Originally Answered: Why do you think coal is not commonly used? Coal is commonly used but its use is decreasing. Coal is very dirty and also leaves behind difficult to dispose of material. Natural gas is much cheaper, easer to modulate (peaker plants), and is more environmentally friendly.

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.

How is coal formed?

Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Does coal make diamonds?

Over the years it has been said that diamonds formed from the metamorphism of coal. According to Geology.com, we now know this is untrue. “Coal has rarely played a role in the formation of diamonds. In fact, most diamonds that have been dated are much older than Earth’s first land plants – the source material of coal!
