Question

Aqueous silver ions reacts with aqueous chloride ion to yield a white precipitate of solid silver chloride. When 10.0 mL of a 1.00 M AgNO3 solution is added to 10.0 mL of a 1.00 M NaCl solution at 25°C in a calorimeter, a white precipitate of AgCl forms and the temperature of the aqueous mixture increases to 32.6°C. Assuming that the specific heat of the mixture is 4.18 J g-1 °C-1, that the density of the mixture is 1.00 g mL-1 and the calorimeter itself absorbs a negligible amount of heat, calculate ΔH (in kilojoules) for the reaction.
