Make up the reaction equations with which you can carry out the following transformations: KCl-Cl2-KClO3-KCl-K-KOH.

1. Electrolysis of a concentrated solution of potassium chlorine:
2KCl + 2H2O = 2KOH + Cl2 + H2.
2. The reaction of disproportionation of hypochlorite, which is formed by the interaction of chlorine with alkali:
2KOH + Cl2 = KClO + KCl + H2O.
3KClO = KClO3 + 2KCl.
3. Decomposition of potassium chlorate at 150-300 ° C in the presence of a MnO2 catalyst:
2KClO3 = 2KCl + 3O2.
4. Electrolysis in the melt:
2KCl = 2K + Cl2.
5. Hydration reaction:
2K + 2H2O = 2KOH + H2.
