Answer:
Explanation:
Sodium is a highly reactive metal which even reacts with cold water violently. the reaction is so violent and exothermic that the evolved hydrogen immediately catches fire.
2Na(s) + 2H2O (l) -------> 2NaOH (aq) + H2 + heat energy
Metals like aluminium neither react with cold water or hot water but react with steam to forma metal oxide and hydrogen gas.
2Al (s) + 3H2O (l) -------------> Al2O3 (aq) + 3H2 (g)
