This is an incomplete question, here is a complete question.

For each reaction, identify the Bronsted-Lowry acid, the Bronsted-Lowry base, the conjugate acid, and the conjugate base.

$HBr(aq)+H_2O(l)\rightleftharpoons H_3O^+(aq)+Br^-(aq)$

Express your answers as a chemical expressions. Enter your answers in order given in the question separated by commas.

Answer : The given equilibrium reaction will be,

$HBr(aq)+H_2O(l)\rightleftharpoons H_3O^+(aq)+Br^-(aq)$

Acid Base Conjugate Conjugate

acid base

Explanation :

According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.

Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor.

The given equilibrium reaction will be,

$HBr(aq)+H_2O(l)\rightleftharpoons H_3O^+(aq)+Br^-(aq)$

Acid Base Conjugate Conjugate

acid base

In this reaction, $HBr$ is an acid that donate a proton or hydrogen to $H_2O$ base and it forms $Br^-$ and $H_3O^+$ are conjugate base and acid respectively.
