Which of the following is an ozone depleting substance ods

Q: Is an ozone

The ozone layer is part of the earths upper atmosphere and protects all life from ultra-violet radiation. The Montreal Protocol was signed in 1987 to control and phase out chemicals which damage the ozone layer, referred to as Ozone Depleting Substances (ODS”).

Uh-Oh! That’s all you get for now.

Is an ozone

The ozone layer is part of the earth's upper atmosphere and protects all life from ultra-violet radiation. The Montreal Protocol was signed in 1987 to control and phase out chemicals which damage the ozone layer, referred to as Ozone Depleting Substances (“ODS”).

Which are ozone

Ozone depleting substances.

chlorofluorocarbons (CFCs).

halon..

carbon tetrachloride (CCl4).

methyl chloroform (CH3CCl3).

hydrobromofluorocarbons (HBFCs).

hydrochlorofluorocarbons (HCFCs).

methyl bromide (CH3Br).

bromochloromethane (CH2BrCl).

Which of the following are ozone

The correct answer is Chlorofluorocarbons. Chlorofluorocarbons(CFC) are responsible for ozone layer depletion. Ozone gas is continuously formed by the action of UV rays on molecular oxygen and also degraded into molecular oxygen in the stratosphere.
