Consider the following reaction: Solid calcium oxide reacts with carbon dioxide gas to form solid calcium carbonate. A chemist allows 14.4g of calcium oxide and 13.8g of carbon dioxide to react. When the reaction is finished, the chemist collects 19.4g of calcium carbonate. Determine the limiting reagent, theoretical yield, and percent yield.
