Coal is composed of the remains of what organisms? Coal: Coal is black sediment that deposits in the coal seams in the form of rocks. Coal contains large amounts of carbon, and it also contains a ...
2021-1-14 Coal is a sedimentary rock made predominantly of carbon that can be burned for fuel. Coal is readily combustible, black or brownish-black, and has a composition that, including inherent moisture, consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material. It is formed from plant remains that have been compacted, hardened, chemically
quot;The classification of coal is generally based on the content of volatiles. However, the exact classification varies between countries. According to the German classification, coal is classified as follows: Name Volatiles % C Carbon % H Hydrogen % O Oxygen % S Sulfur % Heat content kJ/kg Braunkohle (Lignite) 45-65 60-75 6.0-5.8 34-17 0.5-3 ...

Coal is considered a type of sedimentary rock that is black or brown in color and is combustible. It is for this reason that coal is widely used as a fossil fuel for generation of electric power in many countries across the globe. But before coal solidified into a rock form, the plant remains were said to be free from oxidation and biodegradation.
2 天前 Coal is a combustible, sedimentary, organic rock, which is composed mainly of carbon, hydrogen and oxygen. It is formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams.
Coal - Coal - Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins. As peat formation and coalification proceed, these compounds, which have more or less open structures, are broken down, and new compounds—primarily aromatic (benzenelike) and hydroaromatic ...
