1. A chemist wants to determine the enthalpy of neutralization for the following reaction: HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l) The chemist uses coffee-cup calorimeter to neutralize completely 61.1 ml of 0.5 mol/L HCI with 42.6 ml of NaOH. The initial temperature of both solutions is 17.8C. After neutralization, the highest recorded temperature is 21.6C. Calculate the enthalpy of neutralization, in units of kJ/mol of HCI. Assume that the specific heat capacity of both solution is the same as the specific heat capacity of water. (3 A, 2C)
