15. A 100.0 mL of 0.200 M aqueous hydrochloric acid, is added to 100.0 mL of 0.200 M aqueous ammonia (NH3) in a constant pressure calorimeter of negligible heat capacity. The initial temperature of both
solutions is the same at 25.00 °C. The final temperature after mixing is 26.10 °C. Assuming the density of the solution = 1.00 g/mL and its specific heat = 4.18 J/g °C, calculate the AH per mole of reaction: NH4Cl (aq) HCl(aq) + NH3(aq) A) -58 kJ/mol B) -54 kJ/mol C) -50 KJ/mol D) -42 kJ/mol E) -46 kJ/mol
