When oxygen, O₂, is passed through an electrical spark (lightning is a good natural source of an electrical spark), ozone, O₃, is formed. When the equation is balanced, the coefficient of ozone is

Question

Quizplus · Accepted Answer

The balanced chemical equation for the formation of ozone from oxygen is 3O2 → 2O3. This shows that for every three molecules of oxygen (O2), two molecules of ozone (O3) are formed, making the coefficient of ozone 2.
