Answer 2

b) SO2 -> S -> SO -> SO3- -> H2SO4 -> CuSO4

1. SO2 (sulfur dioxide) - S (sulfur): Sulfur dioxide (SO2) is converted to elemental sulfur (S) through various processes, such as the Claus process or the contact process. The details of the conversion method would depend on the specific conditions and requirements.

2. S (sulfur) - SO (sulfur monoxide): Elemental sulfur (S) can react with oxygen (O2) to form sulfur monoxide (SO). This reaction occurs at high temperatures, typically above 1000 degrees Celsius.

3. SO (sulfur monoxide) - SO3- (sulfur trioxide): Sulfur monoxide (SO) can further react with oxygen (O2) to form sulfur trioxide (SO3). This reaction usually occurs in the presence of a catalyst, such as vanadium pentoxide (V2O5), at elevated temperatures.

4. SO3- (sulfur trioxide) - H2SO4 (sulfuric acid): Sulfur trioxide (SO3) can react with water (H2O) to form sulfuric acid (H2SO4). This reaction is highly exothermic and is typically carried out using a multi-step process, involving the absorption of SO3 in concentrated sulfuric acid.

5. H2SO4 (sulfuric acid) - CuSO4 (copper(II) sulfate): Sulfuric acid (H2SO4) can react with copper(II) oxide (CuO) or copper(II) hydroxide (Cu(OH)2) to produce copper(II) sulfate (CuSO4) and water (H2O). The reaction involves the displacement of hydrogen from sulfuric acid by copper, resulting in the formation of copper(II) sulfate.

Please note that these transformations represent a series of chemical reactions, and the actual processes and conditions involved may vary depending on the specific reaction conditions and desired products.
