Question

FeO=Fe=FeSO4=Fe(OH)2=Fe(NO3)2​

Answer 1

Ответ:

Объяснение:

FeO + Zn = Fe + ZnO↓

Fe + H2SO4 = FeSO4 + H2↑

FeSO4 + 2NaOH = Fe(OH)2↓ + Na2SO4

Fe(OH)2 + 2HNO3 = Fe(NO3)2 + 2H2O

Answer 2

Ответ:

FeO+H2-->Fe+H2O

Fe+H2SO4-->FeSO4+H2

FeSO4+2NaOH-->Fe(OH)2+Na2SO4

Fe(OH)2+2HNO3-->Fe(NO3)2+2H2O

Answer 3

It looks like you've listed a series of chemical compounds involving iron (Fe) and various ligands. Each compound represents a different chemical species of iron with different oxidation states and coordination environments. Let's break down each of these compounds:

1. FeO (Iron(II) Oxide):

   • This is also known as ferrous oxide or iron monoxide.
   • It's a compound where iron has a +2 oxidation state.
   • The chemical formula indicates that there is one iron atom bonded to one oxygen atom.

2. Fe (Elemental Iron):

   • This refers to pure iron in its metallic form.
   • Elemental iron has a neutral charge and consists solely of iron atoms.

3. FeSO4 (Iron(II) Sulfate):

   • This compound is also known as ferrous sulfate.
   • It contains iron in the +2 oxidation state and sulfate ions (SO4^2-) as ligands.
   • The chemical formula indicates that there is one iron atom bonded to one sulfate ion.

4. Fe(OH)2 (Iron(II) Hydroxide):

   • This compound is ferrous hydroxide.
   • It consists of iron in the +2 oxidation state and hydroxide ions (OH-) as ligands.
   • The chemical formula suggests that there is one iron atom bonded to two hydroxide ions.

5. Fe(NO3)2 (Iron(II) Nitrate):

   • This compound is ferrous nitrate.
   • It contains iron in the +2 oxidation state and nitrate ions (NO3-) as ligands.
   • The chemical formula indicates that there is one iron atom bonded to two nitrate ions.

It's important to note that the oxidation state of iron in each compound is different. This results in different chemical properties and reactivity for each compound. Additionally, the ligands (oxygen, sulfate, hydroxide, and nitrate) play a significant role in determining the overall structure and properties of these compounds.
