." In many cases, an element may form more than one oxide. . . It is transported in large, insulated tanks. The chemical industry uses vast amounts of oxygen every year in a variety of chemical synthesis (formation) reactions. Chemistry: Foundations and Applications. For example, oxygen is used to burn off carbon and other impurities that are in iron to make steel. The carbon and other impurities are burned off in steel-making by blasting oxygen through molten iron. Oxygen has so many commercial, industrial, and other uses that it consistently ranks among the top five chemicals in volume of production in the United States. —A form of oxidation that occurs so rapidly that noticeable heat and light are produced. Oxygen also makes up about one-fifth of the Earth's atmosphere. The first of these is sometimes called nascent oxygen, and the last is more commonly known as ozone. Oxford: Oxford University Press, 2003. By comparison, nascent oxygen has only one atom per molecule. This did not make him a very popular man! There is strong evidence that certain synthetic chemicals, such as the freons and compounds known as the chlorofluorocarbons (CFCs) may be causing destruction of ozone molecules in the atmosphere. are called Type I and range from A, which is 99.0% pure, to F, which is 99.995% pure. Nearly all of the oxygen found on Earth today is produced by biological activity. Oxygen-18 is found in the environment. As life developed on Earth and photosynthesis became more common, the rate of production increased until the present concentration of oxygen in the atmosphere, the oceans, and the crustal rocks was reached about 580 million years ago. The presence of oxygen in drinking water is favourable, because it assists protective coating formation on the inside of metal water transp… Sulfur is carried back to Earth's surface as acid deposition when it rains or snows. The two discovered oxygen at nearly the same time in 1774, working independently of each other. When these two elements react in the shuttle's main engines, they provide a maximum thrust of 512,000 lb (232,000 kg). "Oxygen (revised) Nitrates, sulfates, and phosphates also contain oxygen and other elements. —A synthetic fuel that consists primarily of carbon monoxide and hydrogen gases. Encyclopedia.com. The discovery of oxygen is usually credited to Swedish chemist Carl Wilhelm Scheele (1742-86) and English chemist Joseph Priestley (1733-1804). Westport, CT: Greenwood Press, 2006. In high enough amounts, it can force the carbon monoxide out of the blood and cells can recover. Trefil, James. The parentheses indicate that nascent oxygen does not exist very long under normal conditions. Periodic sampling and analysis of the final product ensures that the standards of purity are being met. . During the dog days of summer my success dramatically fell. Merck. Oxygen is by far the most abundant element in the Earth 's crust. Oxygen also reacts with a number of compounds. This form of oxidation is known as decay. The adsorber contains zeolite and. In January 1998, the United States launched the Lunar Prospector satellite into orbit around the moon. The former allotrope is known as monatomic, or nascent, oxygen and the latter as triatomic oxygen, or ozone. It is critical since the allotrope has a tendency to absorb ultraviolet radiation that would otherwise be harmful or even fatal to both plant and animal life on the planet’s surface. As life developed on the Earth and photosynthesis became more common, the rate of production increased until the present concentration of oxygen in the atmosphere, the oceans, and the crustal rocks was reached about 580 million years ago. "Oxygen (revised) This limited oxygen supply was quickly depleted in the alpine lakes’ depths, making it so fish couldn’t live there. © 2019 Encyclopedia.com | All rights reserved. In events contested at sea level, such oxygen aids are not anything more than a placebo to the athlete; the lungs cannot absorb oxygen any more readily than if supplied by the air. The most abundant isotope, oxygen-18, is stable and available commercially. Oxford: Oxford University Press. Encyclopedia.com. It is the most abundant element in Earth's crust, making up about one-quarter of the atmosphere by weight, about one-half of the lithosphere (Earth's crust), and about 85 percent of the hydrosphere (the oceans, lakes, and other forms of water). This process produces oxygen that is 99+% pure. The environmental hazard posed by this series of reactions is that the level of ultraviolet radiation reaching the earth would be expected to increase as more and more ozone molecules are destroyed. ." water. —An abbreviation commonly used for liquid oxygen. Photosynthesis uses energy from the sun to split water into oxygen and hydrogen. Acid: Substances that, when dissolved in water, are capable of reacting with a base to form salts and release hydrogen ions. The two most common torches make