Answer 2

The sequence you provided represents a common chemical transformation pathway of iron (Fe) compounds. Let's break it down step by step:

1. Fe (Iron): The starting point of the sequence is elemental iron (Fe), which is a metal.

2. Fe2O3 (Iron(III) oxide): Fe reacts with oxygen (O2) in the presence of air or water to form iron(III) oxide, commonly known as rust. The chemical formula of iron(III) oxide is Fe2O3.

3. Fe(OH)3 (Iron(III) hydroxide): When iron(III) oxide (Fe2O3) comes into contact with water (H2O), it can react to form iron(III) hydroxide, which has the chemical formula Fe(OH)3.

4. Fe2(SO4)3 (Iron(III) sulfate): Iron(III) hydroxide (Fe(OH)3) can undergo a reaction with sulfuric acid (H2SO4) to form iron(III) sulfate. The chemical formula of iron(III) sulfate is Fe2(SO4)3.

In summary, the sequence represents the transformation of iron (Fe) into iron(III) sulfate (Fe2(SO4)3) through intermediate stages of iron(III) oxide (Fe2O3) and iron(III) hydroxide (Fe(OH)3). Each step in this sequence represents a different chemical reaction that occurs under specific conditions.
