In this experiment, the following reaction enthalpies were determine: 1) NaOH(s) - NaOH(aq) AH = -41 kJ 2) NaOH(s) + HCl(aq)

Question

In this experiment, the following reaction enthalpies were determine:
1) NaOH(s) - NaOH(aq) AH = -41 kJ
2) NaOH(s) + HCl(aq) -NaCl(aq) + H₂O(1) AH = -108.9 kJ
Use Hess's law to determine the reaction enthalpy of
3) NaOH(aq) + HCl(aq) -NaCl(aq) + H₂O(1) AH = ? kJ
(Answer to 1 decimalplace)
