Yes. This is due to the molecular structure of nitrogen, there are three pairs of electrons between two nitrogen atoms (commonly known as covalent triple bonds), the bond is very strong, and the bond energy is particularly large, resulting in the nitrogen molecule is particularly stable and often acts as a protective gas.
However, under harsher conditions, nitrogen can also react chemically with other substances.
For example, under discharge conditions, nitrogen reacts with oxygen to form nitrogen oxides;
It is combined with hydrogen under the conditions of high temperature, high pressure and catalyst existence;
reacts with magnesium metal at high temperatures, and so on.

Be. Determine the molecular structure of nitrogen, two nitrogen atoms, on electrons (covalently commonly said triple bonds), plus a very solid, bond can be extraordinarily large, resulting in a particularly stable nitrogen molecule, often as a shielding gas.
But under more demanding conditions, nitrogen reacts chemically with other substances.
For example, under the condition of discharge, nitrogen and oxygen react to form nitrogen oxides;
Under the conditions of high temperature, high pressure, chemical compounds carried out in the presence of catalysts, with hydrogen; > reaction with magnesium metal at high temperatures, etc.
-
Yes, because the triple bond of N2 is very strong and does not break easily.
-
Yes, nitrogen and other gases such as hydrogen need to be reacted with a catalyst at high temperature and pressure.
-
Yes, a lot of our food packaging is flushed with nitrogen.
-
Yes, otherwise, how could there be so much nitrogen in the air?

Substances that react with nitrogen:
1.Oxidation state of nitrogen: elemental spike nitrogen is not active, only under the conditions of high temperature and high pressure and the presence of catalysts, nitrogen can react with hydrogen to form ammonia; Under discharge conditions, nitrogen can be combined with oxygen to form nitric oxide.
2.Nitrogen is a substance with a small separation potential from the electric cready, and its nitride has a high lattice energy, and the metal can form ionic nitrides. For example:
Nitrogen and lithium metal can directly react at room temperature to form lithium nitride; Nitrogen reacts with alkaline earth metals magnesium, calcium, and barium at a red-hot temperature; Nitrogen reacts with boron and aluminum at white-hot temperatures.
3.The elemental elements of nitrogen and silicon and other elements are generally released at temperatures higher than 1473K.

Summary. Dear, I'm glad to answer for you, nitrogen production through chemical reaction can be oh, there are two ways to produce nitrogen, namely: 1. Nitrogen production on an industrial scale, that is, cryogenic air separation nitrogen production, pressure swing adsorption nitrogen production and membrane separation nitrogen production, using the different boiling points of each air, using the liquid air separation method, the oxygen and nitrogen are separated, and the bottle containing nitrogen is painted into heise, and the nitrogen can be filled in;
Can nitrogen be produced by chemical reaction.

2. In the laboratory, nitrogen is generated, and the solution of heated ammonium nitrite is used to decompose to produce nitrogen, and sodium nitrite interacts with the saturated solution of ammonium chloride to produce nitrogen, or ammonia is reacted with red-hot copper oxide and ammonia water with bromide, and ammonium dichromate is heated and decomposed, and sodium azide is heated to decompose it, and nitrogen can be produced.

The explanation of the people upstairs is wrong, the nitrogen and oxygen in the air will react chemically in the case of discharge, and the nitric oxide N2+O2=2NO (the condition is discharge) will occur, and it is the only direct product of the reaction, although there are many nitrogen oxides. Other oxides of nitrogen are obtained by other means.
You've heard the saying "thunderstorm fertilizes crops", which indicates that nitrogen and oxygen react chemically when discharged.
Because the nitrogen and oxygen in the air will react chemically when discharged to produce nitric oxide.
Nitric oxide is then oxidized by oxygen in the air to nitrogen dioxide.
Nitrogen dioxide reacts with water to form nitric acid, which eventually falls into the ground and reacts with minerals to form nitrate! Namely: nitrogenous fertilizers.
There is also the nitrogen oxide in the exhaust of the car is also the first to react with nitrogen and oxygen in the case of spark plug dischargeN2+O2=2NO, and then react with oxygen to convert into other forms of air pollutants.

