Question

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?

Answer 1

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)
