Wirte the conjugate acids for the following Brdddotosted bases:
a. `overset(Θ)NH_(2)` b. `NH_(3)` c. `HCOO^(Θ)`

Explanation

To find the conjugate acids of the given Brønsted bases, we will follow the principle that a Brønsted base is a species that can accept a proton (H⁺). The conjugate acid is formed when the base accepts a proton.

### Step-by-Step Solution:

1. **Identify the first Brønsted base: `overset(Θ)NH_(2)` (NH₂⁻)**
- As a Brønsted base, NH₂⁻ can accept a proton (H⁺).
- When NH₂⁻ accepts H⁺, it forms NH₃ (ammonia).
- **Conjugate Acid:** NH₃

2. **Identify the second Brønsted base: `NH_(3)` (NH₃)**
- NH₃ can also act as a Brønsted base by accepting another proton (H⁺).
- When NH₃ accepts H⁺, it forms NH₄⁺ (ammonium ion).
- **Conjugate Acid:** NH₄⁺

3. **Identify the third Brønsted base: `HCOO^(Θ)` (HCOO⁻)**
- HCOO⁻ can accept a proton (H⁺) as a Brønsted base.
- When HCOO⁻ accepts H⁺, it forms HCOOH (formic acid).
- **Conjugate Acid:** HCOOH

### Final Answers:
- a. Conjugate acid of `overset(Θ)NH_(2)` is **NH₃**
- b. Conjugate acid of `NH_(3)` is **NH₄⁺**
- c. Conjugate acid of `HCOO^(Θ)` is **HCOOH**
