Determine the standard enthalpy of formation (in kj/mol) of calcium carbonate (\deltahf°) from the thermochemical equations given below. Ca(oh)2(s) \longrightarrow cao(s) + h2o(l) \deltah° = 65. 2 kj/mol-rxn ca(oh)2(s) + co2(g) \longrightarrow caco3(s) + h2o(l) \deltah° = -113. 8 kj/mol-rxn c(s) + o2(g) \longrightarrowco2(g) \deltah° = -393. 5 kj/mol-rxn 2 ca(s) + o2(g) \longrightarrow 2 cao(s) \deltah° = -1270. 2 kj/mol-rxn.
