Question

Fe2 O3-->Fe-->Fe Cl2-->Fe So4-->Fe(OH)2-->Fe O

Answer 1

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

Fe2O3 + 3 H2 =  2 Fe + 3 H2O

Fe+2 HCl=FeCl2+H2

FeCl2+H2SO4=FeSO4+2 HCl

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

Fe(OH)2=FeO+H2O

Answer 2

It looks like you've provided a list of chemical reactions involving iron (Fe) and some other substances. However, the reactions seem incomplete, and some of the products might not be accurately represented. I'll do my best to complete the reactions and clarify any inaccuracies:

1. Fe2O3 (Iron(III) oxide) --> Fe + O2 This is a decomposition reaction where Iron(III) oxide breaks down into Iron metal and Oxygen gas.

2. Fe + Cl2 (Chlorine gas) --> FeCl2 (Iron(II) chloride) This is a synthesis reaction where Iron reacts with Chlorine gas to form Iron(II) chloride.

3. FeCl2 (Iron(II) chloride) + H2SO4 (Sulfuric acid) --> FeSO4 (Iron(II) sulfate) + 2 HCl (Hydrochloric acid) This is a double displacement reaction where Iron(II) chloride reacts with Sulfuric acid to produce Iron(II) sulfate and Hydrochloric acid.

4. FeSO4 (Iron(II) sulfate) + 2 NaOH (Sodium hydroxide) --> Fe(OH)2 (Iron(II) hydroxide) + Na2SO4 (Sodium sulfate) This is another double displacement reaction where Iron(II) sulfate reacts with Sodium hydroxide to form Iron(II) hydroxide and Sodium sulfate.

5. 4 Fe(OH)2 (Iron(II) hydroxide) + O2 (Oxygen gas) + 2 H2O (Water) --> 2 Fe2O3 (Iron(III) oxide) + 4 OH- (Hydroxide ions) This is a redox reaction where Iron(II) hydroxide is oxidized by Oxygen gas to form Iron(III) oxide and water, while Oxygen gets reduced.

Overall, the reactions can be summarized as follows:

Fe2O3 (Iron(III) oxide) --> Fe + O2 Fe + Cl2 (Chlorine gas) --> FeCl2 (Iron(II) chloride) FeCl2 (Iron(II) chloride) + H2SO4 (Sulfuric acid) --> FeSO4 (Iron(II) sulfate) + 2 HCl (Hydrochloric acid) FeSO4 (Iron(II) sulfate) + 2 NaOH (Sodium hydroxide) --> Fe(OH)2 (Iron(II) hydroxide) + Na2SO4 (Sodium sulfate) 4 Fe(OH)2 (Iron(II) hydroxide) + O2 (Oxygen gas) + 2 H2O (Water) --> 2 Fe2O3 (Iron(III) oxide) + 4 OH- (Hydroxide ions)
