Question

Fe2O3-Fe-FeCl2-FeSO4-Fe(OH)2-FeO-FeSO4

Answer 1

Fe2O3+6H2=2Fe+3H2O
Fe+2HCl=FeCl2+H2
FeCl2+H2SO4=FeSO4+ 2HCl
FeSO4+2NaOH=Fe(OH)2+Na2SO4
Fe(OH)2=FeO+H2O
FeO+SO3=FeSO4

Answer 2

The series you've mentioned represents a sequence of chemical reactions involving iron (Fe) and various compounds. Let's go through each compound and its corresponding reactions:

1. Fe2O3 (Iron(III) oxide): Iron(III) oxide is a compound composed of two iron atoms bonded to three oxygen atoms. It is commonly known as rust. If Fe2O3 is subjected to a reducing agent or high temperatures, it can be converted to elemental iron (Fe).

2. Fe (Elemental iron): Elemental iron refers to pure iron in its metallic form. This can be obtained by reducing iron(III) oxide (Fe2O3) through a reaction known as the reduction of iron.

3. FeCl2 (Iron(II) chloride): Iron(II) chloride is a compound consisting of one iron atom bonded to two chlorine atoms. It can be obtained by reacting elemental iron (Fe) with hydrochloric acid (HCl).

4. FeSO4 (Iron(II) sulfate): Iron(II) sulfate is a compound containing one iron atom bonded to one sulfate ion (SO4^2-). It can be produced by reacting elemental iron (Fe) with sulfuric acid (H2SO4).

5. Fe(OH)2 (Iron(II) hydroxide): Iron(II) hydroxide is a compound composed of one iron atom bonded to two hydroxide ions (OH-). It can be formed by reacting iron(II) sulfate (FeSO4) with a base, such as sodium hydroxide (NaOH).

6. FeO (Iron(II) oxide): Iron(II) oxide is a compound consisting of one iron atom bonded to one oxygen atom. It can be obtained by the thermal decomposition of iron(II) hydroxide (Fe(OH)2).

7. FeSO4 (Iron(II) sulfate): Iron(II) sulfate is the same compound mentioned earlier. It can be formed by dissolving elemental iron (Fe) in sulfuric acid (H2SO4).

Please note that the reactions and conditions mentioned here are general and may vary depending on the specific experimental conditions and reactants used.
