This can be used for medical uses but also athletic performance. Compounds of oxygen, however, are very common in nature and in industry. However, most citizens still consider air/oxygen purifiers to be prohibitively expensive, so they simply wear a flu mask to mitigate the negative effects of pollution on the human body. [4], 6. Luckily, the body maintains a supply of antioxidants to combat day-to-day oxidative stress. Nearly of our body weight is oxygen! Oxygen (after hydrogen and helium) is the third most abundant element in the universe. This showed that plants produce a gas that allows fuels to burn, and this gas is oxygen. A single tree produces 260 pounds of oxygen per year. You may not know it, but oxygen is all around you, all the time. Based on reports, customers have two options: pure oxygen, which contains 97% oxygen and a small number of other gases, or fresh clean air, which contains 78 percent nitrogen, 21 percent oxygen, and a small number of other gases. It is still the primary combustor in rocket fuel today. In addition, oxygen forms covalent oxides with non-metals, which react with water to form acidic solutions. Here are some quick facts about this important element. Without the Ozone Layer of the earths atmosphere, the UV index at the surface would be far too high for living organisms to thrive. Oxygen is a colourless, odourless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere. 10 Interesting Things About Air Air is mostly gas. Fact #16. Without life, our atmosphere would contain almost no O2. Because water has a higher concentration of oxygen than the gills, fish can extract oxygen from the ocean using their gills. As a compound, oxygen can be found in water, plants, animals, and in much of the solid material that makes up the earth. At normal pressure, oxygen poisoning occurs when the gas exceeds 50%. Oxygen-17 is made during the CNO cycle when hydrogen is burned into helium. It is strongly paramagnetic as a result of the parallel spin of unpaired electrons. 8.
