Coal does not have a definite chemical composition; it is a complex mixture of organic compounds, primarily carbon, along with varying amounts of hydrogen, sulfur, oxygen, and nitrogen. The composition can significantly vary based on the type of coal (such as anthracite, bituminous, sub-bituminous, or lignite) and the geological conditions under which it formed. Additionally, impurities like minerals and moisture content can also influence its overall composition. As a result, coal is classified more by its properties and rank rather than a fixed chemical formula.
