SUMMARY
The heat of combustion for glucose (C6H12O6) is calculated to be approximately -2813 kJ/mole. To derive this value, one must first write the balanced chemical equation for the combustion of glucose, which involves determining the number of bonds broken and formed during the reaction. Utilizing bond energies from reliable sources, the calculation follows the formula: ΔH of reaction = Bonds broken (reactants) - Bonds formed (products). This method provides a clear pathway to arrive at the heat of combustion value.
