It contains mostly methane, a simple chemical with the formula CH4. That means there are four hydrogen atoms for each carbon atom, the maximum a single carbon atom can accommodate. Coal’s chemical formula is far more complex (as we’ll see later).
What is the chemical formula of coal?
Coal is divided into four classes: anthracite, bituminous, sub-bituminous, and lignite. Elemental analysis gives empirical formulas such as C137H97O9NS for bituminous coal and C240H90O4NS for high-grade anthracite. Anthracite coal is a dense, hard rock with a jet-black color and a metallic luster.
What is the scientific name for coal?

What are 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.
What coal is used for?
The most significant uses of coal are in electricity generation, steel production, cement manufacturing and as a liquid fuel. Different types of coal have different uses. Steam coal – also known as thermal coal – is mainly used in power generation.
Is Coal still being formed?
The process of coal formation is still taking place today, says Bailey. “The precursor to coal is called peat, and that is just uncompressed plant matter.” Peat accumulates in wet swampy environments known as mires, and that process is taking place today in areas such as Indonesia and even the Antiplano in the Andes.
Why is coal bad for the environment?
