What is the action of water on (a) sodium (b) magnesium and (c) aluminium? Write equations of the chemical reactions involved.
(a) Sodium reacts vigorously with cold water to form sodium hydroxide and hydrogen gas
The equation for the reaction is given below:
$2Na(s) + 2H_2O(l) → 2NaOH(aq) + H_2(g) + Heat$
(b) Magnesium reacts with water to form magnesium hydroxide and hydrogen.
The equation for the reaction is given below:
$Mg(s) + 2H_2O(l) → Mg(OH)_2(aq) + H_2(g)$
(c) Aluminum reacts with steam to form aluminum oxide and hydrogen gas
The equation for the reaction is given below:
$2Al(s) + 3H_2O(g) → Al_2O_3(s) + 3H_2(g)$
