To investigate the physical properties of pure chemical substances. Procedure: For this lab we used four test tubes and poured equal amounts of a substance in each test tube. We then observed the color and odor. We then heated the substance and recorded the observation. The next tube we added cold water and observed the effects‚ then we heated it

Observations of Chemical Changes Purpose: The purpose of this experiment is to predict and examine chemical changes/reactions among common chemicals found in consumer products at a macroscopic level. Procedure: The procedure of this experiment was to carefully mix different chemicals together using the chemical filled pipettes and the 96-well plate and determining what chemical reactions occurred.

BIOL 140 Lab—The Chemical Composition of Cells Name ____________________________ I) Introduction All cells contain four major types of macromolecules: carbohydrates‚ lipids‚ nucleic acids‚ and proteins. In today’s lab‚ we will be studying three of the four-proteins‚ carbohydrates and lipids. Various chemical tests can be used to detect the presence of each of these molecules. Most of the tests involve a color change visible to the eye. If a color change is observed‚ the test is considered positive

Observations of Chemical Changes Page. 14 Objectives: The objectives of this experiment are: 1. To observe some properties of chemical reactions 2. to associate chemical properties with household products Background Information: Chemical changes are often accompanied by physical changes. Three that you should not see in this lab are changes in temperature‚ presence of a flame‚ and evolution of light‚ as when as firefly glows. Three physical changes that indicate a chemical change may have
