Assignment Help Chemistry
Reference no: EM132252016

When 100.0 mL of a silver nitrate solution and 50.0 mL of a sodium chloride solution were mixed in a constant pressure calorimeter, the temperature of the mixture rose from 21.15 degrees C to 25.20 degrees C. If the density of the solution is 1.0 g/mL and its specific heat is 4.18 J/g degree C, how much heat is evolved by this reaction?
