Question

Fe- FeO- FeCl2- Fe(OH)2- Fe(NO3)2

Answer 1

Ответ:

Объяснение:

2Fe + O2 = 2FeO

FeO + 2HCl = FeCl2 + H2O

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

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

Answer 2

The substances you mentioned are chemical compounds containing iron (Fe) in different oxidation states. Let's look at each of them:

1. Fe: This represents elemental iron, which is a metal in its pure form.

2. FeO: This is iron(II) oxide or ferrous oxide, where iron is in the +2 oxidation state. It is a black solid and commonly known as wüstite.

3. FeCl2: This is iron(II) chloride or ferrous chloride, where iron is in the +2 oxidation state. It is a greenish-white crystalline solid.

4. Fe(OH)2: This is iron(II) hydroxide or ferrous hydroxide, where iron is in the +2 oxidation state. It is a light green solid and can be formed when iron reacts with water.

5. Fe(NO3)2: This is iron(II) nitrate or ferrous nitrate, where iron is in the +2 oxidation state. It is a blue-green crystalline solid and can be produced by the reaction of iron with nitric acid.

These compounds represent different forms of iron with varying oxidation states and can have various chemical and physical properties. The oxidation state of iron determines its reactivity and the types of reactions it can undergo.
