p[hysical chemistry
A 50.0 mL of 0.700 M copper (II) sulfate solution is added to a 50.00 mL of 1.00 M sodium hyroxide solution in a coffee cup calorimeter. The initial temperature of the two solutions is 22.5 oC and the highest temperature reached in the calorimeter after mixing is 25.7 oC. Assume that no heat is transferred to the calorimeter or the surroundings and that the heat capacity of the solutions is 4.18 J/g oC. Assume that density of each solution is 1.00 g/mL. Calculate the molar enthalpy change, in kJ/mol, for the precipitation reaction:
CuSO4 (aq) + 2 NaOH (aq) -----> Cu(OH)2 (s) + Na2SO4 (aq)
