Determine the heat of neutralisation for the following neutralisation reactions: (1) 100 L of 0.2 (M) HCl solution is mixed with 200 mL of 0.15 (M) NaOH solution. (2) 200 mL of 0.4 (M) `H_(2)SO_(4)` solution is mixed with 300 mL of 0.2 (M) KOH solution.
Given: `H^(+)(aq)+OH^(-)(aq) toH_(2)O(l),DeltaH=-57.3kJ`.
