Answer

Ca(ClO₃)₂ → CaCl₂ + 3O₂

Procedure

Calcium chlorate decomposes to give oxygen and calcium chloride.

Calcium chlorate has a chemical formula of Ca(ClO3)₂, calcium chloride (CaCl₂), and molecular oxygen (O₂).

The reaction can be written as following

Ca(ClO₃)₂ → CaCl₂ + O₂

The equation is not balanced because the number of atoms of the oxygen element is not the same on both sides of the equation. The equation can be balanced by adding 3 as a coefficient for oxygen as follows:

Ca(ClO₃)₂ → CaCl₂ + 3O₂
