Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. In a chemical reaction, the limiting reagent is the reactant that:
Is present in the largest amount.
Determines the amount of product formed.
Is leftover after the reaction is complete.
Is always a catalyst.
2. Which of the following is NOT a step in determining the limiting reagent?
Balance the chemical equation.
Convert mass of reactants to moles.
Calculate the theoretical yield of the product.
Determine the actual yield of the product.
3. The reactant that is completely consumed in a chemical reaction is called the .
4. The reactant that is leftover after a chemical reaction is complete is called the reagent.
5. Explain, in your own words, why it is important to identify the limiting reagent in a chemical reaction.
6. Consider the reaction: 2H₂ + O₂ → 2H₂O If you have 10.0 g of hydrogen (H₂) and 64.0 g of oxygen (O₂), identify the limiting reagent and calculate the theoretical yield of water (H₂O) in grams.
7. The theoretical yield of a product is determined by the excess reagent.
