Question

The reducing agent used in the reduction of zinc oxide to zinc is:

• A. Pure zinc
• B. Carbon monoxide
• C. Coke
• D. Carbon dioxide

Answer 1

The correct option is C Coke

Zinc oxide (ZnO) is reduced to zinc by using reducing agents. Coke (C) is used as a reducing agent for this process.

The reaction is as follows:

$\text{ZnO(s)}+\text{C(g)}\stackrel{{1400}^{\circ }C}{\to }\text{Zn(s)}+\text{CO(g)}$
