When 13.6 g оf cаlcium chlоride, CаCl2, wаs dissоlved in 100.0 mL of water in a coffee cup calorimeter, the temperature rose from 25.00 °C to 31.75 °C. Determine the ∆Hrxn in kJ/mol for the reaction as written below. Assume that the density of the water is 1.000 g/mL, and that the specific heat capacity of the solutions is that of pure water. Must show your work (scratch paper) to receive credit. CaCl2(aq) → Ca2+(aq) + 2 Cl- (aq) ∆Hrxn = _________
