Answer 3

The given sequence represents a series of chemical reactions involving iron (Fe) and various compounds. Let's break down each step:

1. Fe → FeCl2: - This reaction involves the reaction of iron (Fe) with hydrochloric acid (HCl) to form iron(II) chloride (FeCl2) and hydrogen gas (H2). - The balanced equation for this reaction is: Fe + 2HCl → FeCl2 + H2.

2. FeCl2 → Fe(OH)2: - This reaction involves the reaction of iron(II) chloride (FeCl2) with a base, such as sodium hydroxide (NaOH), to form iron(II) hydroxide (Fe(OH)2). - The balanced equation for this reaction is: FeCl2 + 2NaOH → Fe(OH)2 + 2NaCl.

3. Fe(OH)2 → FeO: - This reaction involves the dehydration of iron(II) hydroxide (Fe(OH)2) to form iron(II) oxide (FeO). - The balanced equation for this reaction is: Fe(OH)2 → FeO + H2O.

4. FeO → Fe(NO3)2: - This reaction involves the reaction of iron(II) oxide (FeO) with nitric acid (HNO3) to form iron(II) nitrate (Fe(NO3)2). - The balanced equation for this reaction is: FeO + 2HNO3 → Fe(NO3)2 + H2O.

Please note that the given sequence of reactions is not complete, and there may be additional reactions or steps missing between the mentioned compounds.
