Suppose 100.0 mL of 1.00 M HCl and 100.0 mL of 1.00 M NaOH, both initially at 25.0oC, are mixed in a Thermos flask. When the reaction is complete, the temperature is 31.8oC. Assume the solutions have the same heat capacity and density as pure water.
Compute the heat released (in kJ).
Use your value to evaluate the molar heat of the neutralization reaction:
H3O+ + OH- 2H2O(l)
