Ethanoic acid is neutralized by sodium hydroxide. CH3COOH(aq)+NaOH(aq)→CH3COONa(aq)+H2O(l)\text{CH}_3\text{COOH}(\text{aq}) + \text{NaOH}(\text{aq}) \rightarrow \text{CH}_3\text{COONa}(\text{aq}) + \text{H}_2\text{O}(\text{l}) When 0.048 moles of ethanoic acid is mixed with 0.040 moles of sodium hydroxide, the heat energy change of the reaction, QQ , is 2.09 kJ. Calculate the enthalpy change, ΔH⊖\Delta H^\ominus , of the reaction.
