Evaluation dh for the reaction in kj

Reference no: EM13561021

A 50.0 mL sample of 1.00 M aqueous CuSO4 was added to 50.0 mL of 2.00 M aqueous KOH in a non-ideal coffee cup calorimeter. An initial temperature of 25.0 C and a final temperature of 31.0 C were recorded. The calorimeter's heat capacity was determined by mixing 100 ml of 80.0 C water into the cup containing 100 ml of 25.0 C of water. The final temperature was 52.0 C. Assume that the solution has a specific heat capacity of 4.184 J/(g K) and a density of 1.00 g/ml. Calculate dH for the following reaction in kJ.

CuSO4(aq) + 2KOH(aq) Cu(OH)2(s) + K2SO4(aq)
