The mass of the products and reactants is equal.
Reason: CaCO3(s) → CaO(s) + CO2(g). Mass is conserved, so 100.0 g of CaCO3 produces about 56.1 g CaO and 43.9–44.0 g CO2 (total ≈100 g). (If the CO2 gas escapes from the container, the remaining solid will weigh ~56 g, but the total mass of all products still equals the original mass.)
