Answer 2

The series of chemical reactions you provided involve the transformation of various elements and compounds. Here's a breakdown of each reaction:

1. Fe → FeSO4: Iron (Fe) reacts with sulfuric acid (H2SO4) to form ferrous sulfate (FeSO4).

2. FeSO4 → Fe(OH)2: Ferrous sulfate (FeSO4) reacts with a base, such as sodium hydroxide (NaOH), to form ferrous hydroxide (Fe(OH)2).

3. Fe(OH)2 → Fe(OH)3: Ferrous hydroxide (Fe(OH)2) undergoes oxidation to form ferric hydroxide (Fe(OH)3).

4. Fe(OH)3 → Fe2O3: Ferric hydroxide (Fe(OH)3) loses water to form iron(III) oxide (Fe2O3), also known as rust.

5. Fe2O3 → FeCl3: Iron(III) oxide (Fe2O3) reacts with hydrochloric acid (HCl) to form ferric chloride (FeCl3).

6. FeCl3 → Fe: Ferric chloride (FeCl3) can be reduced to elemental iron (Fe) using a reducing agent like hydrogen gas (H2).

7. Al → Al2O3: Aluminum (Al) reacts with oxygen (O2) to form aluminum oxide (Al2O3), commonly known as alumina.

8. Al2O3 → AlCl3: Aluminum oxide (Al2O3) reacts with hydrochloric acid (HCl) to form aluminum chloride (AlCl3).

9. AlCl3 → Al(OH)3: Aluminum chloride (AlCl3) reacts with a base, such as sodium hydroxide (NaOH), to form aluminum hydroxide (Al(OH)3).

10. Al(OH)3 → Al2O3·H2O: Aluminum hydroxide (Al(OH)3) dehydrates to form hydrated aluminum oxide (Al2O3·H2O).

11. Al2O3·H2O → SO2: Hydrated aluminum oxide (Al2O3·H2O) decomposes when heated to produce sulfur dioxide (SO2).

12. SO2 → SO3: Sulfur dioxide (SO2) reacts with oxygen (O2) in the presence of a catalyst to form sulfur trioxide (SO3).

13. SO3 → H2SO4: Sulfur trioxide (SO3) reacts with water (H2O) to form sulfuric acid (H2SO4).

14. H2SO4 → KHSO4: Sulfuric acid (H2SO4) reacts with potassium hydroxide (KOH) to form potassium hydrogen sulfate (KHSO4).

15. KHSO4 → K2SO4: Potassium hydrogen sulfate (KHSO4) can lose a hydrogen ion to form potassium sulfate (K2SO4).

16. K2SO4 → BaSO4: Potassium sulfate (K2SO4) can react with barium chloride (BaCl2) to form barium sulfate (BaSO4).

17. Cu → CuO: Copper (Cu) reacts with oxygen (O2) to form copper(II) oxide (CuO).

18. CuO → Cu(NO3)2: Copper(II) oxide (CuO) reacts with nitric acid (HNO3) to form copper(II) nitrate (Cu(NO3)2).

19. Cu(NO3)2 → Cu(OH)2: Copper
