Objectives: 

1. Students will be able to calculate a Percent Yield for a chemical reaction via stoichiometry. 

2. Students will determine the percent yield of a product they produce via a laboratory investigation.

Warm-Up:

Part 1- Classify and balance the reaction below:

____  Al  +  ____  ZnNO₂  -->  ____  Al(NO₂)₃  +  ____  Zn

Part 2- Percent Yield Stoichiometry

What is the percent yield of a reaction in which 49.00 grams of Aluminum Nitrite (111.40 g/mol) was produced from the reaction of 230.0 grams of Zinc (I) Nitrite (165.01 g/mol) with excess Aluminum?
