What Is the Chemical Equation for the Combustion of Coal ...

The chemical equation for the combustion of coal is C + O2 = CO2. In this equation, C represents the carbon in the coal, which reacts with air, represented by O2, to form carbon dioxide, or CO2. When coal combustion occurs in an environment low on oxygen, the equation C + CO2 = 2CO may result.
