उत्तर
Aluminium metal does not react with water under ordinary conditions because of the presence of a thin (but tough) layer of aluminium oxide on its surface. Aluminium reacts with steam to form aluminium oxide and hydrogen gas.
\[\ce{\underset{Aluminium}{2Al_{(s)}} + \underset{Steam}{3H2O_{(g)}} -> \underset{Aluminium oxide}{Al2O3_{(s)}} + \underset{Hydrogen}{3H2_{(g)}}}\]
