Some sulfur is used directly as a fungicide and insecticide, in matches, fireworks, and gunpowder, and in the vulcanization of natural rubber (a treatment that gives rubber elasticity and strength). It also exists in another allotropic form, the triatomic molecule ozone (O3). Water harbors a tenuous margin of safety because its oxygen content is small and varies widely. Oxygen: The Molecule That Made the World. However, if the rate at which oxygen is fed into a hydrocarbon mixture is carefully controlled, the hydrocarbon is cracked, or broken apart, to produce other products, such as acetylene, ethylene, and propylene. Water contains 88.9% oxygen, by weight. He has been given that title for a number of reasons. Both wind and wave actions mix oxygen at the surface, while plant photosynthesis generates oxygen when plants are present. This technique became a common industrial method of welding and cutting metals. Metallurgy: The science and technology that deals with gaining metals from their ores and converting them into forms that have practical value. Greenwood, N.N., and A. Earnshaw. Ancient peoples thought deeply about that question. Lavoisier also made some important enemies early in his life. Oxygen can be prepared on a small scale by the decomposition of oxygen-containing compounds. In many cases, this "extra oxygen" keeps people alive after they would otherwise have died.

It is then cooled and allowed to expand to nearly atmospheric pressure. Chemistry: Foundations and Applications. Lavoisier showed that this idea was incorrect. They are used in steel making and in the manufacture of synthetic chemicals. Oxygen is a non-metallic element of atomic number 8. Oxygen is made from liquid air. So, they say, it contains both carbon dioxide and oxygen? As Markarian is a starburst galaxy, undergoing furious star formation, this could be possible. It tends to break down and form dioxygen: Ozone does occur in fairly large amounts under special conditions. For example, the oxidation reaction between oxygen and sodium produces sodium oxide. The incoming air stream is cooled, while the oxygen and nitrogen are warmed. The uses to which oxygen is put can be classified into four major categories: metallurgy, rocketry, chemical synthesis, and medicine. Ozone —An allotrope of oxygen that consists of three atoms per molecule. This process produces carbon dioxide and water vapor, which are then captured and removed.

Oxygen solubility in water increases with decreases in both temperature and altitude. In air the lack of oxygen is rarely a problem, but in water its effect is more apparent. One of the most important of these is the cracking of hydrocarbons by oxygen. The carbon monoxide, in turn, reduces iron oxides to pure iron metal . This is why a lake’s greatest depths can become so oxygen poor. During respiration, animals and some bacteria take oxygen from the atmosphere and return to it carbon dioxide, whereas by photosynthesis, green plants assimilate carbon dioxide in the presence of sunlight and evolve free oxygen. The process of fractional distillation described earlier is sufficiently simple and inexpensive so that many industries can provide their own oxygen-production facilities. Hydrogen and oxygen can be generated by passing an electric current through water and collecting the two gases as they bubble off. Periodic sampling and analysis of the final product ensures that the standards of purity are being met. The chemical formula is O3. Patrons say that pure oxygen makes them feel better and think more clearly. The silicon dioxide (SiO2) forms slag. But they used the word "element" differently than do modern scientists. There are three naturally occurring isotope of oxygen: oxygen-16, oxygen-17, and oxygen-18. (December 22, 2020). When its temperature reaches -195.79°C, liquid nitrogen changes back to a gas. Uses of sulfur and its compounds. Oxygen composes 21% of Earth's atmosphere by volume and is vital to the existence of carbon-based life forms. It occurs naturally in uranium ores, where it is the final product in the long series of reactions by which uranium undergoes radioactive decay. Almost all the free oxygen in the atmosphere is due to photosynthesis. Oxygen is the eighth element of the periodic table and can be found in the second row (period). For example, the huge external fuel tank required to lift the space shuttle into space holds 550,000 liters (145,000 gallons) of liquid oxygen and 1,500,000 liters (390,000 gallons) of liquid hydrogen. Decay is the process by which once-living material combines with oxygen. The oxygen is impure because small