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.

Observation of Chemical Change Course: General College Chemistry Purpose This experiment examines the reactions of common chemical s contained in consumer products. The purpose is to observe the macroscopic changes that these chemicals undergo. The goals of the experiment observe properties of chemical reactions and to associate chemical properties with household products. Procedure We do not have the ability to see with a naked eye individual atoms and molecules reacting during chemical changes
