If 100. mL of 0.400 M NaOH and 100, mL of 0.400 M HCI both initially at 24.5°C react in a calorimeter, the final temperature of the surrounding solution is 27.2°C. What is the enthalpy change of this chemical reaction (in Joules)? Assume the density of the solutions are the same as water. (be careful with your signs)
