Show all wórk för 1) Consider this constant volume (bomb) calorimetry experiment that was performed in a laboratory: a. A constant volume (bomb) calorimeter was calibrated in an analytical laboratory by burning 1.057g of benzoic acid (CH&O2) which has an enthalpy of combustion of-3228 kJ/mol. The temperature of the calorimeter rose from 22.75°C to 29.00°C. What is the heat capacity...
