Stahl helped develop and popularize the phlogiston theory. Common use of oxygen includes residential heating, internal combustion engines, production of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, oxygen therapy, and life support systems in aircraft, submarines, spaceflight and diving. This article is about the chemical element and its most stable form, O. Rather than combustion or corrosion occurring as a result of the decomposition of phlogiston compounds into their base elements with the phlogiston being lost to the air, it is in fact the result of oxygen from the air combining with the base elements to produce oxides. But ozone is a pollutant near the surface where it is a by-product of smog. Conversely, oxygen is continuously replenished by photosynthesis, which uses the energy of sunlight to produce oxygen from water and carbon dioxide. For other uses, see Oxygen (disambiguation) and O2 (disambiguation). Another form ( allotrope ) of oxygen, ozone ( O.
Most of the mass of living organisms is oxygen as a component of water, the major constituent of lifeforms. This theory, while it was on the right track, was unfortunately set up backwards. Use these four tips from celebrity trainer Harley Pasternak to stay on track. Dioxygen is used in cellular respiration and many major classes of organic molecules in living organisms contain oxygen, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone. Gain Power and Strength With These Slam-Ball Exercises. Oxygen is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms. Promote Breast Health While Increasing Fullness and Firmness. For other forms of this element, see Allotropes of oxygen. Save 30% Off ALL Our Most Popular Fitness Classes. Read how a breakup catapulted Hi-Tech Pharmaceuticals and APS Nutrition fitness model Nay Jones into an Instagram star and full-time coach. Oxygen was discovered independently by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774, but Priestley is often given priority because his work was published first.
