This question has multiple parts. Work all the parts to get the most points. The Romans used calcium oxide, CaO, to produce a strong mortar to build stone structures. Calcium oxide was mixed with water to give Ca(OH)2, which reacted slowly with CO in the air to give CaCO3. Ca(OH)2 (s) + CO2(g) CaCO3(s) + HO(g) a Calculate the standard enthalpy change for this reaction. AfH* (kJ/mol) -986.09 -1207.6 -393.509 -241.83 Species Ca(OH)2 (s) CaCO3(s) CO (g) HO(g) Standard enthalpy change = -69.831 b How much energy is evolved or absorbed as heat if 6.50 kg of Ca(OH)2 reacts with a stoichiometric amount of CO? Heat= Submit kJ/mol-rxn kJ Previous Next
