# How do you write the equation for the following reaction: solid diphosphorus pentaoxide reacts with water to form phosphoric acid?

${P}_{4} {O}_{10} + 6 {H}_{2} O \left(l\right) \rightarrow 4 {H}_{3} P {O}_{4} \left(a q\right)$
Is this stoichiometrically balanced? ${P}_{4} {O}_{10}$ is the so-called $\text{anhydride}$ of phosphoric acid.
