Learn what is nitrogen and see nitrogen's symbol. Understand what nitrogen fixation is and the formulas that represent it. See the importance of...
Oxygen gas is commercially extracted by fractional distillation of liquefied air[1]. It can also be obtained by passing dry air through zeolite, a microporous mineral that can absorbnitrogenbut leave oxygen[1]. Passing the air through a selectively permeable ceramic membrane can produce highly pure...
The remaining cooled gaseous portion is returned through the other side of the heat exchanger where it precools the incoming high-pressure air before returning to the compressor. The liquid portion is usually distilled to produce liquid oxygen, liquid nitrogen, and liquid argon. Other gases, such...

英文: Nitrogen: Gaseous chemical element, chemical symbol N, atomic number 7. A colourless, odourless, tasteless gas, it makes up 78% of Earth's atmosphere and is a constituent of all living matter. 中文: 氮:气态化学元素,化学符号N,原子序数7。无色、无臭、无味的气体,占地球大气的78%,也是...
Oxygen, a colorless, odorless, tasteless gas essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere. Oxygen forms
13. To ensure an inert furnace atmosphere, nitrogen gas flow was introduced into the 40 mm diameter quartz tube of length one metre which was placed into the furnace. The inlet and output of the quartz tube were connected to pyrex glass. The furnace was constructed by using fire brick ...
For this, the air sample was first liquefied and after that introduced to the process of boiling. The gases that were liberated during the process of boiling were captured. Three gases that were distinctly identified were oxygen, nitrogen, andargon. Krypton gas was also discovered at that time...
In 1894, Ramsay isolated all the components, including nitrogen,oxygen, andcarbondioxide from the air[4]. Nitrogen was removed from the gas by reacting it withmagnesium, resulting in solid magnesium nitride[1]. The gas that was left occupied 1/80th of the original volume and was chemically ...
