Yes, it is composed of three oxygen atoms and has the chemical formula O3.
Sulphur powder is a pure substance.
Yes, unless it is contaminated.
Carbon dioxide is a pure substance that is a compound.
Sulfur is an element. Elements are not mixtures.
Sulphur can be pure or impure depending on it's source.For that matter no substance can be classified as pure or impure just by it's name.It depends on what chemists call ASSAY.Whenever you buy a chemical ask for ASSAY,you will know it's purity.Sometimes , even if the purity is not 100%,the chemical can be used if the impurity does not affect the product.Even the so called pure metals will have some amount of impurity

Carbon dioxide (CO2) is a compound and can be also a pure substance.

No, SO2 is a pure substance. It is a chemical compound composed of sulfur and oxygen in a fixed ratio.
Sulphur , in a form of sulphur dioxide or sulphur oxide , I think. Acid rain can be caused by either nitric oxide or sulfur dioxide in the air, which result from the burning of fossil fuels.
For a substance to be pure, it must have no impurities in the substance. Carbonated water is water with carbon dioxide and other substances dissolved in this. Hence, it is not a pure substance.
Silicon dioxide is a pure substance. It is a chemical compound made up of silicon and oxygen atoms in a fixed ratio, with a specific chemical formula (SiO2).
No, sulfur is an element and sulfur dioxide is a gaseous compound. Sulfur dioxide is the combustion product of sulfur in an oxygen atmosphere (S+O2 --> SO2) Where sulfur is an element, sulfur dioxide is a compound and where sulfur is an insoluble yellow solid, sulfur dioxide is a colorless soluble gas.
