Water gas is a mixture of

  • A.carbon dioxide and hydrogen
  • B.carbon monoxide and hydrogen
  • C.methane and hydrogen
  • D.carbon monoxide and nitrogen

Answer: B

Steam passed over incandescent coke gives the two gases in roughly equal volumes by an endothermic reaction, so the bed cools and the blast must be alternated with air. Both constituents burn, which is why its calorific value is respectable.
