Phosphorus(III) oxide has the formula P2O3 but it exists as the molecule of P4O6
The formula for sulphur IV oxide is SO2.
The formula for sulphur vi oxide is SO3.
SOx is the formula for sulphur oxide's. A common example is sulphur dioxide S02.
A Molecule consists of one or more atoms so yes, sulphur di oxide is a molecule.
A Nitro group when attached to an organic molecule. Alone it is Nitric Oxide
The formula for Phosphorus(V) Oxide [which has 10 oxygen atoms in a molecule] is P4O10.
The chemical formula for aluminum oxide dihydrate is Al2O3•2H2O. This formula indicates that there are two water molecules associated with each aluminum oxide molecule.
The chemical formula for boron oxide is B2O3
The chemical formula for silver(I) oxide is Ag2O.The chemical formula for silver(II) oxide is AgO.
Al2O3 is the chemical formula of aluminium oxide.
SO3 Tetra means four, genius. SO3 is Sulphur Trioxide. Sulphur Tetroxide exists as an anion [SO4]2- More commonly referred to as a sulphate. Sulphur Tetroxide is not sulphate, sulphate is an ion while Sulphur Tetroxide is not just like sulphur trioxide (SO3) is a neutral molecule whereas sulphite (SO3)2- is an ion...... so yes, sulfur tetraoxide is SO4, nothing more nothing less
