Consider the equation for neutralization of calcium hydroxide (Ca (OH) 2) by hydrochloric acid (HCl).

Ca (OH) 2 (aq) + 2 HCl (aq) 2 H2O (l) + CaCl2 (aq) ∆H = -125 kJ / mol of HCl (aq)

In the laboratory, a volume of 150 ml of calcium hydroxide at a concentration of 0.500 mol / L is taken and mixed with 200 ml of hydrochloric acid at a concentration of 0.375 mol / L. These two solutions are at an initial temperature of 23.0 ° C. What is the final temperature of the mixture when the neutralization reaction is complete?

1)23.0 ° C

2)16.6 ° C

3)6.4 ° C

4)29.4 ° C
