1. Calcium carbonate is decomposed by heating, as shown in the following equation. CaCO3(s)  ® CaO(s) + CO2(g) a. What is the theoretical yield of CaO if 24.8 g CaCO3 is heated? b. What is the percent yield if 13.1 g CaO is produced? Fe2O3(s) + 3CO(g)  ® 2Fe(s) + 3CO2(g) What is the percent yield of this reaction?
 * __THEORETICAL YIELD __**
 * 1) When 84.8 g iron(III) oxide reacts with an excess of carbon monoxide, 54.3 g of iron is produced.
