At 21.5oC when 40.0 mL of 0.200 M HCl is added to the 40.0mL of 0.200 M NaOH also at 21.5oC in a coffee-cup calorimeter, the temperature of the resulting solution rises to22.8oC. Assume that the volumes are additive, and the specific heat of the solution and density are the same as pure water. Determine the delta H for the reaction, HCl + NaOH => NaCl +H2O
