What is the end product of coal?
Coal is currently a major source of fuel for power generation, industrial heat, and, on a smaller scale, manufacture of coke and by-product coal tar.

What products are made from coal?
Thousands of different products have coal or coal by-products as components: soap, aspirins, solvents, dyes, plastics and fibres, such as rayon and nylon.
What are the two by products of coal?
1)When coal is heated in the absence of air,then coal gas and coal tar are eliminated,and coke is left behind as a black residue. 2)Coke is an almost pure form of carbon.It is 98% carbon. 3)It is mainly used as a reducing agent in the extraction of metals.
What chemical is released from coal?
Carbon dioxide (CO2), which is the primary greenhouse gas produced from burning fossil fuels (coal, oil, and natural gas)
What are the 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.
Is coal still being formed?
Coal is very old. The formation of coal spans the geologic ages and is still being formed today, just very slowly. Below, a coal slab shows the footprints of a dinosaur (the footprints where made during the peat stage but were preserved during the coalification process).
What are disadvantages of using coal?
The major disadvantage of coal is its negative impact on the environment. Coal-burning energy plants are a major source of air pollution and greenhouse gas emissions. In addition to carbon monoxide and heavy metals like mercury, the use of coal releases sulfur dioxide, a harmful substance linked to acid rain.
Why is coal still used?
The single largest source of greenhouse gas emissions is coal-fired electricity generation, and two-thirds of the world’s coal is used to produce electricity. (Most of the rest is used to make iron and steel.)
How is coke obtained from coal?
Coke is obtained by destructive distillation of charcoal or coal in the furnace Destructive distillation is the chemical process involving the decomposition of coal or charcoal by heating to a high temperature in the absence of air or in the presence of limited amounts of oxygen.
