For phosphorus trioxide, P2O3 formula unit, P4O6 molecular formula
P3n1s
(po4)3o2
So2
The molecular formula of carbon dioxide is CO2
Triphosphorus monoxide
Molecular
Triphosphorus Pentanitrite
Trisodium Phosphate = Na3PO4 It contains Na+ and PO4-3 ions.
The molecular formula of carbon dioxide is CO2
Triphosphorus monoxide
Molecular
Polonium dioxide - PoO2
TiO2
CO2 is the molecular formula of carbon dioxide and O3 is the molecular formula of ozone.
Triphosphorus Pentanitrite
Trisodium Phosphate = Na3PO4 It contains Na+ and PO4-3 ions.
Any dioxide has two (= 'di-') oxygen atoms (= 'oxide') in its molecular formula. Examples: Carbon dioxide CO2 and Sulfur dioxide SO2
SO2 is the molecular formula for sulfur dioxide. SO2 is a toxic gas with rotten, irritating and pungent smell. Volcanic eruption will lead to release of SO2 into the atmosphere.
The empirical formula for nitrogen dioxide is the same as its molecular formula - NO2. See related question below for more details on how to find empirical formulas.
P3Br6, (an imaginary compound set as a test I hope!)
