Answer 2

Transformation Steps:

The given transformations involve the conversion of iron (Fe) through various chemical reactions. Let's break down each step:

1. Fe → FeCl2: - This transformation involves the reaction between iron (Fe) and chlorine (Cl2) to form iron(II) chloride (FeCl2). - The balanced equation for this reaction is: Fe + Cl2 → FeCl2.

2. FeCl2 → Fe(OH)2: - This transformation involves the reaction between iron(II) chloride (FeCl2) and water (H2O) to form iron(II) hydroxide (Fe(OH)2). - The balanced equation for this reaction is: FeCl2 + 2H2O → Fe(OH)2 + 2HCl [[2]](https://invat.blob.core.windows.net/manuals/9%20%D0%BA%D0%BB%D0%B0%D1%81%D1%81-ru-%D0%A5%D0%B8%D0%BC%D0%B8%D1%8F-2016-.pdf).

3. Fe(OH)2 → FeO + Fe: - This transformation involves the decomposition of iron(II) hydroxide (Fe(OH)2) into iron(II) oxide (FeO) and elemental iron (Fe). - The balanced equation for this reaction is: 2Fe(OH)2 → FeO + Fe + 2H2O [[6]](https://chemege.ru/iron/).

4. Fe → FeCl3: - This transformation involves the reaction between iron (Fe) and chlorine (Cl2) to form iron(III) chloride (FeCl3). - The balanced equation for this reaction is: 2Fe + 3Cl2 → 2FeCl3.

5. FeCl3 → Fe(OH)3: - This transformation involves the reaction between iron(III) chloride (FeCl3) and water (H2O) to form iron(III) hydroxide (Fe(OH)3). - The balanced equation for this reaction is: FeCl3 + 3H2O → Fe(OH)3 + 3HCl [[2]](https://invat.blob.core.windows.net/manuals/9%20%D0%BA%D0%BB%D0%B0%D1%81%D1%81-ru-%D0%A5%D0%B8%D0%BC%D0%B8%D1%8F-2016-.pdf).

6. Fe(OH)3 → Fe2O3: - This transformation involves the dehydration of iron(III) hydroxide (Fe(OH)3) to form iron(III) oxide (Fe2O3). - The balanced equation for this reaction is: 2Fe(OH)3 → Fe2O3 + 3H2O [[6]](https://chemege.ru/iron/).

Summary:

The series of transformations can be summarized as follows:

Fe → FeCl2 → Fe(OH)2 → FeO + Fe → FeCl3 → Fe(OH)3 → Fe2O3

These transformations involve various chemical reactions that result in the conversion of iron (Fe) into different compounds, including iron(II) chloride, iron(II) hydroxide, iron(II) oxide, iron(III) chloride, iron(III) hydroxide, and iron(III) oxide.
