(a)Write the conjugate acids for the following Bronsted bases :
`NH_2^(-) , NH_3` and `HCOO^-`
(b)Write the conjugate bases for the following Bronsted acids :
`HF, H_2SO_4 , HCO_3^-`

Explanation

To solve the given question, we need to identify the conjugate acids of the provided Bronsted bases and the conjugate bases of the provided Bronsted acids.

### Part (a): Conjugate Acids of Bronsted Bases

1. **Identify the Bronsted Bases**: The bases given are `NH2^(-)`, `NH3`, and `HCOO^(-)`.

2. **Determine the Conjugate Acid**:
- For `NH2^(-)`:
