Oxygen

EASY Science F tenor Project for strain school..... - Oxygen, symbolisation O, colorless, odorless, tasteless, moderately magnetic burn outeous fixings. On earth, atomic number 8 is more immense than any otherwise element. Oxygen was discovered in 1774 by the British chemist Joseph Priestley and, independently, by the Swedish chemist Carl Wilhelm Scheele; it was shown to be an elemental gas by the French chemist Antoine Laurent Lavoisier in his classic experiments on combustion.         Large amounts of atomic number 8 are habituate in senior high school up-temperature welding torches, in which a compartmentalization of oxygen and a nonher gas produces a flame of oft higher(prenominal) temperature than is obtained by burning gases in direct. Oxygen is administered to patients whose breathing is disconcert and also to people in aircraft flying at high altitudes, where the poor oxygen concentration cannot support normal respiration. Oxygen-enriched ai r is used in open-hearth furnaces for steel manufacture.         Most of the oxygen produced in the United States is used to make a mixture of cytosine copy monoxide and hydrogen called synthesis gas, used for the synthesis of wood alcohol and ammonia. High-purity oxygen is used also in the metal-fabrication industries; in quartz glass clear piss it is of great importance as a propellant for channelise missiles and rockets2.         I suck up chosen the element Oxygen because without Oxygen, human beings would not be able to live.

Oxygen is in all probability the single to the hig hest degree important element in the popula! tion as we issue it. With out Oxygen we would not breath, have water, eat plants. Oxygens negatron configuration is 1S2 + 2S2 + 2P4, its electron dot symbol is: .          Gaseous oxygen can be condensed to a nauseated blue liquid that is strongly magnetic. Pale blue unbendable oxygen is produced by compressing the liquid. The atomic load of oxygen is 15.9994.Oxygen composes 21 portion by volume or 23.15 portion by weight of the atmosphere;...
