Name: A chemical used to deplete ozone layer. View Solution Ozone is an unstable, dark blue diamagnetic gas. It absorbs strongly the UV radiation, thus proteching the people on the earth from the harmful UV radiation from the sun. The use of chloroflurocarbon (CFC) in aeroslos and refrig...
If you look closely at our top photo, you can see that the fan has a green "Ozone friendly" label on it, which means there are no CFC coolants inside. Here to stay? Love them or loathe them, we won't be getting rid of our air conditioners anytime soon; in the United States, ...
a不是。我是骑士,拿大剑。哦耶! .I am a knight, takes the big sword.Oh Ye![translate] a许多旧冰箱和汽车危害环境,因为它们含有的CFC会破坏臭氧层 Many old refrigerators and automobile harm environment, because they include CFC can destroy the ozone layer[translate] ...
Do not drink pool water. Disease can be spread through contaminated pool water. Refrigerant recovery units remove an air conditioner's refrigerant. All CFC and HCFC refrigerants destroy ozone. Because of this the Environmental Protection Agency (EPA) has required the eventual elimination of these typ...
Explain how the Lewis structure of ozone is important. What can chemists can do to prevent ozone depletion in the atmosphere?Ozone Layer:One cannot imagine the protection of human beings from harmful solar radiations in the absence of ozone laye...
In 1987 the Montreal Protocol was introduced and later signed up to by 120 countries who agreed to half their CFC emissions by the year 2000. We now know that apart from destroying the ozone layer, CFCs contribute significantly to the greenhouse effect. Even though they have been banned, ...
All CFC and HCFC refrigerants destroy ozone. Because of this the Environmental Protection Agency (EPA) has required the eventual elimination of these types of refrigerants. By the year 2020 all HCFC and CFC refrigerants available for use will come from old systems that have had the refrigerant re...
Even if the CFC production has been reduced or cut at zero in almost every nation by now, we will have to wait until the end of the next decade to have restored the ozone layer to 1975 values due to the long residence time of CFC's in the environment.2 2.2. The ecological point of...
This agreement brought EPF to the world's consciousness as a threat to the ozone layer. While foam packaging is responsible for less than three percent of the CFCs being released into the atmosphere, EPF reduction has been targeted as a way to lower CFC levels, and new technology that ...
What environmental problems do they cause? Identify at least two pollutants that destroy the ozone layer. Discuss the origination of these pollutants and a plan for reduction. Why does most of the 'usable' water get withdrawn from the groundwater? Whi...
