Silveira Date of Submission: September 25‚ 2013 Lab Section: CHE110L*Z Purpose The purpose of this experiment is to use two common laboratory methods to see how mixtures can be separated based on physical properties. Paper chromatography will be used to separate the dye colors from M&M candy to see which colors contain yellow #5. Gravimetric separation will be used to separate salt and sand from a mixture. Procedure The procedure for this lab can be found on pages 16 – 30 in “General Chemistry

Taylor Hill Lab 6: Enzymes Purpose: The purpose of this lab is to test for enzyme activity‚ look at enzyme specificity‚ and how temperature affects enzyme activity. Hypothesis: I believe that the room temperature activity will produce the most activity. Materials: 3% hydrogen peroxide‚ a household blender‚ potatoes (3 medium size potatoes‚ that are peeled and quartered)‚ tap water‚ 8 test tubes‚ 8 transfer pipets‚ sugar packets‚ salt‚ a small saucepan‚ a refrigerator with a freezer‚ stove

Period 12 Chemical Aspects of Life & Spit Lab ABSTRACT: The objective for the Spit lab was to test two different types of crackers for the presence or absence of starch and of reducing sugars. Also‚ to test the chewed cracker‚ the one that didn’t have a reducing sugar‚ for the presence or absence of a reducing sugar with the saliva in it. Adding on‚ another part of the objective is to determine the effect of amylase on starch. For the Chemical Aspects lab‚ the objectives were to test for the presence

I.Purpose The purpose of this lab is to show how potential energy and kinetic energy is shown and transferred using a model rollercoaster. This lab also demonstrates the Law of Conservation of Energy. II.Introduction Potential and Kinetic energy have a very big relationship. The Law of Conservation of Energy states that “Energy cannot be destroyed or created‚ but can be transformed or transferred.” This lab will help demonstrate this law and show the conversion between Kinetic and Potential
