Phosphorus pentoxide is a chemical compound with molecular formula P4O10 (with its common name derived from its empirical formula, P2O5). This white crystalline solid is the anhydride of phosphoric acid. It is a powerful desiccant and dehydrating agent. See more Phosphorus pentoxide crystallizes in at least four forms or polymorphs. The most familiar one, a metastable form (shown in the figure), comprises molecules of P4O10. Weak van der Waals forces hold these molecules … See more Phosphorus pentoxide is a potent dehydrating agent as indicated by the exothermic nature of its hydrolysis producing See more Phosphorus pentoxide itself is not flammable. Just like sulfur trioxide, it reacts vigorously with water and water-containing substances like wood or cotton, liberates much heat and may even cause fire due to the highly exothermic nature of such reactions. It is … See more P4O10 is prepared by burning white phosphorus with a sufficient supply of oxygen: P4 + 5 O2 → P4O10 The dehydration of phosphoric acid to give phosphorus pentoxide is not possible, as on heating it forms … See more Between the commercially important P4O6 and P4O10, phosphorus oxides are known with intermediate structures.

P stands for the chemical element phosphorus, from the periodic table. P is essential for the functioning of animals and plants; it is part of cells, as a building material and in DNA. WebDec 17, 2024 · As a consequence, a solution containing 75 % phosphoric acid can be made with 0.75 · 0.72.4 % = 54.3 % P X 2 O X 5. If now you want to dilute it to get a solution containing 4.7 % P X 2 O X 5, you have to take 4.7 / 54.3 = 8.65 % of your initial solution. fnf hellbeats mommy mearest
