MCQ
When heated $N{H_3}$ is passed over $CuO$ gas evolved is
  • ${N_2}$
  • B
    ${N_2}O$
  • C
    $HN{O_3}$
  • D
    $N{O_2}$

Answer

Correct option: A.
${N_2}$
a
When ammonia is heated and passed over solid copper($II$)oxide at high temperatures, nitrogen gas is formed.

$2 NH _3( g )+3 CuO ( s ) \rightarrow N _2( g )+3 Cu ( s )+3 H _2 O ( g )$
