  • 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.

    CO 2 is also the main byproduct of coal combustion: nearly 4 grams of CO2 are produced for every gram of carbon burnt (depending on its type, coal can contain as much as 60 to 80 percent carbon). Methane (CH4) often occurs in the same areas that coal is formed, and is released during mining activities.
