Final answer:
The balanced molecular equation for the reaction between hydrobromic acid (HBr) and rubidium hydroxide (RbOH) is HBr(aq) + RbOH(aq) → H2O(l) + RbBr(aq), representing an acid-base neutralization that produces water and rubidium bromide.
Step-by-step explanation:
To enter a balanced molecular equation for the reaction between hydrobromic acid and rubidium hydroxide, it's important to consider that this is an acid-base neutralization reaction. The reactants are hydrobromic acid (HBr) and rubidium hydroxide (RbOH). During the reaction, the H+ ion from the acid will combine with the OH− ion from the base to form water (H2O), and the remaining ions will form rubidium bromide (RbBr). The balanced equation for this reaction is:
Balanced Equation:
HBr(aq) + RbOH(aq) → H2O(l) + RbBr(aq)
Each reactant and product has one mole in the balanced equation, showing that the stoichiometric coefficients are all one, which implies the reaction is already balanced as written.
