A 50.0 mL sample of a 1.00 M solution of MgSO4 is mixed with 50.0 mL of 2.00 M NaOH in a calorimeter. The temperature of both solutions was 23.2 ℃ before mixing and 29.3 ℃ after mixing. The heat capacity of the calorimeter is 15 J/°C. From this data, calculate the change in enthalpy (delta H) for the process. MgSO4 (aq) + 2 NaOH (aq) ⇾ Mg(OH)2 (s) + Na2SO4 (aq) Assume the specific heat and density of the solution after mixing are the same as those of pure water and that the volumes are additive.
