Yes it can be sold in canisters, if you mean solid yes again but at incredibly low temperatures, think about how cold liquid nitrogen is
NO
no
As with most gasses, nitrogen is usually sold in metal canisters with a valve at the top (like the kind you see people filling baloons with Helium from). Alternately, liquid nitrogen is available for sale and comes in a sealed canister.
Yes, liquid nitrogen exists. It is sold in strong, insulated containers and is used to instantly freeze biological specimens or tissue.
Liquid nitrogen is made by taking in air from the atmosphere and compressing and cooling it. Once it is cool enough, it forms a liquid. This liquid contains argon, oxygen and nitrogen. These elements are then separated and sold as a commodity. The temperature is the only difference.
KG is only used for liquified gas in cylinders such as propane which is sold by weight. Compressed gas and bulk liquid such as nitrogen is not sold by weight.
All soil contains nitrogen - it is a matter of how much. The relative amount of nitrogen in soil can be determined with as small soil sample and a reagent for nitrogen from a soil test kit (simple soil test kits are sold in every garden center). The results do not tell you the "amount" of nitrogen in the soil, only if there is enough for healthy plant growth, or if the amount of nitrogen is too poor for healthy plant growth
A nitrogen fertilizer is what is used to fertilize pecan trees (Carya illinoiensis).Specifically, ammonium nitrate is an effective, reasonably priced nitrogen fertilizer for pecan trees. It is sold in packages marked 33-0-0 for 33% weight of nitrogen and 0% each of phosphorus and potassium. Another effective, reasonably priced nitrogen fertilizer is ammonium sulfate (21-0-0), at 21% nitrogen.
Nitrogen is an inert gas. The oxygen in air - contributes to food going bad quickly, and also changes the flavour of food over time. Replacing the air inside food packaging with nitrogen- prolongs shelf life and flavour.
Sealing food packets with nitrogen helps to displace oxygen, which can cause food to spoil by promoting oxidation. Nitrogen is an inert gas that helps to preserve freshness, color, and flavor by creating a more stable atmosphere inside the packet. This process helps to extend the shelf life of the food product.
Nitrogen is a gaseous element, that is, what is in nitrogen is nitrogen.
Solid nitrogen is called "nitrogen ice" or "nitrogen snow".
