Question

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

Answer 1

Ответ:Fe + 2HCl = FeCl2 + H2

FeCl2 + 2NaOH = Fe(OH)2+2NaCl

Fe(OH)2 + H2SO4 = FeSO4 + 2H2O

FeSO4 + 2Al = 3Fe + Al2(SO4)3

Объяснение:

Answer 2

Fe + 2HCl = FeCl2 + H2

FeCl2 + 2H2O = Fe ( OH ) 2 + 2HCl

Fe ( OH ) 2 + H2SO4 = FeSO4 + 2H2O

FeSO4 - Fe + SO4

Answer 3

The sequence you've provided seems to represent a series of chemical reactions involving iron and various compounds. Here's a breakdown of the reactions:

1. Fe (Iron) reacts with FeCl2 (Iron(II) chloride):

   • Fe + FeCl2 → This reaction can potentially form an alloy of iron and iron(II) chloride, although it's not a common reaction.

2. Fe (Iron) reacts with Fe(OH)2 (Iron(II) hydroxide):

   • Fe + Fe(OH)2 → This reaction can potentially form an alloy of iron and iron(II) hydroxide.

3. Fe(OH)2 (Iron(II) hydroxide) reacts with FeSO4 (Iron(II) sulfate):

   • Fe(OH)2 + FeSO4 → This is likely a precipitation reaction, where iron(II) hydroxide reacts with iron(II) sulfate to form a precipitate.

4. The end result is Fe, which means that after the series of reactions, you're left with iron as the product.

Please note that these reactions are simplified, and the actual chemical reactions can be more complex depending on reaction conditions, concentrations, and other factors. If you have a specific question about these reactions or need more detailed information, please provide additional context.
