When 50.0 mL of 0.400 mol L-1 Ca(NO3)2 is added to 50.0 mL of 0.800 mol L-1 NaF, CaF2 precipitates, as shown in the net ionic equation below. The initial temperature of both solutions is 24.0 °C. Assuming that the reaction goes to completion, and that the resulting solution has a mass of 100.00 g and a specific heat of 4.18 J g-1°C-1, calculate the final temperature of the solution.

      Ca2+(aq) + 2F-(aq) → CaF2(s)  

Δ

rH = -11.5 kJ

◦ 24.55 °C
◦ 25.10 °C
◦ 25.65 °C
◦ 23.45 °C
