Identify the species undergoing oxidation & reduction and oxidising agent & reducing agent in the reaction.
`I_(2)(g)+H_(2)S(g) rarr 2HI(g)+S(s)`

Explanation

To analyze the given reaction \( I_2(g) + H_2S(g) \rightarrow 2HI(g) + S(s) \) and identify the species undergoing oxidation and reduction, as well as the oxidizing and reducing agents, we can follow these steps:

### Step 1: Assign Oxidation States
First, we need to assign oxidation states to each element in the reactants and products.

- In \( I_2 \): Iodine (I) has an oxidation state of 0 (since it is in its elemental form).
- In \( H_2S \): Hydrogen (H) has an oxidation state of +1 and Sulfur (S) has an oxidation state of -2.
- In \( HI \): Hydrogen (H) has an oxidation state of +1 and Iodine (I) has an oxidation state of -1.
