How much CO2 should you obtain?
That's 7.5 mol O2 x (2 mols CO2/1 mol O2) = 7.5 x 2 = 15 mols CO2 = theoretical yield
Then %yield = (Actual/theoretical)*100
80 = (Actual/15)*100
Actual = ?
a.Given the equation: 2CaCO3 + 2SO2 + O2 -> 2CaSO4 + 2CO2 What is the actual yield of CO2 if 7.5 mol of O2 gives a percent yield of 80%?
b. The pollutant sulfur dioxide can be removed from the emissions of an industrial plant by the reaction with calcium carbonate and oxygen. 2CaCO3 + 2SO2 + O2 -> 2CaSO4 + 2CO2 If this reaction proceeds with a 96.8% yield, how many kilograms of calcium sulfate are formed when 5.24 kg of sulfur dioxide reacts with an excess of calcium carbonate and oxygen gas?