amounts of krypton, xenon, and other gases may remain in the liquid form. Nature’s Building Blocks: An A-Z Guide to the Elements. Oxygen is the most abundant of all elements found in nature. He was also the first person to explain how oxygen is involved in burning. Encyclopedia of Science and Technology. The Oxford Companion to the Body. Five radioactive isotopes of oxygen are known also. Its melting point is 450°C (842°F), and its boiling point is 990°C (1,814°F). It is found in the upper atmosphere, and there it is helpful. Under ordinary conditions (STP) on Earth, oxygen is a colorless, odorless, tasteless gas that is only slightly soluble in water. Oxygen is a colorless, diatomic gas in pure form at normal temperature and pressure. How or from whom do Hospitals get the oxygen they provide to patients and have available in all room Ken W 4 years ago. The oxygen atom is a part of hydroxyl, carbonyl, and other functional groups. A container can be put into place to catch the nitrogen as it boils off the liquid air. Copper , as an example, forms both copper(I) (cuprous) oxide and copper(II) (cupric) oxide. It is one of the life-sustaining elements on Earth and is needed by all animals. The first step in recovering these metals is to convert them to oxides: The oxides are then heated with carbon to make the pure metals: Another use of oxygen is in high-temperature torches. The solid changes color as temperature is lowered and pressure is increased, eventually becoming orange, red, black, and finally metallic. The combustion (burning) of charcoal is an example. Sulfur itself has no odor at all. Chemists show this by writing the formula as O2. 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. But they cannot use carbon monoxide, so they begin to die. In addition, oxygen is thought to be the third most abundant element in the universe and in the solar system. None of the radioactive isotopes of oxygen has any commercial use. The element can also be produced by the electrolysis of water. Oxygen is less soluble in sea water than in pure water, although still soluble enough to support the survival of marine organisms. 22 Dec. 2020 . Oxygen accounts for nearly half of the mass of the earth's crust, two thirds of the mass of the human body and nine tenths of the mass of water. through an expansion valve instead of the second heat exchanger. Oxygen is one of the atoms that makes up water (H 2 O). Retrieved December 22, 2020 from Encyclopedia.com: https://www.encyclopedia.com/manufacturing/news-wires-white-papers-and-books/oxygen. xford: Oxford University Press, 2003. ." Some sulfur is used directly as a fungicide and insecticide, in matches, fireworks, and gunpowder, and in the vulcanization of natural rubber (a treatment that gives rubber elasticity and strength). It also exists in another allotropic form, the triatomic molecule ozone (O3). Water harbors a tenuous margin of safety because its oxygen content is small and varies widely. Oxygen: The Molecule That Made the World. However, if the rate at which oxygen is fed into a hydrocarbon mixture is carefully controlled, the hydrocarbon is cracked, or broken apart, to produce other products, such as acetylene, ethylene, and propylene. Water contains 88.9% oxygen, by weight. He has been given that title for a number of reasons. Both wind and wave actions mix oxygen at the surface, while plant photosynthesis generates oxygen when plants are present. This technique became a common industrial method of welding and cutting metals. Metallurgy: The science and technology that deals with gaining metals from their ores and converting them into forms that have practical value. Greenwood, N.N., and A. Earnshaw. Ancient peoples thought deeply about that question. Lavoisier also made some important enemies early in his life. Oxygen can be prepared on a small scale by the decomposition of oxygen-containing compounds. In many cases, this "extra oxygen" keeps people alive after they would otherwise have died. The hydrogen could be used as a fuel, and the oxygen could be used to provide life support for lunar colonies. Priestley heated mercury oxide, focusing sunlight using a 12-inch ‘burning lens’ – a very large magnifying glass – to bring the oxide to a high tem… French chemist Antoine Lavoisier's (1743–1794) contributions to the study of the important reactions, combustion and oxidation, were spurred by the discovery of oxygen. Retrieved December 22, 2020 from Encyclopedia.com: https://www.encyclopedia.com/science/news-wires-white-papers-and-books/oxygen-revised. "Oxygen Oxygen is by far the most abundant element in the Earth 's crust. UXL Encyclopedia of Science. In this process, superheated steam is pumped through the outermost of a set of three pipes. "Oxygen Family 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. It enters the atmosphere primarily in the form of sulfur dioxide, then remains in the atmosphere in that form or, after reacting with water, in the form of sulfuric acid. —An allotrope of oxygen that consists of three atoms per molecule. 