Answer
- Sodium reacts vigorously with cold water to form sodium hydroxide and hydrogen gas 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g) + Heat
- Magnesium reacts with water to form magnesium hydroxide and Mg(s) + 2H2O(l) → Mg(OH)2(aq) + H2(g)
- Aluminum reacts with steam to form aluminium oxide and hydrogen gas 2Al(s) + 3H2O(g) → Al2O3(s) + 3H2(g)
