ZnO when heated with Carbon at 1000°C is reduced to Zn metal and CO(g) is evolved. Write a balanced reaction and underline the reducing agent.
Zine oxide reacts with carbon, on heating, to form zinc metal and carbon monoxide. Write a balanced chemical equation for this reation. Name (i) oxidising agent, and (ii) reducing agent, in this reaction.
When ammonia gas is passed over heated CuO,nitrogen gas is evolved from another end. Write a balanced chemical reaction to showcase the above redox change and specify the change of color, if any. Also, specify the oxidizing and reducing agents in the above reaction.
