Answer 1

S —› SO2 —› SO3 —› H2SO4 —› BaSO4.

1) S + O2 —› SO2

2) 2SO2 + O2 —› 2SO3

3) SO3 + H2O —› H2SO4

4) H2SO4 + BaCO3 —› BaSO4↓ + H2CO3

Answer 2

It looks like you've provided a list of chemical compounds related to sulfur and its compounds. Let me provide some information about each of them:

1. SO2 (Sulfur Dioxide): Sulfur dioxide is a chemical compound composed of one sulfur atom and two oxygen atoms. It is a colorless gas with a pungent smell. SO2 is produced primarily by burning fossil fuels, such as coal and oil, and is a common component of air pollution. It can also be found in volcanic emissions.

2. SO3 (Sulfur Trioxide): Sulfur trioxide is a chemical compound consisting of one sulfur atom and three oxygen atoms. It is a highly reactive compound and is typically encountered as a colorless to white crystalline solid. SO3 is used in various industrial processes, such as the production of sulfuric acid.

3. H2SO4 (Sulfuric Acid): Sulfuric acid is a strong and highly corrosive acid. Its chemical formula is H2SO4. It is one of the most important industrial chemicals and is widely used in various industrial processes, including the production of fertilizers, chemicals, and batteries. Sulfuric acid is also commonly used in laboratories.

4. BaSO4 (Barium Sulfate): Barium sulfate is a compound composed of one barium atom and one sulfate ion. It is a white crystalline solid that is insoluble in water. Barium sulfate is used in medical imaging procedures (such as barium swallow tests) to enhance X-ray images of the digestive system. It is also used as a contrast medium in some types of medical scans.

These compounds are all related to sulfur chemistry and have various industrial, environmental, and scientific applications.
