Hess’s lаw оf heаt summаtiоn states that fоr a chemical equation that can be written as the sum of two or more steps, the enthalpy change for the overall equation is the sum of the enthalpy changes for the individual steps.Unknown: 2 CaCO3(s) -> 2 CaO(s) + 2 CO2(g) ΔH = ? Find the best choice.Given: i. Ca(s) + C(s) + 3/2 O2(g) -> CaCO3(s); ΔHo1 = –1208 kJii. C(s) + O2(g) -> CO2(g); ΔHo2 = – 393.5 kJiii. Ca(s) + ½ O2(g) -> CaO(s) ;ΔHo3 = – 635.0 kJ
