Is liquid nitrogen legal in america?
Yes, as in (most parts of) the whole world
Metal shrinking liquid nitrogen?
Liquid nitrogen can be used to shrink metal parts by rapidly cooling them, causing them to contract. When the metal is immersed in liquid nitrogen, its temperature drops significantly, resulting in a contraction of the metal due to thermal contraction. This process can be useful in manufacturing and repairing metal components that need precise fitting or tight tolerances.
Why does a flower become brittle and hard when submerged into liquid nitrogen?
When a flower is submerged into liquid nitrogen, the extreme cold causes the water inside the flower's cells to freeze rapidly. This rapid freezing creates ice crystals that disrupt the cell structure, making the flower brittle and hard when it thaws out.
Are VW cars dipped in wax?
Yes; the wax dip keeps the hidden parts from rusting.
What is 232?
2 parts nitrogen, 3 parts phosphate, 2 parts potash.
Nitrogen is released to the abiotic parts of the biosphere from the processes of death and?
Nitrogen is released to the abiotic parts of the biosphere through decomposition of organic matter and nitrogen-fixing bacteria in the soil. When organisms die, their nitrogen-containing molecules are broken down by decomposers, releasing nitrogen back into the environment. Additionally, nitrogen-fixing bacteria can convert atmospheric nitrogen into a form that plants can use, further cycling nitrogen through the ecosystem.
What is 232 fertilizer?
2 parts nitrogen, 3 parts phosphate, 2 parts potash.
What are the major parts in the nitrogen cycle?
The major parts of the nitrogen cycle include nitrogen fixation (conversion of atmospheric nitrogen into forms usable by plants), nitrification (conversion of ammonium into nitrites and nitrates by bacteria), denitrification (conversion of nitrates back into atmospheric nitrogen), and assimilation (incorporation of nitrogen into plant and animal tissues).
What is good for patchy grass?
Two parts hydrogen and one part oxygen. Mix together to form a liquid and treat areas daily.
Does your body need nitrogen?
yes. nitrogen is a main component in our DNAs and also in other parts of our body. the elements in variable proportion are found in our body parts.

How is nitrogen obtained?
Nitrogen is produced commercially almost exclusively from air, most commonly by the fractionaldistillation of liquid air. In this process, air is first cooled to a temperature below that of the boiling points of its major components, a temperature somewhat less than - 328°F (-200°C). The liquid air is then allowed to warm up, allowing the lower-boiling-point nitrogen to evaporate from the mixture first. Nitrogen gas escaping from the liquid air is then captured, cooled, and then liquefied once more.This process produces a high-quality product that generally contains less than 20 parts per million of oxygen. Both an "oxygen-free" form of nitrogen (containing less than two parts per million of oxygen) and an "ultra-pure" nitrogen (containing less than 10 parts per million of argon) are also available commercially.A number of methods are available for preparing nitrogen from its compounds in the laboratory on a small scale. For example, a hot aqueous solution of ammonium nitrite decomposes spontaneously to give elemental nitrogen and water. The heating of barium or sodium azide (NaN3 or Ba[N3]2) also yields free nitrogen. In another approach, passing ammonia gas over a hot metallic oxide will result in the formation of free nitrogen, the free metal, and water. Yet another route is the reaction between ammonia and bromine, resulting in the formation of nitrogen and ammonium bromide.Read more: http://science.jrank.org/pages/4683/Nitrogen-How-nitrogen-obtained.html#ixzz0SsRqYUZ9
