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:

____ Fe₃N₄ + ____ Ba --> ____ Ba₃N₂ + ____ Fe

Click here for the coefficients for the balanced chemical reaction.

Part 2- Limiting Reagent Stoichiometry

240.0 g of Iron (IV) Nitride (223.59 g/mol) react with 265.0 g of Barium metal (137.33 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 Barium Nitride (440.01 g/mol) be in this reaction if 270.0 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).
