What is Oxygen

The oxygen is a gaseous chemical elementcolorless, odorless and tasteless, abundant in the earth’s crust, in the atmosphere and in the oceans, which is essential for life.

In the periodic tableis represented by the symbol EITHER and is part of vla group, of the family of amphigens or chalcogens. Their atomic number is 8 and his atomic mass16.

As a gas, it is heavier than air.and constitutes one fifth of it in its molecular form EITHER2. Also is part of the waterof oxides, of almost all acids and organic substances, and It is present in our body and in all living beings.. Result essential for breathing of animal and plant species (photosynthesis), and in the generation of carbon dioxide (CO2). It is very reactive, and activates the combustion processes. Gathered in a composition of three atoms (O3) is known as ozonethe gas that constitutes the ozonosphere, vital atmospheric layer to protect us from ultraviolet radiation from the Sun.

The expression is also used “give oxygen” to refer to the need to spice up or invigorate a situation. Also, the expression “oxygen balloon” is used in an equivalent sense: “The point rescued as a visitor supposes a oxygen balloon for the team.”

uses of oxygen

The oxygen It is widely used by humans: industrially it is used for the production of steel, welding and cutting of iron materials; to obtain a wide variety of substances, important in the manufacture of textiles and plastics; for the purification of waste water and the manufacture of explosives. In its liquid stateis used as fuel in rockets, as well as for the generation of artificial air in aircraft, submarines, spacecraft and scuba diving.

Dissolved oxygen

What dissolved oxygen The amount of dissolved oxygen in the water is known. It is essential for the respiration of aquatic animal and plant speciesIn addition, its measurement is used to determine the levels of Water contamination and therefore the underwater living conditions.

The oxygen dissolves in water thanks to oxygenation processes such as photosynthesis of aquatic plants, or those derived from the movement of water, such as the flow of a river between rocks or the waves produced by the wind. The factors Influencing the concentration of dissolved oxygen in water are atmospheric pressure, salinity levels in water, temperature, stream flow, presence of aquatic plants, decomposing organic matter, and human activity.

The word is made up of the Greek words ὀξύς (óxys), which means ‘acid’, and γένος (génos), ‘origin’, ‘lineage’, ‘clan’. Formerly, it was believed that the oxygen it was necessary to produce acid, hence its name, which would translate literally: “that produces acid”.
