Write down the reaction equations of possible methods for obtaining ferric chloride (2) by the reactions

Write down the reaction equations of possible methods for obtaining ferric chloride (2) by the reactions of compound, substitution, exchange.

On assignment, we need to get the ferric chloride salt in three different ways, in three different reactions: the reaction of compound, substitution and exchange.

First, consider the reaction of combining two elements, chlorine and iron. This reaction takes place under the influence of temperature. We write it as follows:
Fe + Cl₂ = FeCl₂

The substitution reaction, in order to obtain ferric chloride, takes place between the iron and hydrochloric acid. Also, hydrogen is released in this reaction. Graphically, this equation of a chemical reaction can be expressed as follows:

Fe + 2 HCl = FeCl₂ + H₂ ↑

And last, consider the exchange reaction between iron hydroxide and hydrochloric acid. We get the desired salt, ferric chloride and water. The molecular equation of the reaction can be written as follows:

Fe (OH) ₂ + 2 HCl = FeCl₂ + 2 H₂O.
