when placed in aqueous solution, hbr gas becomes:

Explanation:

Step1: Recall acid - dissociation in water

When a strong acid like HBr is placed in an aqueous solution, it dissociates completely. The chemical equation for the dissociation of HBr in water is $HBr(aq)+H_2O(l)
ightarrow H_3O^+(aq) + Br^-(aq)$. In an aqueous solution, HBr gas forms hydronium ions ($H_3O^+$) and bromide ions ($Br^-$).

Answer:

A solution containing $H_3O^+$ and $Br^-$ ions.
