Question

In the following chemical reaction "zinc oxide reacts with carbon to produce zinc metal and carbon monoxide."

ZnO+C →Zn+CO

(i) Identify the substance getting oxidised and the one getting reduced.

(ii) State the reason for choosing the substances in (i).

(iii) Name the type of reaction and give another example of similar type of reaction.

Answer 1

(i) C is getting oxidized to CO, ZnO is getting reduced to Zn.

(ii) As carbon is gaining oxygen and ZnO, is losing oxygen.

(iii) It is a redox reaction or oxidation and reduction reaction.

CuO+H₂ → Cu+H₂O
