When 500 ML of 0

question 13

Multiple Choice

When 50.0 mL of 0.400 M Ca(NO₃) ₂ is added to 50.0 mL of 0.800 M NaF,CaF₂ precipitates,as shown in the net ionic equation below.The initial temperature of both solutions is 30.00°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 ∙ °C) ,calculate the final temperature of the solution. Ca²⁺(aq) + 2 F^-(aq) → CaF₂(s) ΔH° = -11.5 kJ

• A)29.45°C
• B)30.55°C
• C)31.10°C
• D)31.65°C
