When solid potassium chlorate is heated, it decomposes to form solid potassium chloride and oxygen gas. express your answer as a balanced chemical equation. identify all of the phases in your answer?

When the solid potassium chlorate is heated, it decomposes to form solid potassium chloride and oxygen gas so the balance chemical equation is below.

Decomposition of potassium chlorate by heating:
The balance chemical equation is 2KClO3(s) + heat = 2KCl(s) + 3O2↑(g)
