Web1 day ago · Phosphor bronze has an impressive yield strength, matching some aluminum alloys and surpassing even other bronzes, and this is thanks to its high percentage of tin and phosphorus. When combined with its good spring characteristics, this creates an alloy that is strong and will stay strong. Modulus of elasticity, or Young's modulus, describes ... 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 phosphoric acid: P4O10 + 6 H2O → 4 H3PO4 (–177 kJ) However, its utility for drying is limited somewhat by its … See more Phosphorus pentoxide itself is not flammable. Just like sulfur trioxide, it reacts vigorously with water and water-containing … 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. On observation it will be seen that double bonded oxygen in at … See more • Eaton's reagent See more
