*Focused on Calculation 2: The amount of acetic acid(vinegar) you
you need for the lab. Approximately 2 mL.
*Completed hypothesis (limiting/excess reactant) and lab.

37. Stoichiometry Lab Hypothesis:
Explain which reactant you think will be completely consumed, the limiting reactant.
Explain which reactant you think will be partially consumed, the excess reactant.

38. Stoichiometry Lab: Hypothesis
Explain which reactant you think will be completely consumed, the limiting reactant.
Explain which reactant you think will be partially consumed, the excess reactant.

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

41. Stoichiometry: Limiting Reactants
Limiting Reactant: completely consumed during a chemical reaction.
Excess Reactant: partially consumed during a chemical reaction

42. Stoichiometry Problems
N2H O > N H2O
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(N2H4)= excess reactant (some left over)
Oxygen (O2) = 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(O2), because it limits(controls) the amount of product that can be produced.
Accurately determine the amount of N2 and H2O in grams that should be produced if 2 grams of O2 reacts with 5.6 grams N2H4.
*Use the grams of O2 to accurately predict how much of each product can be produced.