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. Its atomic number is 7 and it is denoted by the symbol ‘N’ in the periodic table. 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. . Oxygen is also used in the chemical industry as a beginning material in making some very important compounds. ." Encyclopedia.com. In order to further purify the oxygen, the process of cooling, liquefying, and evaporation may be repeated. And that should not be surprising. She has taught science courses at the high school, college, and graduate levels. . Cavette, Chris "Oxygen Both Rainey and Church have extensive arrest records. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates. The most important reason is the explanation he discovered for the process of combustion (burning). 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. Oxygen is the chemical element with the symbol O and atomic number 8. The oxygen diffusion process is very slow. The escaping oxygen can be collected. When plants and animals die, for example, the organic materials of which they are made slowly react with oxygen in the atmosphere. Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. see also Blood doping; Cardiorespiratory function; EPO; Glycogen depletion. Oxygen exists in three allotropic forms, monatomic oxygen (O), diatomic oxygen (O2), and triatomic oxygen (O3). Oxygen is also used in many industrial, commercial, medical, and scientific applications. "Oxygen Producer gas: A synthetic fuel that consists primarily of carbon monoxide and hydrogen gases. The discovery of polonium in 1898 by Polish-French chemist Marie Curie (1867–1934) is one of the most dramatic stories in the history of science. Retrieved December 22, 2020 from Encyclopedia.com: https://www.encyclopedia.com/science/encyclopedias-almanacs-transcripts-and-maps/oxygen-0. It is located in period 2 and group 16. Finally, oxygen is essential to all animal life on Earth. That chlorine atom then reacts with ozone molecules, converting them into diatomic oxygen molecules. In the absence of oxygen, energy-generating chemical reactions taking place within cells would come to an end, and a person would die. Its name comes from the French word for "acid-former," reflecting Lavoisier's incorrect belief that all acids contain oxygen. One problem was that early chemists did not have very good equipment. . . Encyclopedia of Chemical Technology, 4th edition. Most commercial oxygen is produced in air separation plants. 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. Oxygen is the 8th element on the periodic table. ." Selenium and tellurium are both relatively rare elements. Oxygen, in the form of LOX, is widely used as the oxidizing agent in many kinds of rockets and missiles . Nitrogen forms five oxides: nitrous oxide (N2O), nitric oxide (NO), dinitrogen trioxide (N2O3), nitrogen dioxide (NO2), and dinitrogen pentoxide (N2O5). . . Another metallurgical application of oxygen is in torches used for welding and cutting. Inorganic materials also react slowly with oxygen. The chemical industry uses vast amounts of oxygen every year in a variety of chemical synthesis (formation) reactions. Inhaled oxygen passes through the sac wall to directly enter the cardiovascular system, and waste carbon dioxide passes out into the lung. Jump to navigation Jump to search. Oxygen concentrator definition: An oxygen concentrator is a type of medical device used for delivering oxygen to individuals with breathing-related disorders. Priestley even tried breathing the new gas he had produced. The first use of liquid rocket propellants came in 1923 when Robert Goddard of the United States developed a rocket engine using gasoline as the fuel and liquid oxygen as the oxidizer. These particles stick in the atoms and make them radioactive. