Which skeleton equation is correct for this question below:?
Calcium carbonate reacts with sulfur dioxide gas and oxygen gas to produce solid calcium sulfate and carbon dioxide gas. The correct skeleton equation for this reaction is:

A. CaCO(s)+SO(g)+O(g) -- CaSO(s)+CO(g)
B. CaCO2(s)+SO2(g)+O3(g)--CaSO2(s)+CO2(g)
C. CaCO3(s)+SO2(g)+O2(g) -- CaSO4(s)+ CO2(g)
D. Ca(CO3)2(s)+SO2(g)+O2(g)--Ca2SO4(s)+CO2(g)

Like Oh_hai said, the answer is C. If you make the assumption that one of them HAS to be correct, you can answer the question by looking only at the first reactant. Each one of them is different, and only one of them is truly calcium carbonate: the one present in answer C.
