Question
Which of the following metal reacts with steam to produce oxide in place of hydroxide?
- Zinc
- Iron
- Magnesium
- Sodium
Hint:
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)
