A 1.000 mol sample of propane, a gas used for cooking in many rural areas, was placed in a bomb calorimeter with excess oxygen and ignited. The initial temperature of the calorimeter was 25.000°C and its total heat capacity was 96.94 kJ·°C-1. The reaction raised the temperature of the calorimeter to 28.294 °C. balanced chemical equation for reaction in calorimeter and how many joules were liberated in the reaction