use of the reaction between oxygen and hydrogen (the oxyhydrogen torch) or between oxygen and acetylene (the oxyacetylene torch). Ede, Andrew. . Individuals whose oxygen concentration in their blood is lower than normal often require an oxygen concentrator to replace that oxygen. I was puzzled because these alpine lakes contained colder water than their valley counterparts. Occurrence and preparation. World of Earth Science. When these two elements react in the shuttle's main engines, they provide a maximum thrust of 512,000 pounds. When most of the nitrogen is gone, argon and neon also boil off, leaving an impure form of oxygen behind. Kent, James A., editor. This confined the alpine lakes’ fish to the shallows while the valley lakes’ fish were in the lakes’ depths. As an example, the huge external fuel tank required to lift NASA’s space shuttle fleet into space holds 145,000 gal (550,000 l) of liquid oxygen and 390,000 gal (1,500,000 l) hydrogen. The most widely accepted theory says that solar radiation causes such chemicals to break apart, releasing a free chlorine atom to the stratosphere. Humans, for example, can go weeks and even months without food. 22 Dec. 2020 . engines. The three allotropes differ from each other in a number of ways. It shields out harmful radiation that comes from the Sun. Leonardo pointed out that air is not entirely used up when something is burned in it. He was an avid chemist who carried out many experiments. In each case, providing a person with pure oxygen reduces the stress on his or her heart and lungs, speeding the rate of recovery. In many cases, this "extra oxygen" keeps people alive after they would otherwise have died. Ethylene glycol is used in antifreeze and as a starting point in making polyester fibers, film, plastic containers, bags, and packaging materials. Immediately after Edison expired, his physician, put several of the tubes up to Edison's lips to catch the carbon dioxide from his deflating lungs. Oxygen diffusion occurs at the water’s surface, and its mixing throughout happens during a lake’s spring and fall turnover times. Some people think Scheele should get credit for discovering oxygen. The oxygen family consists of the elements that make up group 16 on the periodic table: oxygen, sulfur, selenium, tellurium, and polonium. Lavoisier eventually named the gas he studied oxygen from the Greek oxys meaning acid or sharp, and geinomial meaning forming. Most commercial oxygen is produced using a variation of the cryogenic distillation process originally developed in 1895. through an expansion valve instead of the second heat exchanger. For example, carbon monoxide poisoning occurs when carbon Oxygen is necessary for the survival of all animal life on Earth. Another metallurgical application of oxygen is in torches used for welding and cutting. Perhaps the best known medical application of oxygen is in oxygen therapy, where patients who are having trouble breathing are given doses of pure or nearly pure oxygen. The lower elevation lakes took in higher oxygen content during the spring and fall turnover times. Fly Fishing: The Lifetime Sport. In many instances, oxygen is manufactured at the location where it will be used. Oxygen is a non-metal in group 16 of the periodic table . So, they say, it contains both carbon dioxide and oxygen? This liquid nitrogen stream is then fed back into the low-pressure column to provide the additional cooling required to liquefy the oxygen as it sinks to the bottom of the column. Its melting point is 450°C (842°F), and its boiling point is 990°C (1,814°F). The properties of the Chinese yin and yang can be compared to the properties of oxygen and nitrogen. But Marat was now a very powerful man. Owners of oxygen bars say that city air is often too polluted. Oxygen can also be produced as the result of a chemical reaction in which oxygen is freed from a chemical compound and becomes a gas. When an electrical current is passed through water to which a small amount of inorganic acid has been added, water molecules break apart to form hydrogen gas and oxygen gas. Liquid air is made by cooling normal atmospheric air to very low temperatures. Rainey was found guilty of resisting arrest in 2014, and again in 2016, court records obtained by Oxygen.com show.. Of course, they pay a fee for the privilege. Lane, Nick (2002). The human body is about two-thirds oxygen. People come to breathe pure oxygen for a few minutes. Its name comes from the French word for "acid-former," reflecting Lavoisier's incorrect belief that all acids contain oxygen. The oxygen is impure because small amounts of krypton, xenon, and other gases may remain in the liquid form. Chemistry: Foundations and Applications. Under most circumstances, heating a hydrocarbon with oxygen results in combustion, with carbon dioxide and water as the main products. However, its liquid and solid state are blue. It is located in period 2 and group 