Answer 2

Transformation: Fe -> FeCl2 -> Fe(OH)2 -> Fe(OH)3 -> FeCl3

The transformation you provided involves a series of chemical reactions starting with iron (Fe) and ending with iron(III) chloride (FeCl3). Let's break down each step of the transformation:

1. Fe -> FeCl2: - In this step, iron (Fe) reacts with chlorine (Cl2) to form iron(II) chloride (FeCl2). - The balanced chemical equation for this reaction is: Fe + Cl2 -> FeCl2. - Iron(II) chloride is a greenish solid compound.

2. FeCl2 -> Fe(OH)2: - In this step, iron(II) chloride (FeCl2) reacts with a base, such as sodium hydroxide (NaOH), to form iron(II) hydroxide (Fe(OH)2). - The balanced chemical equation for this reaction is: FeCl2 + 2NaOH -> Fe(OH)2 + 2NaCl. - Iron(II) hydroxide is a greenish precipitate.

3. Fe(OH)2 -> Fe(OH)3: - In this step, iron(II) hydroxide (Fe(OH)2) undergoes oxidation to form iron(III) hydroxide (Fe(OH)3). - The balanced chemical equation for this reaction is: 2Fe(OH)2 + H2O + 1/2O2 -> 2Fe(OH)3. - Iron(III) hydroxide is a reddish-brown precipitate.

4. Fe(OH)3 -> FeCl3: - In this final step, iron(III) hydroxide (Fe(OH)3) reacts with hydrochloric acid (HCl) to form iron(III) chloride (FeCl3). - The balanced chemical equation for this reaction is: Fe(OH)3 + 3HCl -> FeCl3 + 3H2O. - Iron(III) chloride is a yellowish-brown solid compound.

Please note that the reactions mentioned above are simplified representations of the transformations. The actual reaction conditions, stoichiometry, and specific reagents used may vary depending on the experimental setup.
