The decomposition reaction of calcium carbonate is represented by the following balanced equation:

After a 15.8-g sample of calcium carbonate was heated in an open container to cause decomposition, the mass of the remaining solid was determined to be 9.10 g. The student is unsure if the reaction is complete, so the solid could contain unreacted CaCO₃.

(a) Determine the theoretical yield of CaO and the theoretical yield of CO₂.

(b) Determine the percent yield of CaO and the percent yield of CO₂.

(c) Why are the percent yields for CaO and CO₂ different?
