Two solutions primarily at 24.69 degrees Celsius are mixed in a coffee cup calorimeter (Ccal=105.5 J/ degrees Celsius). While a 200mL volume of .100 M AgNO3 solution is mixed with 100mL sample of .100 M NaCl solution the temperature in the calorimeter increases from 25.16 degrees Celsius. Determine Delta H in units of kj/mol AgCl. Presume that the density as well as heat capacity of the solutions is the same as that of water. State a balanced reaction for the process.
