The reaction between hydrobromic acid (HBr) and water (H2O) can be expressed as follows:
\[ \text{HBr}(aq) + \text{H}_2\text{O}(l) \rightarrow \text{H}_3\text{O}^+(aq) + \text{Br}^-(aq) \]
The products of the reaction are hydronium ions (H3O⁺) and bromide ions (Br⁻).
Now, let's put this in the requested balanced equation format with the appropriate states:
\[ \text{HBr}(aq) + \text{H}_2\text{O}(l) \rightarrow \text{H}_3\text{O}^+(aq) + \text{Br}^-(aq) \]
This equation is balanced with respect to both mass and charge.
