Read each question carefully and provide detailed answers. Show all your work for calculations.
1. In a chemical reaction, the limiting reactant is the one that:
Is present in the largest amount.
Determines the amount of product formed.
Is leftover after the reaction is complete.
Is the most expensive reactant.
2. What is theoretical yield?
The actual amount of product obtained from a reaction.
The maximum amount of product that can be formed from given amounts of reactants.
The percentage of product obtained compared to the theoretical yield.
The amount of reactant that is completely consumed.
3. The reactant that is completely consumed in a chemical reaction is called the reactant.
4. The amount of product actually obtained from a reaction is known as the yield.
5. Consider the reaction: 2H₂ + O₂ → 2H₂O. If you have 10 moles of H₂ and 7 moles of O₂, identify the limiting reactant and the excess reactant. Justify your answer.
6. For the reaction: N₂ + 3H₂ → 2NH₃, if 28.0 g of N₂ reacts with 12.0 g of H₂:
a) Determine the limiting reactant.
b) Calculate the theoretical yield of NH₃ in grams.
c) If 30.0 g of NH₃ is actually produced, calculate the percent yield.
7. The actual yield of a reaction can sometimes be greater than the theoretical yield.
