During a laboratory experiment, 84.8 grams of iron Ill oxide reacted with an excess of carbon monoxide producing 54.3g of iron. What is the percent yield of iron in this reaction?
Fe2O3 + 3 CO ---> 2 Fe + 3 CO2

Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide as shown below. caco3(s) cao(s) + co2(g) the kp for this reaction is 1.16 at 800°c. a 5.00 l vessel containing 10.0 g of caco3(s) was evacuated to remove the air, sealed, and then heated to 800°c. ignoring the volume occupied by the solid, what will be the mass of the solid in the vessel once equilibrium is reached?
