Suppose that 50.0 mL of 0.400 M HCl and100.0 mL of 0.200 M CsOH are mixed in a calorimeter. Determine the enthalpy change for the neutrilization. The solutions start out at 22.50 degrees C, and the densities of the solutions are all 1.00 g/mL and the final temperature after the reaction is 24.28 degrees C, and the specific heat of the mixture is 4.2 J/ (g x C). ralization reaction of 1.00 mol of CsOH in kJ?
