Which two chemicals, acted upon by sunlight, form ozone in the atmosphere? volatile organic compounds and sulfur dioxide volatile organic compounds and nitrogen dioxide chlorofluorocarbons and sulfur dioxide chlorofluorocarbons and nitrogen dioxide

The two chemicals are; volatile organic compounds and nitrogen dioxide.

Explanation:

Ozone is a naturally occurring inorganic molecule in the stratosphere when sunlight causes the splitting of an oxygen which reacts with another free oxygen molecule (), forming ozone (). Most volatile organic compounds and nitrogen dioxide emitted to the atmosphere are acted upon by sunlight to yield ozone, .

The ozone layer has a high concentration of ozone, reduces the amount of incident radiation from the Sun (ultraviolet radiation) to the earth. But it is being depleted by human activities on the earth.
