Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. What is a limiting reactant?
The reactant that produces the most product.
The reactant that is completely consumed in a chemical reaction.
The reactant that is left over after a reaction.
The reactant that has the largest molar mass.
2. In a chemical reaction, the determines the maximum amount of product that can be formed.
3. The reactant that is not completely used up in a reaction is called the reactant.
4. Consider the reaction: 2H₂ + O₂ → 2H₂O. If you have 10 moles of H₂ and 3 moles of O₂, which reactant is limiting? Show your calculations.
5. For the reaction: N₂(g) + 3H₂(g) → 2NH₃(g). If 28.0 g of N₂ reacts with 12.0 g of H₂, calculate the theoretical yield of NH₃ in grams. Identify the limiting reactant and the excess reactant.
6. The limiting reactant is always the reactant with the smallest initial mass.
