Portland cement is a mixture of the oxides of calcium, aluminum, and silicon. The raw material for its calcium oxide is calcium carbonate, which occurs as the chief component of a natural rock, limestone. When calcium carbonate is strongly heated it decomposes. One product, carbon dioxide, is driven off to leave the desired calcium oxide as the only other product.
Write the balanced chemical equation for the decomposition of calcium carbonate (include physical states of the compounds in your answer):
A chemistry student is to prepare 1.50 x 102 g of calcium oxide in order to test a particular "recipe" for Portland cement. How many grams of carbon dioxide are produced?
