Two solutions, 50.0 mL of 1.00 M BaCl2(aq) and 50.0 mL of 1.00 M Na2SO4(aq), both initially at 21.5 °C, are added to a calorimeter with a total heat capacity, after the solutions are added, of 1.10 kJ/ °C and the temperature rises to 22.7 °C. Determine qrxn per mole of BaSO4(s) formed in the reaction.
