Stoichiometry Lab: Conclusion: • Provide evidence from the experiment to explain which reactant was the limiting reactant and which was the excess reactant.

Stoichiometry: Limiting Reactants • Limiting Reactant: completely consumed during a chemical reaction. • Excess Reactant: partially consumed during a chemical reaction en. wikipedia. org

Stoichiometry Problems N 2 H 4 + O 2 -----> N 2 + 2 H 2 O 1. a. If some of the rocket fuel was left over after the reaction was complete, explain which reactant is the limiting reactant and which is the excess reactant. Rocket Fuel(N 2 H 4)= excess reactant (some left over) Oxygen (O 2) = limiting reactant, what is 100% consumed. b. Which reactant should you use to accurately predict the amount of products produced in this reaction? We will want to use the limiting reactant(O 2), because it limits(controls) the amount of product that can be produced. c. Accurately determine the amount of N 2 and H 2 O in grams that should be produced if 2 grams of O 2 reacts with 5. 6 grams N 2 H 4. *Use the grams of O 2 to accurately predict how much of each product can be produced.
