Two solutions, initially at 23.49 °C, are mixed in a perfect coffee cup calorimeter at the same temperature. When 100.0 mL of 0.395 M sodium chloride is mixed with 200.0 mL of 0.5 M X(NO3)2, the temperature increases to 27.86 °C. What is the AH°rxn for the reaction written below? (Assume the density (1.00 g/mL) and specific heat of the solutions are the same as water: 4.184 J/g°C.) Only enter your numerical answer. Do not enter units. X(NO3)2(aq) + 2NaCl(aq) →XCl2(s) + 2NaNO3(aq) AH°rxn = ? kJ
