Write the conjugate acids for the following Bronsted bases:

Bronsted base: A bronsted base is a substance that can accept a proton from an acid. A bronsted base is proton-acceptor.

When a base gain a proton, the residual part of it has a tendency to accept the proton. Therefore, it behaves as conjugate acid.

Conjugate base ⇌ Conjugate acid + H⁺ (gains proton)
