Ozone gas is a form of elemental oxygen containing molecules with three oxygen atoms, O3. Ozone is produced from atmospheric oxygen gas O2, by the high energy outbursts found in lightening storms. Write the unbalanced equation for the formation of ozone gas from oxygen gas. (Include states-of-matter under SATP conditions in your answer.)
