State the relevant observation for the following:

Water is added to the product formed, when Al is burnt in a jar of nitrogen gas.

Answer 1

Pungent, alkaline gas is evolved. Urinals and stables often smell of this gas.

\[\ce{2Al + N2 -> \underset{[Burning of aluminium]}{2AlN}}\]

\[\ce{AlN + 3H2O -> \underset{[Pungent gas]}{Al(OH)3} + NH3↑}\]
