Arrange the acids `H_2SO_4,H_2SeO_4` and `H_2TeO_4` in decreasing order of their strength.

Explanation

To arrange the acids \( H_2SO_4 \), \( H_2SeO_4 \), and \( H_2TeO_4 \) in decreasing order of their strength, we can follow these steps:

### Step 1: Identify the acids and their corresponding central atoms
The acids in question are:
- \( H_2SO_4 \) (sulfuric acid)
- \( H_2SeO_4 \) (selenic acid)
- \( H_2TeO_4 \) (telluric acid)
