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: H₂O, HCO₃⁻, HSO₄⁻, and NH₃.

### Step-by-Step Solution:

1. **Identify the first species: H₂O (Water)**
- **As a Bronsted Acid:** Water can donate a proton (H⁺) to become OH⁻ (hydroxide ion).
- **Conjugate Base:** OH⁻
- **As a Bronsted Base:** Water can accept a proton (H⁺) to become H₃O⁺ (hydronium ion).
