To ensure that the air in the shuttle remains free of excess CO2, engineers test the air-purification system. They combine 1.000 * 103 g LiOH with 8.80 * 102 g CO2. The reaction produces 3.25 * 102 g H2O

The balanced equation that describes the reaction between lithium hydroxide and carbon dioxide to produce hydrogen and lithium carbonate is expressed 2LiOH + 2CO2 = 2LiCO3 + H2. We are given the mass of each reactant. The limiting reactant is lithium hydroxide, in this case.
