1. Find the values for enthalpy changes of formation of NaOH(aq), HCL(aq), KOH(aq), and KOH(aq) in an appropriate reference work. 2.Write the balanced chemical equations corresponding to the values found in question 1. 3. The enthalpy change for any reaction can be obtained by subtracting the sum of the enthalpy changes of formation of the reactants from the sum of the enthalpy changes of formation of the products. Use this method to obtain the value of the heat of formation for the reaction of NaOH(aq) and HCL(aq) and the value of enthalpy change of the solution for the KOH.
