In a coffee-cup calorimeter, 140.0 mL of 1.2 M NaOH and 140.0 ml of 1.2 M HCI are mixed. Both solutions were originally at 22.8°C. After the reaction, the final temperature is 30.8°C. Assuming that all the solutions have a density of 1.0 g/cm² and a specific heat capacity of 4.18 1/°C g. calculate the enthalpy change for the neutralization of HCI by NaOH. Assume that no heat is lost to the surroundings or to the calorimeter. AH- kJ/mol
