In a constant-pressure calorimeter, 50.0 mL of 0.320 M Ba(OH), was added to 50.0 mL of 0.640 M HCI. The reaction caused the temperature of the solution to rise from 21.35 'C to 25.71 'C. If the solution has the same density and specific heat as water (1.00 g/mL and 4.184J/g • °C) respectively), what is AH for this reaction (per mole H,0 produced)? Assume that the total volume is the sum of the individual volumes. AH = kJ/mol H,0
