When 50.0 mL of 0.900 M Ca(NO3)2 is added to 50.0 mL of 1.80 M
NaF, CaF2 precipitates, as shown in the net ionic equation below.
The initial temperature of both solutions is 30.00°C. As the
reaction proceeds, the temperature rises to 31.50 °C. Assuming that
the reaction goes to completion, and that the resulting solution
has a mass of 100.0 g and a specific heat of 4.18 J/(g ∙ °C),
calculate the ΔH° for this reaction, expressed in kJ/mol...
