The decomposition of potassium chlorate (KClO₃) produces potassium chloride (KCl) and oxygen gas (O₂). Here's the balanced chemical equation:

2KClO₃ → 2KCl + 3O₂

Explanation:

* Reactant: Potassium chlorate (KClO₃)

* Products: Potassium chloride (KCl) and oxygen gas (O₂)

* Balancing: The equation is balanced to ensure that the number of atoms of each element is the same on both sides of the equation.

Important Notes:

* This reaction requires heat to initiate the decomposition.

* The reaction is often catalyzed by the presence of manganese dioxide (MnO₂).

* This reaction is a common method for producing oxygen gas in the laboratory.
