Limiting and Excess Reactants

Problem Set IconNow that you have learned how to perform calculations to find the limiting and excess reactants, use dimensional analysis to provide answers to the questions below. Make sure to completely answer each question and to show all of your work.

This activity is available below or in a printable version.

  1. What is the limiting reactant if 1.22 g of O2 reacts with 1.05 g of H2 to produce water?
  2. Identify the limiting reactant when 5.1 g of lithium react with 1.5 L of fluorine gas at STP to produce lithium fluoride.
  3. When 4.1 g of Cr is heated with 9.3 g of Cl2, what mass of CrCl3 will be produced?

Once you have completed the calculations using dimensional analysis, please submit your work to the dropbox.
