a constant-pressure calorimetry experiment, Hayoung mixed 100.0 mL of 1.00 M H2C2O4 solution and 100.0 mL of 1.00 M KOH solution. The initial temperature of both solutions is 20.00°C. After a while, she observed that the temperature of the calorimeter had reached a constant value at 26.61°C. Calculate the enthalpy of neutralization for the following reaction: H2C2O4(aq) + 2KOH(aq) → K2C2O4(aq) + 2H2O   Assume that solution has the same specific heat capacity and density as water, and the calorimeter absorbed a negligible amount of heat.
