Question
Write observations: Ammonia gas is passed over heated copper (ll) oxide.
✓

Answer

When gaseous ammonia is passed over solid copper(II)oxide at high temperatures, nitrogen gas is formed.
$
2 NH _{3( g )}+3 CuO _{( s )} \longrightarrow N _{2( g )}+3 Cu _{( s )}+3 H _2 O _{( g )}
$
Also This $N_2$ gas is not pure as it would be in the heating of $NaN _3$ like compounds.
