Objective: Students will be able to stoichiometrically calculate the limiting reagents for chemical reactions.

Warm-Up:

Part 1- Classify and balance the reaction equation below:

__  Pb₃C₆H₅O₇ + __ Al₂(C₂O₄)₃ --> __ AlC₆H₅O₇ + __  Pb₂C₂O₄

Part 2- Limiting Reagent Stoichiometry

75.0 g of Lead (I) Citrate (810.71 g/mol) react with 20.0 g of Aluminum Oxalate metal (318.02 g/mol) 

1. What is the limiting reagent in this reaction?

2. How much excess reagent (in grams) would remain after this reaction?

3. What would the percent yield of Aluminum Citrate (216.09 g/mol) be in this reaction if 20.5 g was produced in the lab?

(reminder 1- Must calculate the theoretical yield to solve).

(reminder 2- Theoretical yield is the maximum amount of product that can form).
