Nitrogen nonmetal element N2 inert element Figure 1: Nitrogen is an inert gas; it does not react with other compounds because its triple bond is too strong to break NH3 What is Nitrogen's Symbol? What is nitrogen's symbol? Nitrogen is a nonmetal element with the chemical symbol N. The na...
Is nitrogen gas a metal/nonmetal, properties (atomic mass, melting point, boiling point, density, electron configuration), what is it used for, cost
Cryogenic liquids like oxygen, nitrogen, and argon are often used in industrial and medical applications. The electrical resistance of most metals decreases as temperature decreases. Certain metals lose all electrical resistance below some transition temperature and become superconductors. An electromagnet ...
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...
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...
just air or inert gas. With gas backing, inert or semi-active (Nitrogen + hydrogen, which is fairly active even in small quantities) gas is generally meant. Air = no backing, but I understand the premise. @ gtaw, Clearly you are correct. For that purpose I explicitly mentioned EN/ISO...
They spontaneously react with oxygen, water, halogens , phosphorus, sulfur, and other substances; lithium even reacts with nitrogen. Reactions with water can be violent, with the evolution of hydrogen gas and formation of strongly alkaline solutions. ...
Cyanide is a molecule that consists of one carbon atom triple-bonded to one nitrogen atom. The chemical formula for cyanide is CN–. It is most famous for its potential as a deadly poison to humans and other life forms. Even the ancient Egyptians documented what many believe to be cyanide...

For the year, nitrogen gross margin of $315.6 million almost matched the record $318.7 million of 2005, as excellent market conditions continued. Our Trinidad operation, which enjoys lower-cost, long-term natural gas contracts, contributed $48.1 million of gross margin for the quarter and $182.5...
