Question

Which of the following metal reacts with steam to produce oxide in place of hydroxide?

  1. Zinc
  2. Iron
  3. Magnesium
  4. Sodium

hintHint:

Magnesium reacts with steam to produce magnesium oxide and hydrogen gas.

The correct answer is: Magnesium


    Magnesium react with steam to produce white magnesium oxide and hydrogen gas. This is because the metal hydroxides thermally decompose to the oxide and water.
    Mg(s) + H2O(g) ---> MgO(s) + H2(g)
