When Potassium Chlorate is Heated in the Presence of Manganese Dioxide Catalyst, it Decomposes to form Potassium Chloride and Oxygen Gas. Represent this in the Form of a Balanced Chemical Equation

Answer: When potassium chlorate (KClO₃) is heated in the presence of a manganese dioxide catalyst, it decomposes into potassium chloride and oxygen gas.

The balanced chemical equation looks like this:

KClO₃   2KCl  +  3O₂

Decomposition reaction is defined as  the chemical process in which a chemical substance breaks down into two or more chemical compounds when heated. It’s thought to be the polar opposite of a combination reaction.
