Write the chemical equation for the reaction taking place when steam is passed over hot aluminium.

(N/A) When steam is passed over hot aluminium,it reacts to form aluminium oxide and hydrogen gas.
The balanced chemical equation for this reaction is:
$2Al(s) + 3H_2O(g) \rightarrow Al_2O_3(s) + 3H_2(g) \uparrow$
In this reaction,aluminium metal reacts with steam (gaseous water) at high temperatures to produce aluminium oxide and hydrogen gas.
