Question

how coal gas produce...? teachers please tell me in short form

Answer 1

Ok I tell the answer but IAM not a teacher ok.

Coal gas, gaseous mixture—mainly hydrogen, methane, and carbon monoxide—formed by the destructive distillation (i.e., heating in the absence of air) of bituminous coal and used as a fuel. Sometimes steam is added to react with the hot coke, thus increasing the yield of gas.
