.You now have the enthalpies of reaction for the following reactions: CaCO3 (s) + 2HCl(aq)->CaCl2 (aq) + CO2 (g) + H2O(l) ∆Ho1 CaO(s) + 2HCl(aq)->CaCl2(aq) + H2O(l)∆Ho2 The enthalpy for the CaCO3 reaction is -18.5 kJ/mol CaCO3 The enthalpy for the CaO reaction is -85.35 kJ/mol CaO Manipulate these reactions so that when they are all added together, the result is the formation reaction for the decomposition of CaCO3: CaCO3(s) -> CaO(s) + CO2(g). From these manipulations, calculate the value of ∆Ho for the overall reaction.

Question
24.You now have the enthalpies of reaction for the following reactions:
CaCO3 (s) + 2HCl(aq)->CaCl2 (aq) + CO2 (g) + H2O(l) ∆Ho1
CaO(s) + 2HCl(aq)->CaCl2(aq) + H2O(l)∆Ho2
The enthalpy for the CaCO3 reaction is -18.5 kJ/mol CaCO3
The enthalpy for the CaO reaction is -85.35 kJ/mol CaO
Manipulate these reactions so that when they are all added together, the result is the formation reaction for the decomposition of CaCO3: CaCO3(s) -> CaO(s) + CO2(g). From these manipulations, calculate the value of ∆Ho for the overall reaction.
