Humans exhale carbon dioxide when they breathe. If the concentration of carbon dioxide in the air that people breathe gets too high, it can be fatal. Therefore, in space shuttles, submarines, and other sealed environments, it is common to use "air scrubbers" to remove carbon dioxide from the air. The air scrubbers on the space shuttle remove carbon dioxide by using lithium hydroxide (LiOH). The reaction in the air scrubbers is shown below: CO2 + 2LiOH Li2CO3 + H2O Each astronaut produces 8.8 × 102 g CO2 per day that must be removed from the air on the shuttle. If a typical shuttle mission is 9 days, and the shuttle can carry 3.50 × 104 g LiOH, what is the maximum number of people the shuttle can safely carry for one mission? CO2 + 2LiOH Li2CO3 + H2O 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. What is the limiting reactant in this test reaction?
