Yes. Technically, every element exists somewhere in outer space, though usually in incredibly small densities.
Space is thought as a vacuum but it does contain small amounts of gases. It is mainly comprised of hydrogen plasma particles. There is no nitrogen that has been found in open space yet.
Nitrogen displaces oxygen in the confined space, leading to a lack of oxygen in the bloodstream when breathed in by the person. This can rapidly lead to unconsciousness and ultimately death due to oxygen deprivation. Nitrogen itself is not toxic, but the lack of oxygen is what causes harm.
In general ... No. Gaseous Nitrogen has little or no place in an near future space settlements. It is not needed in current space ventures - except to reduce oxygen partial pressure near the Earth's surface.
The atmosphere of the space station is the same as on Earth, 78% nitrogen and 21% oxygen.
You are describing Neptune, the eighth planet from the sun in our solar system. Neptune's atmosphere is rich in nitrogen, which can form clouds of frozen nitrogen that are visible in its blue color. It's moon Triton has geysers that shoot gaseous nitrogen into space.
Like all gasses, nitrogen takes up space, so when nitrogen is put into a given area it pushed other gasses, including oxygen, out of the way.
Oxygen and nitrogen are elements, not matter in themselves. Matter refers to anything that has mass and takes up space, which includes elements like oxygen and nitrogen, as well as compounds and mixtures.
you use 100000 tonnes of nitrogen gas and ignite it and then off you go!
The nitrogen used to protect steel from water is called nitrogen blanketing. This process involves filling the space above the liquid with nitrogen gas to prevent moisture from coming into contact with the steel. This helps to prevent corrosion and rusting of the steel surface.
Liquid nitrogen and oxygen are transported as liquids into space because they have a higher density in liquid form, allowing more of these gases to be packed into the spacecraft's tanks. This is important for providing sufficient breathable air and cooling systems for astronauts during space missions. Additionally, liquid nitrogen and oxygen have to be kept at very low temperatures for storage, and transporting them as liquids helps maintain those temperatures more effectively.
The answer is 2,68 moles.
There is no air in space. If you mean what is the atmosphere in the Space Station, it is essentially an ordinary Earth air mixture of nitrogen and oxygen.