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list. When wood burned, for example, chemists said that phlogiston escaped from the wood to the air. Look for them in the pocket areas downstream from rapids. World of Sports Science. Its abundance is estimated at about 45 percent in the earth. Its most common and best known compound is probably water. Oxygen occurs in all kinds of minerals. That chlorine atom then reacts with ozone molecules, converting them into diatomic oxygen molecules. As a result, their output is consistent in quality. Oxygen and acetylene are combusted together to provide the very high te… 6 The liquid oxygen mixture, called crude liquid oxygen, is drawn out of the bottom of the lower fractionating column and is cooled further in the subcooler. As the crude liquid oxygen works its way down the column, most of the remaining nitrogen and argon separate, leaving 99.5% pure oxygen at the bottom of the column. The energy is used to lift the rocket into space. 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. Chemistry: Foundations and Applications. ." COLIN BLAKEMORE and SHELIA JENNETT "oxygen Suppose liquid air in a container warms up slowly. All acids do not contain oxygen, although some do. It has a natural abundance of 0.2 percent. In the upper part of the stratosphere, however, solar energy causes the breakdown of the diatomic form into the monatomic form, which may then recombine with diatomic molecules to form ozone. Nearly all of the oxygen found on Earth today is produced by biological activity. Thousands of oxygen compounds have important commercial uses. Perhaps the most important of all oxides is water, by far the most abundant compound on the planet. Oxygen also is a part of most organic molecules in the body, the building blocks for all living things. oxygen Insider Exclusive! Under most circumstances in nature, the diatomic form of oxygen predominates. ." ." Also, the combustion of coal, oil, and natural gas often releases sulfur dioxide to the atmosphere. https://www.encyclopedia.com/science/encyclopedias-almanacs-transcripts-and-maps/oxygen-0, "Oxygen Encyclopedia.com. It is then cooled and allowed to expand to nearly atmospheric pressure. Chemistry: Foundations and Applications. Lavoisier showed that this idea was incorrect. They are used in steel making and in the manufacture of synthetic chemicals. Oxygen is a non-metallic element of atomic number 8. Oxygen is made from liquid air. So, they say, it contains both carbon dioxide and oxygen? As Markarian is a starburst galaxy, undergoing furious star formation, this could be possible. It tends to break down and form dioxygen: Ozone does occur in fairly large amounts under special conditions. For example, the oxidation reaction between oxygen and sodium produces sodium oxide. The incoming air stream is cooled, while the oxygen and nitrogen are warmed. The uses to which oxygen is put can be classified into four major categories: metallurgy, rocketry, chemical synthesis, and medicine. Ozone —An allotrope of oxygen that consists of three atoms per molecule. This process produces carbon dioxide and water vapor, which are then captured and removed. Deep-sea divers also carry with them or have pumped to them supplies of air that are enriched with oxygen. Yet, some early scholars believed otherwise. He accused Lavoisier of plotting against the revolution. https://www.encyclopedia.com/sports/sports-fitness-recreation-and-leisure-magazines/oxygen, "Oxygen The liquid air is then allowed to evaporate. are called Type I and range from A, which is 99.0% pure, to F, which is 99.995% pure. Oxygen is necessary for the survival of all animal life on Earth. One of the most important of these is the cracking of hydrocarbons by oxygen. However, its liquid and solid state are blue. Oxygen forms in the hearts of stars, with the fusion of a carbon-12 nucleus and a helium-4 nucleus (also known as an alpha particle). Therefore, the new element was responsible for "forming acids." In some cases, the oxygen may also be passed over a catalyst to oxidize any hydrocarbons. Ordinary oxygen gas (O2) exists as diatomic molecules. Under most circumstances, heating a hydrocarbon with oxygen results in combustion, with carbon dioxide and water as the main products. The importance of oxygen to an athlete is most obvious in the healthy function of the respiratory system, without which competitive athletics would be impossible. Sodium carbonate, or soda, soda ash, or sal soda (Na2CO3), is an example. While the body can produce energy without the presence of oxygen, through its two anaerobic systems, for limited periods of time, ultimately the aerobic system will be required. In many instances, oxygen is manufactured at the location where it will be used. The Gale Encyclopedia of Science. Some common instances in which oxygen therapy is used include surgical procedures, following heart attacks, and during infectious diseases. Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA). 22 Dec. 2020 .
