The species: `H_(2)O, HCO_(3)^(Θ), HSO_(4)^(Θ)` and `NH_(3)` can act both as Bronsted acids and bases. For each case give the corresponding conjugate acid and base.

Explanation

To solve the problem, we need to identify the conjugate acids and bases for each of the given species: \( H_2O \), \( HCO_3^- \), \( HSO_4^- \), and \( NH_3 \).

### Step-by-Step Solution:

1. **Identify the Species**:
- The species we are considering are:
- \( H_2O \) (water)
- \( HCO_3^- \) (bicarbonate ion)
