Review Intelligent Tutoring Problem 6.65 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 97.13 kJ °C-1. The reaction raised the temperature of the calorimeter to 27.282 °C. Write the balanced chemical equation for the reaction in the calorimeter. How many joules were liberated in this reaction? What...
