Oxygen production from potassium chlorate text expression and chemical formula:

Oxygen production from potassium chlorate chemical formula: 2KClO3=(MnO2 △)=2KCl+3O2↑.

Potassium chlorate=== (manganese dioxide above the equals sign, ? below) potassium chloride + oxygen.

This reaction is a decomposition reaction in which one substance produces two or more other substances, in which the element oxygen becomes oxygen monomer and the valency changes.

Potassium chlorate is an inorganic compound with the chemical formula KClO3. It is a colorless or white crystalline powder with a salty and cool taste and a strong oxidizing agent. It is stable at room temperature, but above 400℃, it decomposes and releases oxygen, and can form explosive mixtures with reducing agents, organic materials, flammable materials such as sulfur, phosphorus, or metal powders.

Potassium Chlorate Uses:

Potassium Chlorate has a wide range of uses, used in explosives, fireworks, firecrackers, high-level safety matches, medicine, photographic agents, analytical reagents, oxidizers and rockets, missiles and other propellants. In the same series of propellants, propellants containing potassium chlorate burn faster than propellants containing ammonium chlorate, the minimum pressure at which combustion can take place is higher, and the burning speed index is very high.

Potassium chlorate can produce potassium chloride and oxygen under heated conditions with manganese dioxide as a catalyst, chemistry laboratories do not commonly use the method of heating potassium chlorate to make oxygen (oxygen is impure and dangerous).
