Solution

The correct answer is (1) Carbon monoxide and hydrogen. Both coal gas and water gas contain these two gases.

Here's a step-by-step explanation:

  1. Coal gas is produced by the destructive distillation of coal. It is a gaseous fuel that was widely used during the 19th and early 20th centuries. The primary components of coal gas are hydrogen (50%), methane (35%), and carbon monoxide (10%).

  2. Water gas is a synthesis gas, which is a mixture of carbon monoxide and hydrogen. It is produced from steam and a carbon source, such as coal. The reaction is as follows: C (s) + H2O (g) → CO (g) + H2 (g).

So, both coal gas and water gas contain carbon monoxide and hydrogen.
