Answer 2

The chemical reactions you've provided involve the transformation of iron (Fe) into various compounds. Let's break down these reactions step by step:

1. Fe → FeSO4:

   • In this step, metallic iron (Fe) reacts with sulfuric acid (H2SO4) to produce iron(II) sulfate (FeSO4) and hydrogen gas (H2). The balanced chemical equation for this reaction is:

     Fe + H2SO4 → FeSO4 + H2
     

2. FeSO4 → Fe(OH)2:

   • In this step, iron(II) sulfate (FeSO4) reacts with a base (such as sodium hydroxide, NaOH) to form iron(II) hydroxide (Fe(OH)2) and sodium sulfate (Na2SO4). The balanced chemical equation for this reaction is:

     FeSO4 + 2NaOH → Fe(OH)2 + Na2SO4
     

So, in summary, iron (Fe) reacts with sulfuric acid (H2SO4) to form iron(II) sulfate (FeSO4) and hydrogen gas (H2). Then, iron(II) sulfate reacts with a base (e.g., sodium hydroxide) to form iron(II) hydroxide (Fe(OH)2) and sodium sulfate (Na2SO4). These reactions involve the transformation of iron from its metallic form to iron(II) sulfate and then to iron(II) hydroxide.
