pure substance
The pure substance of sulfur hexafluoride consists of a single type of molecule made up of one sulfur atom and six fluorine atoms bonded together. It is a colorless, odorless gas that is non-flammable and non-reactive under normal conditions.
It can be, as long as no other substances are present.
The way you phrase that is a little dubious because no mixture is a 'pure substance'. However, compounds like iron sulphide that are actually bonded together areconsidered pure substances. The elements of a mixture are not united by a chemical change and can (in theory) be separated.
No coal is a mixture of carbon and organic compounds.
Sulfur trioxide is a compound with a chemical formula SO3, consisting of sulfur and oxygen atoms. It is a homogeneous substance because it is a pure compound with uniform composition throughout.
A pure substance is a substance that is constant throughout. Such as water, tin or sulfur.
No. Sulfur dioxide is a compound, which makes it a pure substance, not a mixture.
Sulfur is not a mixture at all. It is a pure substance. Specifically it is an element.
Pure substance can be identified as either elements or compounds. Some examples of pure substance that are elements are sulfur and tin. Pure substances that are compounds are sugar and salt.

Yes, it is the compound Sulfur trioxide. Hint: If it has a chemical formula (with no + or - at the end) it is a pure substance.
It can be, as long as no other substances are present.
A pure substance is classified by having a definite and constant composition. The substance can be either an element or a compound, but what makes the substance pure, is that it does not vary.
Sulfur is an element. Elements are not mixtures.
Sulfur is an element. Elements are not mixtures.
A pure substance has only one kind of particle. Sulfur is an example of a pure substance.
