Chemical Reactions in the Given Chain

The given chain of chemical reactions involves the transformation of Fe(NO3)3 to Fe(OH)3, then to Fe2O3, Fe, FeCl, Fe, FeSO4, and finally to Fe(OH)2. Let's break down each step of the chain:

1. Fe(NO3)3 to Fe(OH)3: - Fe(NO3)3 is iron(III) nitrate, which can react with a base to form iron(III) hydroxide (Fe(OH)3).

2. Fe(OH)3 to Fe2O3: - Iron(III) hydroxide (Fe(OH)3) can undergo a dehydration reaction to form iron(III) oxide (Fe2O3).

3. Fe2O3 to Fe: - Iron(III) oxide (Fe2O3) can be reduced to elemental iron (Fe) by a suitable reducing agent.

4. Fe to FeCl: - The reaction of elemental iron (Fe) with chlorine gas (Cl2) can form iron(III) chloride (FeCl3).

5. FeCl to Fe: - Iron(III) chloride (FeCl3) can be reduced to elemental iron (Fe) by a suitable reducing agent.

6. Fe to FeSO4: - Elemental iron (Fe) can react with sulfuric acid (H2SO4) to form iron(II) sulfate (FeSO4).

7. FeSO4 to Fe(OH)2: - Iron(II) sulfate (FeSO4) can react with a base to form iron(II) hydroxide (Fe(OH)2).

Conclusion

In summary, the given chain of reactions involves the transformation of Fe(NO3)3 to Fe(OH)3, then to Fe2O3, Fe, FeCl, Fe, FeSO4, and finally to Fe(OH)2. Each step of the chain represents a specific chemical reaction, as described above.