16. Inhaled oxygen passes through the sac wall to directly enter the cardiovascular system, and waste carbon dioxide passes out into the lung. It is a colorless, odorless, tasteless gas that is the most plentiful element in Earth’s atmosphere and is a constituent of all living matter. Five radioactive isotopes of oxygen are known also. Oxygen first appeared in the Earth’s atmosphere around 2 billion years ago, accumulating from the photosynthesis of blue-green algae. In its most common form, oxygen is a colorless gas found in air. Although English chemist Joseph Priestley (1733–1804) is generally credited with the discovery of oxygen in 1774, many science historians contend that Swedish chemist Carl Scheele (1742–1786) probably discovered oxygen a few years prior to Priestly. It changes to a liquid at a temperature of -111.9°C (-169.4°F) and from a liquid to a solid at -193°C (-135°F) . The oxidation state of oxygen is −2 in almost all known compounds of oxygen. Some water purification and sewage treatment plants use oxygen. In many cases, the reaction between oxygen and another element is highly exothermic. ." Its symbol is O, the atomic weight is 15.9994, the specific gravity is 1.10535 (compared to air), the melting point is -361°F (-218.4°C), and the boiling point is -297.4°F (-183°C). In response to this threat, most of the world’s nations have agreed to reduce the amount of freons, CFCs, and other ozone-depleting chemicals produced and sold each year. Oxygen has been found in Mars' atmosphere, but before you go thinking about moving to the first Mars colony, there are a few things you should know. Some of the most beautiful colored glasses, ranging from pale pink to brilliant reds, are made with compounds of selenium. The density is 2.144 grams per liter. By carefully distillation of the liquid air, the various component gases could be boiled off one at a time and captured. Chemical Elements: From Carbon to Krypton. When iron and certain other metals are exposed to oxygen (in the presence of water), they form oxides. Radioactive decay: The predictable manner in which a population of atoms of a radioactive element spontaneously disintegrate over time. The oxygen diffusion process is very slow. In his classic experiment, for example, Priestley heated red oxide of mercury (mercuric oxide; HgO) and found that he obtained liquid mercury and a new gas: 2HgO—heat → 2Hg + O2. New York: Oxford University Press, 2002. The ozone layer has recently been the subject of intense scientific interest to determine whether, and to what extent, it may be deteriorating, mainly from pollutants in the atmosphere. Lane, Nick. Retrieved December 22, 2020 from Encyclopedia.com: https://www.encyclopedia.com/science/encyclopedias-almanacs-transcripts-and-maps/oxygen-1. ." Sulfur is produced naturally as a result of volcanic eruptions and through emissions from hot springs. The Oxford Companion to the Body. Lavoisier chose the name because he thought that all acids contain oxygen. For example, some Chinese scholars, as early as the eighth century a.d., thought of air as having two parts. In order to further purify the oxygen, the process of cooling, liquefying, and evaporation may be repeated. World of Sports Science. The oxygen passes into the atmosphere and the hydrogen joins with carbon dioxide to produce biomass. For example, it is used in rocket fuels. The energy is used to lift the rocket into space. Another container can be put into place. This results in areas where fish can and cannot live. The sulfur is extracted from these mines by means of the Frasch process. Oxygen is the chemical element with the symbol O and atomic number 8. The reaction between oxygen and another element generally results in the formation of a binary compound known as an oxide. It is said to contain the last breath of Thomas Alva Edison, the great inventor. Air fit that description, along with fire, water, and earth. . In many cases, an element may form more than one oxide. Ancient peoples thought deeply about that question. The element was given its name in the late 1770s by French chemist Antoine Laurent Lavoisier (1743–1794). Others are metal sulfides, including iron pyrites (iron sulfide, FeS2), galena (lead sulfide, PbS), cinnabar (mercuric sulfide, HgS), stibnite (antimony sulfide, Sb2S3), and zinc blende (zinc sulfide, ZnS). Among its many tasks, this satellite will be scanning the surface of the moon for indications of water. Lavoisier voted against Marat's application. Some people have said that Lavoisier's death was the worst single consequence of the French Revolution. Although ozone is toxic to breathe, the 0.12 in (3 mm) thick layer of ozone in the earth's atmosphere provides a shield from harmful ultraviolet rays from the Sun. During high temperature times, the whitewater river sections mix higher oxygen content. Oxygen is the third most abundant element found in the Sun , after hydrogen and helium, and