When steam is passed over red-hot carbon, the substances produced are
- Hydrogen and trioxocarbonate (IV) acid
- Hydrogen, oxygen and carbon (IV) oxide
-
Hydrogen and carbon (II) oxide
- Hydrogen and carbon (IV) oxide
The correct answer is: C
Explanation
Water gas is produced when steam is passed over red-hot carbon. Water gas has the chemical formula as CO + H\(_2\)
The chemical reaction for the production of water gas is C(s) + H\(_2\)O(g) → CO(g) + H\(_2\)(g).
