What are the correct formulas and coefficients for the products of this double-replacement reaction? rboh + h3po4 → rb3po4 + 3h2o rbpo4 + 2h2o rb (po4) 3 + h2o h3rb + po4oh?

Answer is: Rb₃PO₄ + 3H₂O.

Reaction: 3RbOH + H₃PO₄ → Rb₃PO₄ + 3H₂O.

RbOH - r ubidium hydroxide, base.

H₃PO₄ - orthophosphoric acid.

Rb₃PO₄ - rubidium-phosphate.

H₂O - water.

This type of reaction is called neutralisation.

Neutralisation is a chemical reaction in which an acid and a base react with each other.
