WebOct 8, 2024 · answered • expert verified Determine the standard enthalpy of formation (in kJ/mol) of calcium carbonate (\DeltaΔHf°) from the thermochemical equations given below. WebOct 1, 2024 · Since only one O2 is in the reaction, multiply the reaction by 2 to get the second O2. This doubles the ΔHf value. Combining these equations gives. 2 S(s) + C(s) + \(3 O_2(g)\) → \(CO_2(g)\) + \(SO_2(g)\) This equation has the product side needed in the problem but contains extra two S and one C atom on the reactant side.
