Ribose has 10 hydrogens and 5 oxygens.
The correct name for N2O5 is dinitrogen pentoxide.
P2O5: Phosphorus Pentoxide CO: Carbon Monoxide
The chemical formula for tetraphosphorus pentoxide is P4O10.
Diarsenic pentoxide is a covalent compound.
Ribose has 10 hydrogens and 5 oxygens.
because the arrangement of the oxygens in the crystal structure sets the energy difference between a molecular orbital energy level and its excited state to correspond to that wavelength of light. If you change the orientation of the oxygens, change the number of oxygens or change the ligands to something altogether different, the difference in molecular orbital energy levels will also change. The new energy difference will correspond to a new color.

The compound name for P2O5 is diphosphorus pentoxide.
The correct name for N2O5 is dinitrogen pentoxide.
P2O5: Phosphorus Pentoxide CO: Carbon Monoxide
The correct name for P2O5 is diphosphorus pentoxide. This compound is composed of two phosphorus atoms and five oxygen atoms. The prefix "di-" indicates the presence of two phosphorus atoms, while the suffix "-pentoxide" indicates the presence of five oxygen atoms.
The chemical symbol for diphosphorus pentoxide is P4O10.
Dihydrogen pentaoxide would mean 2 hydrogens and 5 oxygens, or H2O5. This would be an exceedingly unstable molecule, since two hydrogen atoms normally combine with only one oxygen atom, not five.
The molecular formula for dinitrogen pentoxide is N2O5. This means that each molecule contains 2 nitrogen atoms and 5 oxygen atoms.
IO2 is the chemical formula of iodine dioxide.
