The romans used calcium oxide, cao, to produce a strong mortar to build stone structures. calcium oxide was mixed with water to give calcium hydroxide, which reacted slowly with carbon dioxide in the air to give calcium carbonate. ca(oh)2(s) + co2 → caco3(s) + h2o(g) calculate the standard enthalpy change for this reaction. kj/mol-rxn what is the change in enthalpy if 3.50 kg of calcium hydroxide reacts with a stoichiometric amount of carbon dioxide? kj
