Calculating the enthalpy change
50 cm³ of 2.0 mol dm-³ hydrochloric acid was added to 50 cm³ of 2.0 mol dm-³ ammonia solution. The temperature rose by 12.4℃. Calculate the enthalpy of neutralisation for this reaction. Assume that the density of the solution is 1.00 g cm-³, the specific heat capacity of the solution is 4.18 J g-¹ K-¹.
