Vedclass · Answer

(A) When ammonia is heated and passed over solid copper$(II)$ oxide $(CuO)$ at high temperatures,it acts as a reducing agent and reduces $CuO$ to metallic copper,while ammonia itself is oxidized to nitrogen gas.The balanced chemical equation is:$2 NH_{3(g)} + 3 CuO_{(s)} \rightarrow N_{2(g)} + 3 Cu_{(s)} + 3 H_2O_{(g)}$Thus,the gas evolved is $N_2$.

When heated $NH_3$ is passed over $CuO$,the gas evolved is:
