Determine the enthalpy change for the reaction below in kJ/mol-rxn, CaO(s) + CO2(g) → CaCO3(s) given the thermochemical equations below. Ca(OH)2(s) → CaO(s) + H2O(l) ΔH° = 65.2 kJ/mol-rxn Ca(OH)2(s) + CO2(g) → CaCO3(s) + H2O(l) ΔH° = −113.8 kJ/mol-rxn (Report your answer to the nearest whole number, i.e. xxx, with no decimal places.  Make sure to include a negative sign, if necessary.) (No units are necessary in answer.)
