2)2H2S+3O2=2SO2+2H2O

3)2SO2+O2=2SO3

4)SO3+H2O=H2SO4

5)H2SO4+Ba=BaSO4 + H2

6)BaSO4+Cu=CuSO4+Ba

Answer 2

Chemical Reaction Equations for the Given Transformations

To achieve the transformations mentioned, the following chemical reactions can be used:

1. Sulfur to Hydrogen Sulfide (H2S): - The reaction equation for the transformation of sulfur to hydrogen sulfide is: ``` S + 2H2 → 2H2S ```

2. Hydrogen Sulfide (H2S) to Sulfur Dioxide (SO2): - The reaction equation for the transformation of hydrogen sulfide to sulfur dioxide is: ``` 2H2S + 3O2 → 2SO2 + 2H2O ```

3. Sulfur Dioxide (SO2) to Sulfur Trioxide (SO3): - The reaction equation for the transformation of sulfur dioxide to sulfur trioxide is: ``` 2SO2 + O2 → 2SO3 ```

4. Sulfur Trioxide (SO3) to Sulfuric Acid (H2SO4): - The reaction equation for the transformation of sulfur trioxide to sulfuric acid is: ``` SO3 + H2O → H2SO4 ```

5. Sulfuric Acid (H2SO4) to Barium Sulfate (BaSO4) and Copper(II) Sulfate (CuSO4): - The reaction equations for the transformation of sulfuric acid to barium sulfate and copper(II) sulfate are: ``` H2SO4 + BaCl2 → BaSO4 + 2HCl H2SO4 + CuO → CuSO4 + H2O ```

The type of reactions involved in these transformations includes combination reactions, combustion reactions, and precipitation reactions
