Question 6 of 8 > In a constant-pressure calorimeter, 70.0 mL of 0.330 M Ba(OH), was added to 70.0 mL of 0.660 M HCI. The reaction caused the temperature of the solution to rise from 21.82 °C to 26.32 "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, O produced)? Assume that the total volume is the sum of the individual...
