Answer 1

Hi friend,

Here's your answer,

A combustible gas obtained by the destructive distillation of coal is COAL GAS


•Destructive Distillation-

Destructive distillation is the chemical process of the decomposition of feedstock by heating it to a high temperature; the term generally applies to processing of organicmaterial in the absence of air or in the presence of limited amounts of oxygen or other reagents, catalysts, or solvents, such as steam or phenols. It is an application of pyrolysis. The process breaks up or 'cracks'large molecules. Coke, coal gas, gas carbon, coal tar, ammonia liquor, and "coal oil" are examples of commercial products historically produced by the destructive distillation of coal.


•Coal Gas-

A mixture of gases (chiefly hydrogen, methane, and carbon monoxide) obtained by the destructive distillation of coal and formerly used for lighting and heating.
