Calculating Quantities and Classification of Chemical Reactions Lab

Purpose: I. The objective of this laboratory experiment is to be able to identify and precisely classify each reaction as one of the five different types of chemical reactions by comparing the reactants from the product. II. The purpose of this laboratory experiment is to accurately calculate quantities of the products and the reactants, Aluminum and Copper (II) Chloride, in the chemical reaction to determine its percent yield.

Data Tables:
I.

Reaction #1

Observation of Gas Before Reaction Observations of Gas After Reaction
“Nothing”
(Invisible from the naked eye) Blue flame
(as the gas was lit)

Reaction #2

Mass of Magnesium & Bowl Before Observations of the Magnesium Before Mass of Magnesium & the Bowl After Magnesium Observations After
39.2 g Hard, grey strip 39.2 g -Ashes on the bowl
-Burnt dull strip remained
