Write a balanced equation for the combination reaction described, using the smallest possible integer coefficients. when diphosphorus pentoxide combines with water , phosphoric acid is formed.

P₂O₅ + 3H₂O => 2H₃PO₄

Explanation:

Nothing to explain.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