plays an important role in the carbon-nitrogen cycle. "Oxygen Missy And Michael MacIvor Found Dead In Their Home oxygen Insider Exclusive! ." Oxygen is then used in a second step of iron processing in the Bessemer converter, open hearth, or basic oxygen process method of converting pig iron to steel. I neglected to take into account the difference in altitude and atmospheric pressure between the alpine and valley lakes. Retrieved December 22, 2020 from Encyclopedia.com: https://www.encyclopedia.com/manufacturing/news-wires-white-papers-and-books/oxygen. The elements in Group 16 are said to belong to the chalcogen family. Oxygen is by far the most abundant element in the Earth's crust. Newer cryogenic distillation units are designed to recover more of the argon from the low-pressure column, and this improves the oxygen purity to about 99.8%. Sulfur itself has no odor at all. Priestley described his discovery to the French scientist Antoine Lavoisier, who experimented further and determined that it was one of the two main components of air. According to Edison's son Charles, a set of eight empty test tubes sat on the table next to Edison's deathbed in 1931. It has a natural abundance of 0.2 percent. Oxygen has so many commercial, industrial, and other uses that it consistently ranks among the top five chemicals in volume of production in the United States. Note: This article, originally published in 1998, was updated in 2006 for the eBook edition. As an example, the huge external fuel tank required to lift the space shuttle into space holds 145,000 gal (550,000 l) of liquid oxygen and 390,000 gal (1,500,000 l) hydrogen. https://www.encyclopedia.com/science/encyclopedias-almanacs-transcripts-and-maps/oxygen-1, "Oxygen Finally, oxygen is essential to all animal life on Earth. That is, a rise in altitude lowers the atmospheric pressure, and a decrease in altitude raises the atmospheric pressure. One of the best known of such reactions is the one that takes place between carbon and oxygen, to form (usually) carbon dioxide and carbon monoxide. In some operations, the air may be cooled by passing it She has taught science courses at the high school, college, and graduate levels. Chemical Elements: From Carbon to Krypton. Acclimatization spurs the production of a hormone in the kidneys known as erythropoietin (EPO), which is the chemical signal to the body to produce a greater number of erythrocytes (red blood cells) to counter the effect of less oxygen; if there is less oxygen available to be transported, the greater number of red blood cells can more efficiently acquire what available oxygen there is to be consumed. In a related way, the goal of enhanced oxygen transport has been the reason for the development of synthetic versions of EPO, used as the primary blood-doping agent. It helps them get their energy back. The physical properties of ozone are somewhat different from those of dioxygen. Many of these are in the form of sulfates, including gypsum (calcium sulfate, CaSO4), barite (barium sulfate, BaSO4), and Epsom salts (magnesium sulfate, MgSO4). The products of decay are mainly carbon dioxide (CO2) and water (H2O):(The chemical formula for "dead matter" is too complicated to use here.). Encyclopedia.com. Copper, as an example, forms both copper(I) (cuprous) oxide and copper(II) (cupric) oxide. I t is produced when gasoline is burned in cars and trucks. Nearly all of the oxygen found on the Earth today is produced by biological activity. The name chalcogen comes from the Greek word chalkos, meaning "ore." The first two members of the family, oxygen and sulfur, are found in most ores. Encyclopedia.com. . The primary uses of selenium are in electronics and in the manufacture of colored glass. Scientists hope that if sufficient quantities of water are found, it could be used to produce hydrogen and oxygen gases through electrolysis, using solar power to generate the electricity. Inorganic materials also react slowly with oxygen. Radioactive isotopes are produced when very small particles are fired at atoms. Then, the physician carefully sealed each tube with paraffin and gave the tubes to Charles Edison. Insufficient oxygen supplies will result in animal death. The liquid air is then allowed to evaporate. Other impurities removed by a blast of oxygen are sulfur, phosphorus, manganese, and other metals. "Oxygen The first is by far the most abundant, constituting 99.763% of all oxygen atoms occurring in nature. "Oxygen Family The name chalcogen comes from the Greek word chalkos, meaning "ore." The first two members of the family, oxygen and sulfur, are found in most ores. The element oxygen is essential to all human life. In either case, the temperature of the air is lowered to the point where the oxygen, which has the highest. Hawley, Gessner G. The Condensed Chemical Dictionary. Oxygen was discovered in 1774 by Joseph Priestley in England and two years earlier, but unpublished, by Carl W. Scheele in Sweden. Oxygen is the most abundant element on the Earth's surface. One of these enemies was Jean-Paul Marat (1743-93). 