Appropriately combine the measured enthalpies of reactions (2) and (3) to predict (delta)H1 for the following reaction: Reaction (1): CaCO3(s) + H2O(l) ------> Ca(OH)2 (g) + CO2 (g) (delta) H1 equals what? Based on the predicted enthalpy, indicate whether Reaction (1) is endothermic or exothermic. Reaction (1) CaCO3(s) + H2O(l) ----> Ca(OH)2(s) + CO2(g) Reaction (2) CaCO3(s) + 2HCl (aq) ----> CaCl2(aq) + H2O(l) + CO2(aq) Reaction (3) CaCl2(aq) + 2H2O(l) ----> Ca(OH)2(s) + 2HCl(aq)
