In a coffee-cup calorimeter, 100 mL of 1.0 M NaOH and 100.0 mL of 1.0 M HCI are mixed. Both solutions were originally at (2.22x10^1) °C. After the reaction, the temperature is (2.9200x10^1) °C. Assuming all solutions have a density of 1.00 g/mL and a heat capacity of 4.18 J/°C.g, what is the enthalpy change for the neutralization of HCI by NaOH? Assume that no heat is lost to the surroundings or the calorimeter. Enter your answer in kJ. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Answer x10 units
