Question

Fe→FeCI3→Fe(OH)3→Fe2O3→Fe(NO3)3 ↓ FeCI2 →Fe(OH)2 →FeSO4 →FeCI2

Answer 1

Ответ:

1.Fe+Cl=FeCl3

2.2FeCl3+3Ca(OH)2=2Fe(OH)3+3CaCl2

3.4Fe(OH)3=2Fe2O3+6H2O

4.Fe2O3+3HNO3=Fe(NO3)3+3H2O

1.Fe+Cl=FeCl2(так как,Fe может быть 2-х валентным и 3-х валентным)

2.FeCl2+Cu(OH)2=Fe(OH)2+CuCl2

3.Fe(OH)2+CaSO4=FeSO4+Ca(OH)2

4.FeSO4+2HCl=FeCl2+H2SO4

Answer 2

The sequence of reactions you provided involves the transformation of iron (Fe) through various chemical compounds. Let's go through each step:

1. Fe → FeCl3: Iron (Fe) reacts with chlorine (Cl2) to form iron(III) chloride (FeCl3).

2. FeCl3 → Fe(OH)3: Iron(III) chloride (FeCl3) reacts with water (H2O) to produce iron(III) hydroxide (Fe(OH)3).

3. Fe(OH)3 → Fe2O3: Iron(III) hydroxide (Fe(OH)3) undergoes dehydration to form iron(III) oxide (Fe2O3).

4. Fe2O3 → Fe(NO3)3: Iron(III) oxide (Fe2O3) reacts with nitric acid (HNO3) to produce iron(III) nitrate (Fe(NO3)3).

5. FeCl2 → Fe(OH)2: Iron(II) chloride (FeCl2) reacts with water (H2O) to form iron(II) hydroxide (Fe(OH)2).

6. Fe(OH)2 → FeSO4: Iron(II) hydroxide (Fe(OH)2) undergoes oxidation by reacting with sulfuric acid (H2SO4) to produce iron(II) sulfate (FeSO4).

7. FeSO4 → FeCl2: Iron(II) sulfate (FeSO4) reacts with hydrochloric acid (HCl) to yield iron(II) chloride (FeCl2).

It's important to note that some of these reactions may require specific reaction conditions such as temperature, pH, or catalysts to proceed effectively. Also, the presence of excess reagents or impurities may influence the reaction outcomes.
