Question

Complete the following reaction:
$2{\mathrm{NH}}_3+3\mathrm{CuO}\to$

• A. $\mathrm{Cu}+H_2+{\left(\mathrm{NO}\right)}_2$
• B. $3\mathrm{Cu}+3H_{2}O+N_2$
• C. $\mathrm{CuO}+H_2+N_2$
• D. $3\mathrm{Cu}+3H_{2}O+N_2$

Answer 1

The correct option is B $3\mathrm{Cu}+3H_{2}O+N_2$

Ammonia reduces heated metal oxides to the respective metals. In the process water and nitrogen is released. The complete reaction is:
$2{\mathrm{NH}}_3+3\mathrm{CuO}\to 3\mathrm{Cu}+3H_{2}O+N_2$
