Схема перетворення S -> SO2 -> SO3 -> H2SO4 -> BaSO4

1. Sulfur (S) to Sulfur Dioxide (SO2): - Sulfur can be converted to sulfur dioxide through the combustion of sulfur in the presence of oxygen. - The chemical equation for this reaction is: S + O2 -> SO2. - Sulfur dioxide is a colorless gas with a pungent odor and is commonly produced during the burning of fossil fuels and the smelting of metal ores.

2. Sulfur Dioxide (SO2) to Sulfur Trioxide (SO3): - Sulfur dioxide can be further oxidized to sulfur trioxide through the contact process. - In the contact process, sulfur dioxide is reacted with oxygen in the presence of a catalyst, usually vanadium pentoxide (V2O5), at high temperatures. - The chemical equation for this reaction is: 2SO2 + O2 -> 2SO3. - Sulfur trioxide is a colorless liquid or solid that is highly reactive and can react with water to form sulfuric acid.

3. Sulfur Trioxide (SO3) to Sulfuric Acid (H2SO4): - Sulfur trioxide can react with water to form sulfuric acid. - The chemical equation for this reaction is: SO3 + H2O -> H2SO4. - Sulfuric acid is a strong acid that is widely used in various industries, including the production of fertilizers, dyes, detergents, and batteries.

4. Sulfuric Acid (H2SO4) to Barium Sulfate (BaSO4): - Sulfuric acid can react with barium chloride (BaCl2) to form barium sulfate. - The chemical equation for this reaction is: H2SO4 + BaCl2 -> BaSO4 + 2HCl. - Barium sulfate is a white crystalline solid that is insoluble in water and commonly used as a contrast agent in medical imaging procedures, such as X-rays and CT scans.

Please note that the reactions mentioned above are simplified representations of the actual chemical processes involved. The conditions, catalysts, and specific reaction mechanisms may vary depending on the industrial processes used.
