Answer 2

The sequence you've mentioned appears to describe a series of chemical reactions involving iron (Fe) and sulfur (S) compounds. Let's break it down step by step:

1. Fe → FeO: This represents the oxidation of iron (Fe) to form iron oxide (FeO). The reaction can be written as:

   4 Fe + 3 O₂ → 2 Fe₂O₃

   Iron (Fe) reacts with oxygen (O₂) to form iron(III) oxide (Fe₂O₃), commonly known as rust.

2. FeO → Fe₂(SO₄)₃: This represents the further oxidation of iron oxide (FeO) to form iron(III) sulfate (Fe₂(SO₄)₃). The reaction can be written as a two-step process:

   a. First, you need to convert FeO to Fe₂O₃ (iron(III) oxide):

   2 FeO + 1.5 O₂ → Fe₂O₃

   b. Then, you react iron(III) oxide (Fe₂O₃) with sulfuric acid (H₂SO₄) to form iron(III) sulfate (Fe₂(SO₄)₃):

   Fe₂O₃ + 3 H₂SO₄ → Fe₂(SO₄)₃ + 3 H₂O

So, the overall sequence is the oxidation of iron (Fe) to form iron(III) oxide (Fe₂O₃), followed by the reaction of iron(III) oxide with sulfuric acid (H₂SO₄) to form iron(III) sulfate (Fe₂(SO₄)₃). These reactions represent common chemical processes, especially in the context of rust formation and metal corrosion.
