A volume of 50.0 mL of 0.400 M HBr at 24.35 C is added to 50.0mL of .400 M NaOH, also at 24.35 C. The final temperature is 27.06 C. Assume the volumes are additive, the specific heat of the solution is 4.180 J g/C, and that the density of the solution is 1.00 g mL -1. Calculate the enthalpy change, delta H, in kj for the reaction: HBr (aq) +NaOH(aq) => NaBr (aq) +H2O (l)
