Write down the equation of reactions: iron → iron (2) chloride → iron (3) chloride → iron (3) hydroxide

Write down the equation of reactions: iron → iron (2) chloride → iron (3) chloride → iron (3) hydroxide → iron (3) oxide → iron.

We compose the reaction equations:
Fe + 2HCl = FeCl2 + H2 – redox reaction (ORR);
2FeCl2 + Cl2 = 2FeCl3 – OBP;
FeCl3 + 3NaOH = Fe (OH) 3 + 3NaCl – ion exchange reaction;
2Fe (OH) 3 = Fe2O3 + 3H2O – decomposition reaction;
Fe2O3 + 2Al = 2Fe + Al2O3 – aluminothermy is carried out at a high temperature, it is used in metallurgy to obtain metals;
The reactions carried out show a genetic relationship between a simple substance, a metal, salts, hydroxides, oxides.
