The reaction between hydrofluoric acid (HF) and rubidium hydroxide (RbOH) is a neutralization reaction, producing a salt and water. Here's the balanced chemical equation:

HF (aq) + RbOH (aq) → RbF (aq) + H₂O (l)

Explanation:

* HF (aq): Hydrofluoric acid in aqueous solution.

* RbOH (aq): Rubidium hydroxide in aqueous solution.

* RbF (aq): Rubidium fluoride, a salt, in aqueous solution.

* H₂O (l): Water in liquid state.

The reaction is balanced because there are equal numbers of each type of atom on both sides of the equation.
