The formula for Phosphorus(V) Oxide [which has 10 oxygen atoms in a molecule] is P4O10.
Phosphorus(III) oxide has the formula P2O3 but it exists as the molecule of P4O6
There are more than one of them, but the most common is P2O5.
HexaIodine DecaCarbide = I6C10
phosphorus pentaoxide or p2o5 dimerises into p4o10
OF2 is the formula for fluorine oxide.
Phosphorus(III) oxide has the formula P2O3 but it exists as the molecule of P4O6
The formula for Phosphorus(V) Oxide [which has 10 oxygen atoms in a molecule] is P4O10.
Phosphorus (III) oxide: P4O6
There are more than one of them, but the most common is P2O5.
You r question does not make sense, as it ends in 'and?'. However, Phosphorus oxide is usually named as 'phosphorus pentoxide. The formula being 'P2O5'. Phosphorus pentoxide often form the dimer 'P4O10',
Phosphorus pentoxide or phosphorus(V) oxide.
This equation is P4O10 + 6 H2O -> 4 H3PO4.
K2o *Remember the symbol for potassium is K and not P, which is phosphorus
HexaIodine DecaCarbide = I6C10
The chemical symbol for phosphorus oxide is P2O5.
The gram atomic mass of phosphorus is 30.9738, and that of oxygen is 15.9994. From the "Law of the Conservation of Mass", the amount of oxygen incorporated into the phosphorus oxide is 0.142 - 0.062 or 0.080 grams. The specified 0.062 grams of mass of phosphorus constitutes 0.062/30.973 or 2.00 X 10-3, to the (maximum possibly) justified number of significant digits, of Avogadro's Number of phosphorus atoms, and 0.080/15.9994 corresponds to 5.00 X 10-3 of Avogadro's Number of oxygen atoms. The ratio 5/2 does not reduce to any integral value; therefore, the empirical formula is P2O5.
The common name of this compound is phosphorus pentaoxide and the systematic name is Potassium(V) Oxide.
