How to set up for problem 2

Name Chem 1 - Hess's Law Lab Extension was precipitated: 1. A 100. mL solution of 0.35 mol of Ca2+ (aq) was mixed with 0.50 mol of F- (aq) ions and CaF2 (s) Ca2+ (aq) +2 F (aq) → CaF2 (s) The temperature of the solution increased by 10.5°C. What was the enthalpy change for the chemical reaction? What was the enthalpy change for the production of 1 mol of CaF2? Assume that the solution has the same density and specific heat as water. 2.
