Answer 2

i hope that after reading this u hav nt a single problem or query about coal.
Because of the various degrees of transformation that occurred during the forming of coal deposits in different locations, the composition of coal varies from one deposit to another. No two coals are the same in every respect. In general, coal consists of carbon, hydrogen, oxygen, nitrogen, sulfur and mineral matter (including compounds of silicon, aluminum, iron, calcium, magnesium and others).

Coal is also composed of organic elements called macerals.

The essence of the petrographic approach to the study of coal composition is the idea that coal is composed of macerals, which each have a distinct set of physical and chemical properties that control the behavior of coal.

There are three basic groups of macerals, the vitrinite group derived from coalified woody tissue, the liptinite group derived from the resinous and waxy parts of plants and the inertinite group derived from charred and biochemically altered plant cell wall material.

Answer 3

I have found a graph which shows coal has higher hydrogen content than wood...is that true..?

Answer 4

probably, seeing as how coal is lighter than wood
