Q1: Hydrogen content of coke oven gas is __________ percent.

ANS:C - 58

"Hydrogen content of coke oven gas is 58 percent" is not accurate. Typically, coke oven gas contains a much lower percentage of hydrogen, ranging from 4 to 22 percent, as mentioned earlier. Coke oven gas is primarily composed of hydrogen (H2), methane (CH4), and carbon monoxide (CO), along with smaller amounts of other gases such as nitrogen (N2) and carbon dioxide (CO2). The hydrogen content in coke oven gas is relatively low compared to methane and carbon monoxide. Therefore, the statement suggesting a hydrogen content of 58 percent in coke oven gas is not accurate and does not align with typical compositions of coke oven gas.
