Macmillan Learning In a constant-pressure calorimeter, 55.0 mL of 0.300 M Ba(OH)₂ was added to 55.0 mL of 0.600 M HCl. The reaction caused the temperature of the solution to rise from 24.10 °C to 28.19 °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 H₂O produced)? Assume that the total volume is the sum of the individual volumes. AH = x10 TOOLS kJ/mol H₂O

A student runs two experiments with a constant-volume "bomb" calorimeter containing 1300. g of water (see sketch at right). thermometer stirrer First, a 8.000 g tablet of benzoic acid (C6H₂CO₂H) is put into the "bomb" and burned completely in an excess of oxygen. (Benzoic acid is known to have a heat of combustion of 26.454 kJ/g.) The temperature of the water is observed to rise from 10.00 °C to 47.00 °C over a time of 5.8 minutes. olo Next, 5.940 g of ethylene (C₂H4) are put into the "bomb" and similarly completely burned in an excess of oxygen. This time the temperature of the water rises from 10.00 °C to 55.55 °C.
