Is liquid nitrogen an example of Bose Einstein condensates?
As of 2010, the Bose-Einstein condensate state of matter has only been achieved in temperatures of 10-7 K in many alkali and alkaline earth metals' isotopes.
They include: 7Li, 23Na, 39K, 41K, 85Rb, 87Rb, 133Cs, 52Cr, 40Ca, 84Sr, 86Sr, 88Sr, and 174Yb
What other names does nitrogen go by?
It has other names in other languages (for example, the German Stickstoff), but they all just mean "nitrogen". There really aren't any synonyms for it in English.
At one time air from which oxygen had been removed (leaving mainly nitrogen, usually with some carbon dioxide) was called "phlogisticated air", but no one nowadays uses that terminology.
Why are the elements carbonhydrogenand nitrogen important to life on earth?
because these 4 elements that are listed are the most common elements on planet earth. most percentage of the eart is made of there 4 elements but not all some elments like iron are also there but a extremly small percentage
What is the mass of nitrogen in grams?
One mole of atoms of an element is equal to the atomic mass of that element expressed in grams.
Nitrogen-14
so one mole of nitrogen weighs 14 g
molecules of nitrogen bounce off from each other and don't stick together
What is the correct Lewis structure for an Nitrogen atom?
Two electrons in the first shell (closest to the nucleus), then five on the next shell out, usually shown as a pair and 3 singles.
What if a plant has not have enough nitrogen?
nitrogen helps to make protein, which is important for growth.
if a plant won't get nitrogen, it's growth will be slow and it will have small pale leaves :)
Why is nitrogen is the largest percentage than oxygen?
Sodium Atom has a larger atomic radius than chlorine, because as we go across the period the nuclear charge (charge on the atom) increases, also outermost electrons occupy the same principle energy level as we go across the period(3 sub energy level) so the electrons in chlorine are held more closely and tightly together than that of sodium....so sodium has a larger atomic radius
How is organic nitrogen produced?
Because nitrogen is usually very unreactive, it is only commonly found in internal combustion engines (car engines) where the temperature is high enough to make the nitrogen react.
How do nitrogen get into the soil?
Ammonia or nitrate is the type of nitrogen that plants tend to get through their roots.
Specifically, nitrogen is the most abundant element in the soil. But it may not be in a form that can be accessed by plants. Nitrogen that is in ionic forms as ammonia (NO4) and nitrate (NO3) will be taken in dissolved forms by plant roots.
How does nitrogen move from an abiotic element of the system to a biotic elemenr and back?
There are several paths.One of those is the Nitrogen Fixing Bacteria helps fix the nitrogen in the agricultural fields and passes that to plants.Plants when die release it again and goes somewhere else.The number of nitrogen atoms should remain the same unless it react with any other elements or compounds.
What converts organic nitrogen into atmospheric nitrogen?
Denitrifying bacteria play a key role in converting organic nitrogen compounds in the soil back into atmospheric nitrogen through a process called denitrification. This process helps to replenish the nitrogen cycle by releasing nitrogen gas back into the atmosphere.
Where can nitrogen be found or mined at?
Elemental Nitrogen may be conveniently obtained by cryogenic distillation from the atmosphere. The liquid form is widely used as a low temperature coolant. It is an important part of our diet, and is found in proteins. Nitrates are very useful chemicals, and until recently, were obtained from immense deposits of seabird droppings, sometimes called guano.
What role does nitrogen play in plant synthesis?
well i ma doing test corrections on that question now, so i can tell you that it is either proteins, gluclose, or waxes, but i think its either protiens or waxes. :)
The question is totally misguided. Nitrogen is the most abundant gas in the atmosphere, representing around 78%. Its crustal abundance is not quite that high because it is not a very reactive element.
Nitrogen compounds are found in foods, fertilizers, poisons, and explosives. Nitrogen gas is used as a blanketing medium during the production of electronic components. Nitrogen is also used in annealing stainless steels and other steel products. Liquid nitrogen is used as a refrigerant. Although nitrogen gas is fairly inert, soil bacteria can 'fix' nitrogen into a usable form, which plants and animals can then utilize. Nitrogen is a component of all proteins. Nitrogen is responsible for the orange-red, blue-green, blue-violet, and deep violet colors of the aurora
For a 1 mole sample of nitrogen, the density is 0.0022g/mL. P = 2 atm n = 1 mole T = 310K R = 0.0821 V = nRT/P = 12.73L = 12,730 mL Nitrogen = 28.02 g (Mass of one mole of Nitrogen gas i.e. N2) [2 x 14.01] d = 28.02g/12,730mL = 0.0022g/mL
Is neutral nitrogen monoxide diamagnetic or paramagnetic?
No. N2 is diamagnetic, there are no unpaired electrons.
What process is nitrogen returned to the atmosphere by bacteria?
The process is called denitrification.

What is lithium plus nitrogen?
Li3N; the lithium ion has a charge of +1 (Li+) while the nitride ion has a charge of -3 (N3-)
Where can you buy liquid nitrogen?
Liquid nitrogen is typically available for purchase from gas suppliers, welding supply stores, or industrial gas companies. However, it is important to adhere to proper safety protocols when handling and storing liquid nitrogen.
