Answer 2

Answer

$\sf H_2O$ is reduced and C is oxidised.

$\rule{200}1$

Explanation

Given reaction

$\sf H_2O(g) + C(s) \rightarrow H_2(g) + CO(g)$

Here, since oxygen is being removed from water, water is reduced to hydrogen gas.

Also, since oxygen is being added to carbon, carbon is oxidised to carbon monoxide.

Oxidation

→ Loss of electron

→ Addition of oxygen

→ Removal of hydrogen

→ Addition of electronegative element

→ Gain in oxidation number

Reduction

→ Gain of electrons

→ Removal of oxygen

→ Addition of hydrogen

→ Addition of electropositive element

→ Loss in oxidation number

★ Substance which is oxidised acts as reducing agent as it oxidises itself to reduce others.

★ Substance which is reduced acts as oxidising agent as it reduces itself to oxidise others.
