What is Oxygen Gas?
There is no doubt that none of the chemical elements have played a more important role than Oxygen in the development of chemistry. This life-giving gas was able to make such a huge breakthrough in chemistry in the late eighteenth century that it had never been possible before.
Oxygen can be introduced as the most abundant element in the Earth's crust. This element, which takes the form of Diatomic molecules in its most stable state at standard temperature and pressure, is the Oxygen gas or the most vital element for human beings. After the discovery of oxygen, the amount of Oxygen present on Earth was generally estimated at 46%, and its amount in the air around us is 20%. The percentage of Oxygen in the oceans is estimated at 87% due to the partnership of Oxygen in the formation of H2O molecules. In the following text, we will discuss how to discover this element.
Molecular Oxygen produces energy in the process of burning, breathing aerobic cells. Many organic molecules in living organisms, such as proteins, nucleic acids, carbohydrates, fats, as well as a wide range of mineral compounds in animal shells, teeth, and bones, have Oxygen atoms in themselves. Most living organisms are made up of oxygen, because the animal body is mostly consist of water, and Oxygen is the main building block of water.
Oxygen in the Earth's atmosphere is continuously supplied by the process of photosynthesis, the process by which sunlight converts water and carbon dioxide into oxygen. Chemically, Oxygen is very active and therefore cannot remain free and atomic in fresh air.
In addition to molecular oxygen, Oxygen has other deformations, which include ozone. The ozone molecule is able to absorb the ultraviolet light emitted by the sun, and as a result, the ozone layer covering the earth protects life on Earth from destructive ultraviolet rays. However, ozone produced near the Earth's surface is a byproduct of the reaction of smog and is therefore considered a polluting agent.
What are the uses of oxygen gas?
Oxygen is commonly used in the production of steel, plastics, textiles, Oxygen cutting of steel, rocket propulsion, Oxygen therapy and life support systems in airplane, submarines, space flights and diving. Multiple applications of Oxygen gas as an oxidizer is of high importance. The electronegativity of Oxygen is very high, which makes it susceptible to reaction. Only fluorine has a higher electronegativity than oxygen. Due to its oxidizing properties, Oxygen is used as fuel in missiles. The discovery of Oxygen in the air and its extraction from the air meets the practical needs. Air-extracted Oxygen is used in a mixture with low-density gas such as helium as a breathing mixture for respiratory patients as well as divers. Oxygen is also used in welding, steel production and methanol production.
Oxygen gas is one of the most widely used medical gas in the hospital and in order to survive, in most parts of the hospital, including inpatient rooms, operating room, postoperative care room (recovery), cardiac care unit, neonatal ward, Maternity and emergency department is used. This gas is very dangerous in terms of explosion and combustion and its reaction with hydrogen is very exothermic.
In cells, Oxygen is needed for aerobic respiration, which allows energy to be extracted from the food eaten. So supplemental Oxygen at home and in hospitals is vital for people with respiratory disorders such as emphysema.
Excess Oxygen is needed for surgical patients who are deliberately used for medical procedures, in which case the "heart and lungs" continue their vital function.
Oxygen can be used as a disinfectant to kill some anaerobic bacteria that are killed by adequate gas exposure.
Oxygen is required for the reaction that converts carbon to carbon dioxide gas in steel works, which takes place at high temperatures in a high blast furnace.
The carbon dioxide produced reduces iron oxides to pure iron compounds. Oxygen is used in applications involving metal and requiring high temperatures, such as welding torches.
