 g of borax is used to make the super ball then it will produce the highest bounce because 2 g will make the appropriate number of bonds without producing a ball that is too soft or too hard to bounce. Materials: Paper cup Beaker Graduated cylinder Stir stick Pencil

Lab 8: Isopentyl Acetate CHM 2211L October 22‚ 2014 Abstract Many esters are naturally occurring compounds that are responsible for the fragrance of fruits and flowers. Isopentyl Acetate is the compound responsible for the smell of bananas. However‚ when Isopentyl acetate is treated with H3O+ it will hydrolyze back into the carboxylic acid‚ which will change the fragrance. In this experiment 3.11g of Isopentyl Acetate were produced with a 51.92 percent yield. Introduction Esters are carboxylic

Synthesis of Isopentyl Acetate Abstract Isopentyl acetate was synthesized via a Fischer Esterification and purified via simple distillation. The yield was determined to be 25%. The identity and purity of the product was confirmed by comparison of the measured ultra-micro boiling point (140°C) to the published value (142°C).1 Chemical Equation Procedure Isopentyl alcohol (0.787 g‚ 1.2 mL‚ 8.93 mmol)‚ acetic acid (1.574 g‚ 1.5 mL‚ 26.20 mmol)‚ and sulfuric acid (0.368

Synthesis of Isopentyl Acetate (Banana Oil) Using A Fischer Esterification Reaction Purpose: The purpose of this experiment is to synthesize Isopentyl Acetate using a Fischer esterification reaction. Fischer esterification is an acid-catalyzed condensation of an alcohol and a carboxylic acid‚ yielding an ester and water. Isopentyl Acetate has the scent of banana oil‚ once synthesized it will be purified by distillation. Then the analysis of the sample using H NMR and IR will determine purity
