Determine the change in the oxidation number of S in `H_2S and SO_2` in the following industrial reaction:
`2H_2S(g) +SO_2 (g) rarr 3S (s) + 2H_2O(g)`

Explanation

To determine the change in the oxidation number of sulfur (S) in the reaction \(2H_2S(g) + SO_2(g) \rightarrow 3S(s) + 2H_2O(g)\), we need to analyze the oxidation states of sulfur in the reactants and products.

### Step 1: Determine the oxidation state of sulfur in \(H_2S\)

In \(H_2S\):
- Hydrogen (H) has an oxidation state of +1.
- Let the oxidation state of sulfur (S) be \(x\).