N2+O2 = (discharge) 2NO, 2NO+O2=2NO2, 3NO2+H2O=2HNO3+ NO.
The process of converting molecular nitrogen into ammonia by nitrogen-fixing organisms (such as various nitrogen-fixing bacteria) nitrogenase in nature.
Biological nitrogen fixation refers to the process by which nitrogen-fixing microorganisms reduce atmospheric nitrogen to ammonia.
The content of nitrogen fixed by nitrogen-fixing microorganisms is far from being compared with artificial nitrogen fixation and high-energy nitrogen fixation, and it can be said that nitrogen fixation in nature is mainly dependent on biological nitrogen fixation. Biological nitrogen fixation plays an important role in the nitrogen cycle in nature.
The rhizobia of leguminous plants, as well as the nitrogen-fixing spirobacteria in the roots of pastures and other grasses, and some prokaryotic lower plants, nitrogen-fixing cyanobacteria, and autogenous nitrogen-fixing bacteria, all contain nitrogenases, which have nitrogen-fixing effects. This category is biological nitrogen fixation that is naturally nitrogen-fixing.

From the oxidation state of nitrogen - Gibbs free energy diagram and the structure of N2 molecule, it can be seen that elemental N2 is inactive, and nitrogen can react with hydrogen to form ammonia only under the conditions of high temperature and high pressure and the presence of catalyst
Under discharge conditions, nitrogen can be combined with oxygen to form nitric oxide.
In countries where hydropower is highly developed, this reaction has been used to stimulate the production of nitric acid.
N2 has a small ionization potential with nitride, and its nitride has a high lattice energy, and the metal can form an ionic nitride ruler mountain substance. For example:
N2 with lithium metal.
At room temperature, it can directly react to the bright dilemma:
6 li + n2===2 li3n
N2 with alkaline earth metal.
mg, ca, sr, ba act at red-hot temperatures:
3 ca + n2===ca3n2
N2 reacts with boron and aluminium at white-hot temperatures
2 b + n2 ===2 bn (macromolecular compound) N2 reacts with silicon and other elements at temperatures higher than 1473 K.

Nitrogen is chemically stable and inactive, and it is difficult to react with other substances at room temperature, so it is often used to make preservatives. However, under high temperature and high energy conditions, it can undergo chemical changes with certain substances and be used to make new substances useful to human beings. Nitrogen is mainly used in the synthesis of ammonia and is often used as a shielding gas due to its chemically inert nature, such as:
Fruits, food, bulbs fill gas. In order to prevent some objects from being oxidized by oxygen when exposed to air, fill the granary with nitrogen, which can make the grain not rotten and germinate, and be stored for a long time. Liquid nitrogen can also be used as a deep freezer.
It is also often used as a cryogenic agent in the hospital for surgery to remove spots, bags, beans, etc., that is, to freeze off spots, bags, beans, etc., but it is prone to scarring, so it is not recommended. High-purity nitrogen is used as a carrier gas for instruments such as chromatographs. It is used as a bright annealing shielding gas for copper tubes.
Together with high-purity helium and high-purity carbon dioxide, it is used as a laser gas for laser cutting machines. Nitrogen is also used as a protective gas for food preservation. In the chemical industry, nitrogen is mainly used as a shielding gas, a displacement gas, a washing gas, and a safety guarantee gas.
It is used as a shielding gas for aluminum products, aluminum profile processing, aluminum thin rolling, etc. It is used as a shielding gas for reflow soldering and wave soldering to improve the quality of soldering. It is used as a shielding gas in the production process of float glass to prevent oxidation of the tin bath.

Theoretically, there will be no electric shock. Because the condition of electric shock is that there is an electric current passing through the human body.
