In a constant-pressure calorimeter, 65.0 ml of 0.330 m ba(oh)2 was added to 65.0 ml of 0.660 m hcl. the reaction caused the temperature of the solution to rise from 23.60 °c to 28.10 °c. if the solution has the same density and specific heat as water (1.00 g/ml and 4.184 j/g·°c, respectively), what is δh for this reaction (per mole of h2o produced)? assume that the total volume is the sum of the individual volumes.
