21. However, dinitrogen pentoxide in liquid or gaseous state is molecular and does not contain nitronium ions. 22. As an alternative for small-scale production, vanadium pentoxide is reduced with hydrogen or magnesium. 23. "' Phosphorus pentoxide "'is a chemical compound with molecular formula dehydrating agent. 24. In a variation the reaction of phenols and beta-ketoesters and phosphorus pentoxide yields a chromone. 25. In 1933, Frandsen conducted research on the " Heat Capacity of Phosphorus Pentoxide ". 26. This is then melted to form a crude form of vanadium pentoxide ( V 2 O 5 ). 27. The permittivity of tantalum pentoxide is approximately three times higher than aluminium oxide, producing significantly smaller components. 28. :You maight want to take a look at phosphorus pentoxide : it reacts highly exothermically with water. 29. :The phosphorus is first oxidised to P _ 4 O _ { 10 }, Phosphorus pentoxide . 30. A solution of vanadium ( V ) perchlorate can be made by dissolving vanadium pentoxide in perchloric acid.
