    depends if in excess oxygen then P4O10 whose emperical formula is P2O5 so its the same but if in limited oxygen than P406 whose emperical formula is P2O3 so the same again so two different compounds are made actually so its a mixture of phosphates but in our syllabus it would be better if you...
