  2. Chemically inert - Wikipedia

    Nevertheless, nitrogen gas does react with the alkali metal lithium to form compound lithium nitride (Li 3 N), even under ordinary conditions. Under high pressures and temperatures and with the right catalysts, nitrogen becomes more reactive; the Haber process uses such conditions to produce ammonia from atmospheric nitrogen. [3]

  3. Nitrogen - Wikipedia

    en.wikipedia.org/wiki/Nitrogen

    Because the liquid-to-gas expansion ratio of nitrogen is 1:694 at 20 °C, a tremendous amount of force can be generated if liquid nitrogen is rapidly vaporised in an enclosed space. In an incident on January 12, 2006, at Texas A&M University , the pressure-relief devices of a tank of liquid nitrogen were malfunctioning and later sealed.

  4. Reactive nitrogen - Wikipedia

    en.wikipedia.org/wiki/Reactive_nitrogen

    Reactive nitrogen ("Nr"), also known as fixed nitrogen [1], refers to all forms of nitrogen present in the environment except for molecular nitrogen (N 2 ). [ 2 ] While nitrogen is an essential element for life on Earth, molecular nitrogen is comparatively unreactive, and must be converted to other chemical forms via nitrogen fixation before it ...

  5. Inert gas - Wikipedia

    en.wikipedia.org/wiki/Inert_gas

    The term inert gas is context-dependent because several of the inert gases, including nitrogen and carbon dioxide, can be made to react under certain conditions. [1] [2] Purified argon gas is the most commonly used inert gas due to its high natural abundance (78.3% N 2, 1% Ar in air) [3] and low relative cost.

  6. Monatomic gas - Wikipedia

    en.wikipedia.org/wiki/Monatomic_gas

    It is usually applied to gases: a monatomic gas is a gas in which atoms are not bound to each other. Examples at standard conditions of temperature and pressure include all the noble gases ( helium , neon , argon , krypton , xenon , and radon ), though all chemical elements will be monatomic in the gas phase at sufficiently high temperature (or ...

    Fruitcake. Step one of a fruitcake is soaking pounds of dried fruit until it's plump and filled with bourbon. That takes up to 12 hours. Step two is simple: making and baking the loaves.

    Liquid nitrogen. Nitrogen is a colourless, odourless, and relatively inert diatomic gas with a density of 1.251 × 10 −3 g/cm 3 (marginally heavier than air). It condenses to a colourless liquid at −195.795 °C and freezes into an ice- or snow-like solid at −210.00 °C.
