Coal is a non-renewable resource, so the supply can't produce faster than we can mine it.
Balanced chemical reaction:
4C₅H₉O + 27O₂ → 20CO₂ + 18H₂O.
According to principle of mass conservation, number of atoms must be equal on both side of chemical reaction.
Type of reaction is combustion.
Combustion is reaction with oxygen.
Organic compound reacts with oxygen and produce carbon dioxide and water.
