Respuesta :

Phosphoric acid and hydrogen fluoride are the products of the  chemical reaction between phosphorus pentafluoride and water.

PF5(g)+H2O(l)→H3PO4(aq)+HF(g)

The equation is already balanced. So we don't need to balance this equation.

When each element in a chemical reaction has the same number of atoms and total charge on both the reactants and products sides of the equation, the reaction is said to be balanced. In other words, both sides of the reaction have an equal mass and charge of the components. because a chemical reaction is simply an arrangement of the atoms of the supplied elements, a chemical equation must be balanced. In order to adhere to the law of conservation of mass, the chemical equation must be balanced.
