CaClO₃ → CaCl₂ + O₂

Here's how to balance it:

1. Count atoms on each side:

* Left side (Reactants): 1 Ca, 1 Cl, 3 O

* Right side (Products): 1 Ca, 2 Cl, 2 O

2. Balance Chlorine (Cl):

* There are 2 Cl on the right side and 1 on the left. Put a coefficient of 2 in front of CaClO₃.

* 2 CaClO₃ → CaCl₂ + O₂

3. Balance Calcium (Ca):

* Now we have 2 Ca on the left, but only 1 on the right. Add a coefficient of 2 in front of CaCl₂.

* 2 CaClO₃ → 2 CaCl₂ + O₂

4. Balance Oxygen (O):

* We have 6 O on the left (2 * 3) and 2 O on the right. Put a coefficient of 3 in front of O₂.

* 2 CaClO₃ → 2 CaCl₂ + 3 O₂

The balanced equation is:

2 CaClO₃ → 2 CaCl₂ + 3 O₂