22 Dec. 2020 . Auto exhaust, poorly maintained oil furnaces, and wood fires produce carbon monoxide. Oxygen is also the most abundant element in the Earth's crust. . Within the lung cavity, there are tiny, thin-walled alveoli, air sacs that are connected to the wall of the lung and which are each a part of a dense network of capillaries, the blood vessels that act as exchange mechanisms. Charles Edison knew that Henry Ford's idol was Thomas Edison and presented Ford with one of the tubes as a keepsake. The oxygen is impure because small amounts of krypton, xenon, and other gases may remain in the liquid form. Since a lake depends upon wave action, photosynthesis, and currents to mix and produce its oxygen, areas of adequate and inadequate oxygenated water exist simultaneously. Most online reference entries and articles do not have page numbers. Oxygen-17 makes up an additional 0.037%, and oxygen-18, 0.200% of all oxygen atoms. A sample of air is first cooled to a very low temperature in the range of −200°C (−330°F). It is one of the life-sustaining elements on Earth and is needed by all animals. Encyclopedia.com. Lavoisier led an unusually interesting life. see also Blood doping; Cardiorespiratory function; EPO; Glycogen depletion. Aircraft that fly at high altitudes, of course, are always provided with supplies of oxygen in case of any problems with the ship’s normal air supply. His description of that experience has now become famous: A ntoine-Laurent Lavoisier (1743-94) is often called the father of modern chemistry. Oxygen is the third most abundant element in the universe and makes up nearly 21% of the earth's atmosphere. Oxygen: The Molecule that Made the World. Standard oxygen is colorless, tasteless, and has no odor. Lithosphere: The solid portion of Earth, especially the outer crustal region. About one-half of the earth's crust is made up of chemical compounds containing oxygen, and a fifth of our atmosphere is oxygen gas. Retrieved December 22, 2020 from Encyclopedia.com: https://www.encyclopedia.com/science/news-wires-white-papers-and-books/oxygen-revised. When plants and animals die, for example, the organic materials of which they are made slowly react with oxygen in the atmosphere. It is considerably more soluble in some organic solvents, such as ethyl alcohol , carbon tetrachloride , and benzene . Some common instances in which oxygen therapy is used include surgical procedures, following heart attacks, and during infectious diseases. One of the disturbing aspects of this theory is that it suggests that a single chlorine atom can cause the decomposition of many thousands of ozone molecules. Producer gas, as an example, is manufactured by passing oxygen at a controlled rate through a bed of hot coal or coke. Small amounts of tellurium are also used in the production of colored glass. The majority of carbon dioxide produced in this reaction is reduced to carbon monoxide so that the final product (the producer gas) consists primarily of carbon monoxide and hydrogen. That chlorine atom then reacts with ozone molecules, converting them into diatomic oxygen molecules. For example, the oxidation reaction between oxygen and sodium produces sodium oxide. It was difficult for them to collect samples of air and then to study it. Oxygen is the most abundant element on the Earth’s surface. Oxygen is commonly stored and transported in its liquid form, a form also known as LOX. As Markarian is a starburst galaxy, undergoing furious star formation, this could be possible. 1 The air is compressed to about 94 psi (650 kPa or 6.5 atm) in a multi-stage compressor. In 1988, for example, 37 billion lb (16.8 billion kg) of the element were manufactured in the United States. Lide, D.R., ed. New York: Van Nostrand Reinhold Company, 9th ed, 1977. At -182.96°C (-297.33°F), oxygen changes from a gas into a liquid. That makes it almost twice as abundant as the next most common element, silicon. The deeper shaded areas just above the thermocline can be cool enough to hold sufficient oxygen. In this step, the oxygen is used to react with the excess carbon, silicon, and metals remaining in the pig iron that must be removed in order to produce steel. Oxford: Oxford University Press, 2002. Cavette, Chris "Oxygen I once thought that all big fish lived in the depths and only small ones were in the shallows. Water contains 88.9% oxygen, by weight. That step was taken by French chemist Antoine-Laurent Lavoisier (1743-94). And so on. In higher concentrations, however, the element has been found to have harmful effects on animals, causing deformed young and diseased adults. The human body ingests oxygen primarily through the respiratory system, with the cardiovascular system the vehicle by which oxygen is then transported for uses throughout the body.
