Which substances contain ozone-depleting substances?
This page provides information on compounds recognized as ozone-depleting substances ( ODS. ODS include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, hydrobromofluorocarbons, chlorobromomethane, and methyl chloroform.
What are ozone-depleting substances give examples?
Ozone depleting substances include:
- chlorofluorocarbons (CFCs)
- hydrochlorofluorocarbons (HCFCs)
- hydrobromoflurocarbons (HBFCs)
- halons.
- methyl bromide.
- carbon tetrachloride.
- methyl chloroform.
What are ozone-depleting substances ODSs )? How they are released to the atmosphere?
Ozone-depleting substances (ODS) are halogen gases containing chlorine and/or bromine which have the potential to break down ozone in the stratosphere. There are a significant number of ODS, including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), methyl chloride and bromide, and halons.
Which products contain ozone-depleting substances Mcq?
Ozone Layer Depletion MCQ Question 11 Detailed Solution The correct answer is CFCs. Chlorofluorocarbons (CFCs) are mainly responsible for ozone layer depletion. Refrigerators, air-conditioners, Fire extinguishers, Adhesives, aerosols are the major sources of ozone-depleting substances.
Which compounds are responsible for the depletion of ozone layer Class 10?
Chlorofluorocarbons or CFCs are the main cause of ozone layer depletion.
Which element in refrigerant depletes the ozone layer?
Molina discovered that chlorofluorocarbons (CFCs) could deplete Earth’s atmospheric ozone layer, which blocks the sun’s damaging ultraviolet rays. When the scientists reported their findings in 1974, CFCs were widely used as refrigerant gases and as propellants in aerosol sprays.
Which element is most responsible for depleting the ozone layer?
As explained above, the primary cause of ozone depletion is the presence of chlorine-containing source gases (primarily CFCs and related halocarbons). In the presence of UV light, these gases dissociate, releasing chlorine atoms, which then go on to catalyze ozone destruction.
Which of the following have ozone-depleting substances and synthetic greenhouse gases commonly been used for *?
Synthetic greenhouse gases are often used to replace ozone depleting substances in refrigeration, fire fighting and other systems.
Which of the following compounds is responsible for depleting the ozone layer Brainly?
Explanation: Chlorofluorocarbons (CFCs) and other halogenated ozone depleting substances (ODS) are mainly responsible for man-made chemical ozone depletion.
Which of the following is responsible for depletion of ozone layer?
chlorofluorocarbons
Freons are chlorofluorocarbons and are responsible for depletion of ozone layer.
Which products contain ozone depleting substances Mcq?
Is methane an ozone depleting substance?
Ozone-depleting substances are also very potent greenhouse gases, contributing to the phenomenon as other substances widely known to have a greenhouse effect like carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O).
