Problem- 50mL of an acid in a colorimeter at 21 degrees Celsius is added to 50 mL of base at 21 degrees Celsius. The calorimeter has a heat capacity of 15J/K and the final temperature is 31 degrees Celsius. Assume the density of all the solutions is 1.0 g/mL, the specific heat of the aqueous solutions and mixture is the same as water, and the volumes are additive. What is the heat of reaction in kJ?

I need proficient help to solve the above problem
