Sulphur and Oxygen
You don't say that. What you do say is that the valency of sulphur in sulphur trioxide is 6.
Yes, it is
Sulphur dioxide, Sulphur trioxide...
When you burn sulphur with oxygen you create sulphur dioxide or sulphur trioxide.
sulfur and oxygen SO3
The difference between sulphur dioxide and sulphur trioxide is that there are 2 molecules of oxygen present in sulphur dioxide (SO2) and there are 3 molecules of oxygen are present in sulphur trioxide (SO3).
Sulfur (sulphur) dioxide and sulfur trioxide all are compounds, as ANY oxide is.
Sulfur tetraoxide 2- SO4 is sulfate
what element contains 16 protons? what element contains 10 protons?
As the name implies, its constituent elements are sulfur and oxygen. Sulfur trioxide has the formula SO3, which means it contains one sulfur atom and three oxygen atoms.
anitmony (II) trioxide
If, by your slightly jumbled question, you meant "What compounds are the element of sulphur in?", then Sulphur trioxide, Sulphuric acid and the sulphates, sulphur hexafluoride, toxic solvent carbon disulphide, metal sulphides and the other oxides of sulfur which are formed by incomplete combustion; sulphur monoxide and sulphur dioxide.
