Question

1) calcium hydroxide, which reacts with carbon dioxide to formcalcium carbonate, was used by the anceint romans as mortar instore structure. the reaction for this process is Ca(OH)2 (s)+CO2 (g)=CaCO3 (s)+H2)(g)                    H = -69.1 KJ what is the enthalpy change if 3.8 mol of calcium carbonate isformed? 1) calcium hydroxide, which reacts with carbon dioxide to formcalcium carbonate, was used by the anceint romans as mortar instore structure. the reaction for this process is Ca(OH)2 (s)+CO2 (g)=CaCO3 (s)+H2)(g)                    H = -69.1 KJ what is the enthalpy change if 3.8 mol of calcium carbonate isformed?
