The chemical reaction is:
2 SO2 + O2 ↔ 2 SO3
It is a compound.The chemical formula for sulphur dioxide is SO2. It is made of elements sulphur and oxygen. So it is a compound.
S+O2 ---> SO2 ( Sulphur Dioxide )
Yes, it is composed of three oxygen atoms and has the chemical formula O3.
Sulfur dioxide SO2 (written with two capitals)
S+O2 ---> SO2 ( Sulphur Dioxide )
O2 is the chemical formula for Oxygen. CO2 is the formula for Carbon Dioxide. (One Carbon, 2 Oxygen)
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).
Sulphur dioxide is made up of two(2) elements. They are Sulphur and Oxygen. They are both found in the Periodic Table. Their chemical combination is one sulphur(S) and two oxygens(O). Its chemical formula is 'SO2'. Their structural arrangement is 'O=S=O', That is each oxygen has a 'double bond to the sulphur. As the name suggests , it is ONE sulphur and TWO (oxygens ( di-oxide). It combines with water to form sulphurous acid (Note the spelling) H2SO3. NB For information there is also another sulphur/oxygen gas, viz. sulphur trioxide (SO3). This gas dissolves in water to form sulphuric acid (H2SO4) The chemical reaction equation is SO3 + H2O = H2SO4 .
When you burn sulphur with oxygen you create sulphur dioxide or sulphur trioxide.
Oxygen dichloride has OCl2 as its chemical formula.
Sulfur dioxide is a chemical compound, SO2, which is composed of one sulfur atom and two oxygen atoms.
"sulphur+oxygen->sulphur oxide."Se + O2 under pressure renders SeO2 (selenium dioxide). "Comment on the fact that the analagous reaction between sulphur and oxygen, although extremely slow, gives a product with a different stoichiometry". Part 1A Inorganic Chemistry Paper, University of Oxford, 2008.So the paper suggeststhat sulphur dioxide is not the product of direct combination of sulphur and oxygen. Why is this? Is it contaminated with some SO3?I think it's actually sulphur dioxide rather than sulphur oxide as someone else suggested. If you look at the reaction of carbon and oxygen, it doesn't produce carbon oxide, but carbon dioxide. So therefore I think if:Carbon + oxygen --> carbon dioxideThen:Sulphur + oxygen --> Sulphur dioxide
