When heated, calcium carbonate decomposes to yield calcium oxide and carbon dioxide gas via the reaction
What is the mass of calcium carbonate needed to produce 53 L of carbon dioxide at STP?
You do this the same way as the butane/CO2 problem above.
The decomposition of 3.32 g CaCO3 results in an actual yield of 1.24 g of CaO. What is the percent yield of calcium oxide for this reaction?
CaCO3(s) → CaO(s) + CO2(g)
