1) 2Fe + 3Cl2 → 2FeCl3 (iron (III) chloride; compound reaction).

2) FeCl3 + 3NaOH → Fe (OH) 3 + 3NaCl (iron (III) hydroxide, sodium chloride; exchange reaction, the reaction proceeds, since a precipitate is formed in the form of iron (III) hydroxide).

3) 2Fe (OH) 3 → Fe2O3 + 3H2O (conditions: temperature; iron (III) oxide; decomposition reaction).

4) Fe2O3 + 3H2 → 2Fe + 3H2O (iron; substitution reaction).

5) Fe + 2HCl → FeCl2 + H2 (iron (II) chloride, hydrogen; substitution reaction).

6) FeCl2 + 2NaOH → Fe (OH) 2 + 2NaCl (iron (II) hydroxide, sodium chloride; exchange reaction, the reaction proceeds, since a precipitate is formed in the form of iron (II) hydroxide).
