What kind of gas is nitrogen, is it flammable and explosive?

Nitrogen is a colorless and odorless gas, and nitrogen is generally denser than air.

Small. Nitrogen is one of the main components of air.

Nitrogen is non-flammable and explosive. Chemical properties of nitrogen.

It is not active 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.

It is used to make new substances that are useful to human beings.

at standard atmospheric pressure.

, when nitrogen is cooled to, it becomes a colorless liquid, and when it is cooled to, liquid nitrogen.

Turns into a snow-like solid.

Extended Materials. Due to the chemical inertness of nitrogen, it is often used as a shielding gas, such as: melons and fruits, food, light bulb filling 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 cryogen 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.

Nitrogen is a major ingredient in the air, accounting for 78% of the volume of air in the air, the chemical properties are relatively stable, not easy to react with other substances, and it is not flammable, so it is not easy

1. Nitrogen is not a flammable and explosive gas, and it does not burn and does not support combustion.

2. "Nitrogen acceleration" used in racing refers to nitrous oxide.

4. Nitrogen acceleration cannot be used for a long time.

Carbon monoxide and acetylene are both flammable and explosive gases.

Nitrogen is very stable. Won't burn.

Nitrogen is a colorless, odorless, inert gasInsoluble in water. Nitrogen is a colorless and odorless gas, and nitrogen is generally less dense than air. Nitrogen is one of the main components of air.

Nitrogen is non-flammable and explosive. Nitrogen is chemically 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.

At standard atmospheric pressure, nitrogen becomes a colorless liquid when cooled to a point and liquid nitrogen becomes a snow-like solid when cooled to a point where it is cooled.

Flammable and explosive gases include hydrocarbons, such as hydrogen, carbon monoxide, methane, propane, ethylene, ethane, acetylene, etc., as well as hydrogen sulfide, natural gas, etc., flammable and explosive gases refer to any gases that can be ignited when exposed to fire, heat or contact with oxidants.

Common flammable and explosive gases include hydrogen, carbon monoxide, methane, propane, ethylene, ethane, acetylene and other hydrocarbons, as well as hydrogen sulfide.

Flammable and explosive gases are generally not accessible to us ordinary people, and liquefied gas is easier to see.

Nitrogen is non-flammable.

Nitrogen is an elemental element formed by the element nitrogen, with the chemical formula N. It is a colorless and odorless inert gas at room temperature and pressure, which can only react with hydrogen to form ammonia under high temperature and high pressure and catalyst conditions, and can be combined with oxygen to form nitric oxide under the condition of discharge; Even reactive metals such as Ca, Mg, Sr, and Ba can only react with them when heated.

This high chemical stability of nitrogen is related to its molecular structure, 2 n atoms combine with three bonds to form a nitrogen molecule, containing 1 bond and 2 bonds, because in the chemical reaction it is the bond that is attacked first, and in the n molecule the energy level of the bond is lower than the bond, and it is difficult to open the bond, thus making it difficult for n to participate in the chemical reaction.

Applications: The chemical properties of nitrogen are very stable and generally do not react with other substances. This inert quality makes it widely used in many anaerobic environments, such as the use of nitrogen to replace the air in the specific Rong Jinmin device, which plays the role of isolation, flame retardant, anti-explosion and anti-corrosion, and this technology is used in industrial and civil applications such as light hydrocarbon plant maintenance, LPG engineering, gas pipeline and liquefied gas pipeline network purging.

Nitrogen can also be used as a covering gas in the packaging of processed food and pharmaceuticals, to seal cables, ** wires, and to pressurize inflatable rubber tires. As a preservative, nitrogen is also often substituted downhole to slow down corrosion caused by string contact with formation fluids. <>

Liquid nitrogen is not flammable or explosive, it is inert, colorless, odorless, non-corrosive, non-flammable, and the temperature is extremely low.

Nitrogen is inactive and does not support combustion. Frostbite is caused by endothermic contact with a large amount of vaporization. Nitrogen makes up 78% of the air.

At atmospheric pressure, the liquid nitrogen temperature is 196; 1 cubic meter of liquid nitrogen can expand to 696 cubic meters of pure gaseous nitrogen at 21°C.

Liquid nitrogen is a colorless, odorless, and low-temperature liquid and gas under high pressure. Liquid nitrogen is the liquid form of nitrogen formed at low temperatures. The boiling point of nitrogen is -196°C, and liquid nitrogen will be formed if the temperature is below this at normal atmospheric pressure; If pressurized, liquid nitrogen can be obtained at higher temperatures.

Nitrogen is an inert gas.

Nitrogen is an elemental element formed by the element nitrogen, with the chemical formula N. It is a colorless and odorless inert gas at room temperature and pressure, which can only react with hydrogen to form ammonia under high temperature and high pressure and catalyst conditions, and can be combined with oxygen to form a section of lead nitric oxide under the condition of discharge; Even the genera Ca, Mg, Sr, and Ba can only react with them when heated.

Uses of Nitrogen:

1. Used as a shielding gas: The chemical properties of nitrogen are relatively stable at the temperature of ordinary oak gas, so it can be used as an inert gas and a shielding gas when welding metals.

2. Extend the life of the bulb: Nitrogen has the effect of anti-oxidation, and pouring it into the bulb can prevent the oxidation of tungsten filament, thereby prolonging the life of the bulb.

3. Used to store grain: nitrogen can be used to store grain, so as to avoid insects, mold, deterioration and other phenomena of grain.

4. Anti-oxidation: When producing glass, nitrogen can be used as a protective gas to avoid the phenomenon of tin bath oxidation.

5. Chemical fertilizer can be made: nitrogen can be made into chemical fertilizer, which is the raw material for the manufacture of chlorophyll and protein.

6. Used in medical and health care: nitrogen can also be used in medical and health care, and the gas has made an important contribution to medical and health care. <>

Nitrogen is a colorless, odorless, inert gas, insoluble in water, density standard condition) is less dense than air, nitrogen accounts for the total volume fraction of the atmosphere), is the main component of air.
