1. Which of the following were found to destroy ozone in the upper atmosphere?
All of these: 1.sulfur oxides 2.CFCs (actually just the chlorine atom(s) stripped from this) 3.nitrogen oxides Mars' entire complement of ozone (ain't much) is made by stripping oxygen from this: 4.carbon dioxide
Chloroflourocarbons are broken down in the upper atmosphere to produce oxygen o2?
technically yes, Ozone can be destroyed by a number of free radical catalysts, the most important of which are the hydroxyl radical (OH·), the nitric oxide radical (NO·), the atomic chlorine ion (Cl·) and the atomic bromine ion (Br·). All of these have both natural and man-made sources; at the present time, most of the OH· and NO· in the stratosphere is of natural origin, but human activity has dramatically increased the levels of chlorine and bromine. These elements are found in certain stable organic compounds, especially chlorofluorocarbons (CFCs), which may find their way to the stratosphere without being destroyed in the troposphere due to their low reactivity. Once in the stratosphere, the Cl and Br atoms are liberated from the parent compounds by the action of ultraviolet light, e.g. ('h' is Planck's constant, 'ν' is frequency of electromagnetic radiation) CFCl3 + hν → CFCl2 + Cl The Cl and Br atoms can then destroy ozone molecules through a variety of catalytic cycles. In the simplest example of such a cycle,[4] a chlorine atom reacts with an ozone molecule, taking an oxygen atom with it (forming ClO) and leaving a normal oxygen molecule. The chlorine monoxide (i.e., the ClO) can react with a second molecule of ozone (i.e., O3) to yield another chlorine atom and two molecules of oxygen. The chemical shorthand for these gas-phase reactions is: Cl + O3 → ClO + O2 in the decomposition it produces Chlorine and other bromines in a chemical reduction of 03 to 02. ClO + O3 → Cl + 2 O2 ------ Produce is a nebulous term, changing Ozone into atmospheric oxygen CFC's do this. Saying flatly no, is not correct. in terms of the technical/chemical impact of CFC it does take 03 and changes to Chlorine and O2
What is the function of ozone in the upper atmosphere?
Ozone is made up of three atoms of oxygen. High concentration of ozone is found in the upper part of the Stratosphere.Role of Ozone :It protects from harmful ultraviolet (UV) rays from the Sun.In the absense of it would be very difficult for anything to survive on the surface.In the absense of ozone plants cannot live and grow in heavy ultraviolet radiation.In the absence of ozone plankton cannot survive which serve as food for most of the ocean life.It helps to maintain heat balance on earth.
If there is no ozone gas in the atmosphere, what would happen on the Earth's surface?
there's already a layer of natural sunscreen at work. And without it, she wouldn't be able to go into the sunlight without it burning her skin almost immediately.This natural sunscreen, known as Earth's ozone layer, absorbs and blocks the majority of the sun's UV radiation.Without this barrier in place, all of the radiation would reach Earth, damaging the DNA of plants and animals, like us humans. Skin cancer rates would soar, but we might not even live long enough to experience that cause of death [source: Carlowicz].Within days of the ozone layer's disappearance, many plants would die. The intensity of the sun's radiation would make photosynthesis — a process by which plants convert light energy into chemical energy to fuel their growth — an impossibility for all but the largest and slowest-growing florae. And even these holdouts, primarily massive trees, would eventually die, too. Without plants, the food chain would collapse. Herbivores would starve. Omnivores and carnivores could feed off their bodies for a time, but their food supply would dwindle and cause widespread extinction [source: Vermaas].https://science.howstuffworks.co...
What would happen to the Earth if the ozone layer were destroyed?
Our natural sunscreen, known as Earth's ozone layer, absorbs and blocks the majority of the sun's UV radiation. Without this barrier in place, all of the radiation would reach Earth, damaging the DNA of plants and animals, like us humans.

Omnivores and carnivores could feed off their bodies for a time, but their food supply would dwindle and cause widespread extinction.So where is the ozone layer, exactly, and how does it work? A layer of ozone gas acts as a shield encircling Earth, and exists between 9.3 (15 kilometers) to 18.6 miles (30 kilometers) above its surface. As one might suspect, the ozone layer is filled with ozone, also known as [math]O_3[/math][math] [/math]or trioxygen. Ozone is created when oxygen molecules ([math]0_2[/math]) are split by the sun into a duo of free-ranging oxygen atoms. When one of these free atoms bonds with an [math]0_2 [/math]molecule, an [math]0_3 [/math]molecule -- ozone -- is created.Despite its protective powers, ozone isn't necessarily stable, and it doesn't take much to reduce ozone to its base elements. Take chlorofluorocarbons (CFC's), for example. When these synthetic chemicals, once used as refrigerants and aerosol-spray propellants, travel to the upper atmosphere they begin a chain reaction that spells disaster for the ozone layer. The CFC's are broken down by ultraviolet light and, as a result, release free chlorine atoms that attract oxygen atoms from ozone molecules. And what happens when you take an oxygen atom from ozone? It becomes oxygen. In this way, CFC's can make quick work of the ozone layer, which is why they have been placed under ever-tightening regulations over the past several decades, with a goal of eliminating their use completely later this century.So, I request everyone to do WHATEVER is in your right to save ozone.Reference To: howstuffworks, Google
How do I calculate liters of one gas destroyed in order for a reaction with another?
This is the problem I'm stuck on: -Chlorine in the upper atmosphere can destroy ozone molecules, O3. The reaction can be represented by the following equation Cl2(g) + 2O3(g) --> 2ClO(g) + 2O2(g) -How many liters of ozone, O3, can be destroyed at 220K and .0650 atm if 150g of chlorine gas react with it?
Why are we losing our ozone layer?
The hole in the ozone layer is seasonal. Ozone is formed when an oxygen molecule (O2) in the stratosphere absorbs ultraviolet energy from the Sun and breaks into 2 oxygen molecules which then each combine with other oxygen molecules to form O3. When struck by the Suns radiation the ozone molecule is destroyed and reverts back to oxygen molecules. This is why, during winter months, the south and north poles have a decrease in ozone concentration. Because there is no sunlight. During summer months the ozone hole rebounds because there is sunlight to create those ozone molecules. The ozone hole is labeled as such because it is a area of ozone that falls below 220 Dobson Units. There are, however, different chemical reactions that can steal one of the Oxygen molecules from an Ozone molecule (O3) and turn it back into Oxygen (O2) such as those reactions with CFCs, N2O and other chemicals, many of which are released by human technology.
What's the difference between Global warming and Ozone depletion?
Global warming is the blocking of infrared light from the ground from escaping to space increasing the temperature of the planet due to more greenhouse gasses in the air, primarily carbon dioxide. Ozone depletion is the reduction of ozone in the upper atmosphere that would normally screen out ultra violet light that can cause sunburns and skin cancer. It is caused by chlorine compounds, like Freon, causing the ozone to break down.
