Phosphorus reacts with oxygen to form diphosphorus pentoxide (P2O5). The balanced chemical equation for this reaction is 4P(s) + 5O2(g) → 2P2O5(s). The reaction between phosphorus and oxygen is an example of oxidation, where one reactant is oxidized by another. When phosphorus reacts with a limited supply of oxygen, it forms phosphorus (III) oxide, P4O6: P4(s) + 3O2(g) → P4O6(s) When phosphorus reacts with excess oxygen, it forms phosphorus (V) oxide, P4O10: P4(s) + 5O2(g) → P4O10(s) Hope fully everyone understands 😅😅
