P₄ + 3 O₂ → 2 P₂O₃
Explanation:
Phosphorous (P₄) will react with oxygen (O₂) to produce phosphorus trioxide (P₂O₃):
P₄ + O₂ → P₂O₃
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each element leaving the reaction, in order to conserve the mass.
The balanced chemical equation is:
P₄ + 3 O₂ → 2 P₂O₃
