(C) The chemical reaction is: $2NH_3 + 3CuO \xrightarrow{\Delta} N_2 + 3Cu + 3H_2O$. In this reaction,the oxidation state of nitrogen increases from $-3$ to $0$ (oxidation),and the oxidation state of copper decreases from $+2$ to $0$ (reduction). Since ammonia reduces copper oxide to metallic copper,it acts as a reducing agent.

When ammonia is passed over heated copper oxide,metallic copper is obtained. This reaction shows that ammonia is a.......
