1. When iodic acid is carefully heated, it dehydrates to iodine pentoxide . 2. Common dehydrating agents include phosphorus pentoxide , anhydrides, or zinc chloride. 3. Reduction of vanadium pentoxide with calcium gives pure vanadium. 4. *The reaction of phosphorus pentachloride ( ) with phosphorus pentoxide ( ). 5. The main oxide of phosphorus is called " phosphorus pentoxide ". 6. However, at conditions most common for burning, vanadium pentoxide gets formed. 7. In general tantalum pentoxide is considered to be a high-k dielectric material. 8. The semiconducting form is rich on vanadium pentoxide . 9. Vanadyl nitrate can also be made from vanadyl trichloride VOCl 3 and dinitrogen pentoxide . 10. Molecules within the Td point group include methane, phosphorus pentoxide , and adamantane.
