Predict the relative acidic strength among the following:
`H_(2)O`, `H_(2)S`, `H_(2)Se`, `H_(2)Te`.

Explanation

To predict the relative acidic strength among the compounds \( H_2O \), \( H_2S \), \( H_2Se \), and \( H_2Te \), we need to analyze the stability of their conjugate bases after they lose a proton (H\(^+\)). The conjugate bases formed will be \( OH^- \), \( HS^- \), \( HSe^- \), and \( HTe^- \) respectively.

### Step-by-Step Solution:

1. **Identify the Conjugate Bases**:
- When each acid donates a proton, the following conjugate bases are formed:
- From \( H_2O \): \( OH^- \)
- From \( H_2S \): \( HS^- \)
