Answers
Answer:
The answer is C. CFCsfrom cleaning and cooling materials combine with other molecules in the air, harming Earth’s protective ozone layer.
Explanation:
Chlorofluorocarbonsand (CFCs) halons destroy the earth's protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate. Hydrofluorocarbons (HFCs) also act to warm the planet. The Minnesota Pollution Control Agency (MPCA) is working with industry, residents and government to reduce the damage done to the ozone layer and global climate by CFCs, HCFCs, HFCs and related chemicals.
The CFC is actually chlorofluorocarbon, released from the cooling material. It harms the protective Ozone layer of the earth. Thus Option C is correct.
How is CFC involved in chlorine production ?The Chloro fluoro carbon reacts with the other substances in the presence of sunlight and due to this, there is a release of chlorine in the environment.
The role of chlorine is that when it enters the stratosphere, It starts breaking down the ozone and itself combines with oxygen and in this way creates two free oxygen.
So, the chlorine molecule basically acts as a catalyst as in each reaction it acts in the same way and damages the ozone layer with the above-mentioned reaction.
Thus, option C is correct, as CFC, which has chlorine as its constituent molecule when released in the stratosphere region initiates the breakdown reaction of Ozone.

questions in the pictureeeee
Answers
1. There is alcohol and drugs at a party and you do not want to consume alcohol or use drugs.
2. You could avoid the areas/people consuming alcohol and/or using drugs. You could hang out with people at the party that are not using alcohol or drugs. Walk away from the situation if someone offers you drugs/alcohol by using excuses like "sorry, I need to go find ....... right now" or "I've been taking medication so I can't." Being assertive is another option - you can tell them directly and confidently that you don't want to take drugs/alcohol.
3. Avoiding certain people could result in conflict if they notice you are purposefully avoiding them. Making excuses with dishonesty could get you in trouble if someone catches you in a lie and they could approach you later on and ask again. Being assertive can make them have a negative view of you.
4. Think about what would be safest for you and those around you. Being assertive would work most quickly and effectively. Tell the person directly but politely that you can't take drugs or consume alcohol. If you can provide an honest reason e.g. "parents won't let me" or "my parents are picking me up and I'd rather not risk it", then that'd be better.
5. After evaluation, it's possible some may disagree with your decision but your goal was to have a safe, fun and sober night out - this goal was achieved.
