Based on C2H4 + 3 O2 = 2 CO2 + 2 H2O how many moles of O2 are required for the complete combustion of 45 g of C2H4?

if 14.0 g of C2H4 are reacted and the actual yield of H2O is 7.84 g, what is the percent yield of water in the reaction?

if 18.0 g of CO2 are produced, how many grams of H2O are produced?

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?
