The enthalpies of combustion of carbon and carbon monoxide are as follows:

- The enthalpy of combustion of carbon (C) is approximately 394 kJ/mol.
- The enthalpy of combustion of carbon monoxide (CO) is approximately 283 kJ/mol.

These values represent the amount of heat released when one mole of the substance undergoes complete combustion with oxygen gas (O₂) to form carbon dioxide (CO₂) and water vapor (H₂O). The enthalpy of combustion is a measure of the energy content of a substance and is commonly used to calculate the heat released or absorbed during chemical reactions.
