How is good (stratospheric) ozone formed? a. combining an oxygen molecule (o2) an atom of chlorine (cl) b. combining a single oxygen atom (o) with an oxygen molecule (o2) c. combining two single oxygen atoms d. breaking apart an oxygen molecule

The correct answer is option (b). combining a single oxygen atom (O) with an oxygen molecule ().

The molecular formula of the ozone is . the combination of the molecular oxygen with the oxygen atom can result in the formation of the ozone molecule.

As the ozone do not have chlorine in its structure, combining oxygen and chlorine cannot form ozone.

Combining two oxygen atom would form an oxygen molecule, not the ozone.

Breaking oxygen molecule would result in formation oxygen atom, not ozone.

Hence, the options (a), (c), and (d) are incorrect.

what statement best describes the difference between the sympathetic and parasympathetic nervous systems?

the sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. the parasympathetic nervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.

a metamorphic rock would be formed.
