Answer 2

Chemical Formula for Substance X in the Transformation Scheme Fe > FeCl2 > Fe(OH)3 > X

The chemical formula for substance X in the given transformation scheme is Fe2O3 (Option A).

The transformation scheme starts with iron (Fe), which reacts with chlorine (Cl2) to form iron(II) chloride (FeCl2). Then, iron(II) chloride reacts with water (H2O) to form iron(III) hydroxide (Fe(OH)3). Finally, iron(III) hydroxide undergoes a further transformation to form substance X.

Based on the given options, the chemical formula that matches substance X is Fe2O3.
