Answer 1

A-Na,B-H20,C-SO2,D-H2SO3

Answer 2

Below are the answers marked infront of the reactions.

The following equation is given: H2S + Cl2 S + 2HCl (1) Oxidized material

H2S is the answer.

H2S is oxidised to generate S by losing hydrogen atoms.

(2) Substance reduction

Cl2 is the answer.

Cl2 is converted to HCl by acquiring hydrogen atoms.

(3) The oxidizer

Cl2 is the answer.

The reduced material is referred to as an oxidising agent. As a result, Cl2 is an oxidising agent.

(4) The agent that reduces.

H2S is the answer.
