Heat of Combustion for C6H4O2: q (kJ/g) & q (kJ/mol)

Click For Summary
SUMMARY

The heat of combustion for quinone (C6H4O2) was calculated using a bomb calorimeter with a total heat capacity of 7.854 kJ/°C. A 2.200 g sample was burned, resulting in a temperature increase from 23.50°C to 30.63°C. The heat of combustion per gram was determined to be 2.65 kJ/g, while the heat of combustion per mole was calculated to be 63.1 kJ/mol. These calculations are essential for understanding the energy release during the combustion of organic compounds.

PREREQUISITES
  • Understanding of calorimetry principles
  • Knowledge of heat capacity calculations
  • Familiarity with combustion reactions

I am needing help on some homework questions:

A 2.200 g sample of quinone, C6H4O2, is burned in a bomb calorimeter whose total heat capacity is 7.854 kJ/ degrees C. The temperature of the calorimeter increases from 23.50 degrees C to 30.63 degrees C.

1. What is the HEAT OF COMBUSTION PER GRAM of quinone? (in kJ/g)

2. Per mole of quinone? (in kJ/mol)

according to the rules in physics forum, we can't help those that didnt show their efforts. We are just guiding, not doing all the homework for you. you must at least show your way of calculations before we can help you.
