Given the task, it is necessary to write down the equation of chemical reactions for the following chain of compounds.

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

1. Substitution reaction.

Fe + 2HCl = FeCl2 + H2.
The result is ferric chloride and hydrogen.

2. Reaction of exchange.
FeCl2 + 2NaOH = Fe (OH) 2 + 2NaCl.
As a result, iron hydroxide and sodium chloride are formed.

3. Reaction of exchange.
Fe (OH) 2 + H2SO4 = FeSO4 + 2H2O.
the result is ferrous sulfate and water.

4. Reaction of exchange.
FeSO4 + 2NaOH = Fe (OH) 2 + Na2SO4.
As a result, iron hydroxide and sodium sulfate are formed.

5. Decomposition reaction.
Fe (OH) 2 → H2O + FeO.
The result is water and iron oxide.

6. Substitution reaction.
FeO + CO → Fe + CO2 ↑.
The result is iron and carbon monoxide.
