2. Calculate the mass of water produced from the reaction of 24.0 g of H2 and
160.0 g of O2. What is the limiting reagent?

3. The burning of 18.0 g of carbon produces 55.0 g of carbon dioxide. What is the
theoretical yield of CO2? Calculate the percent yield of CO2.

4. Calculate the percent yield of Cl2(g) in the electrolytic decomposition of
hydrogen chloride if 25.8 g of HCl produces 13.6 g of chlorine gas.

5. One method for reclaiming silver metal from silver chloride results in a 94.6%
