If 50 ml of 0.20 M HCL(aq) are mixed with 50 ml of 0.20 M NaOH (aq), each at 22.2 C, what is the temp of the final solution after thermal equilibrium is established? The heat of neutralization -56kj/mol. Assume there is not heat lost to the surroundings. Also assume the specific heat of the solution is 1.0 Cal/g*c and the density of all solutions is 1.0g/mL
