Yes
Nitrogen is a simple asphyxiant that is without other significant physiologic effects. Inhalation of nitrogen is dangerous only when it lowers the available oxygen in air to below life-sustaining levels
Do most organisms use nitrogen in the form of nitrogen gas?
No. They can not use nitrogen gas because the triple bonds of nitrogen can only be broken down for use in living things, plants, by the symbiotic bacteria in the root nodes. Then in other forms nitrogen is taken up into the plant and from there to other trophic levels.
What are two major ways in which nitrogen is fixed in ecosystems?
Nitrogen can be fixed in ecosystems through biological processes, like by nitrogen-fixing bacteria that convert atmospheric nitrogen into a usable form for plants. It can also be fixed through human activities, such as the use of nitrogen fertilizers in agriculture.
It took 300 thousand years after the big bang for the Universe to cool enough to create atoms; hydrogen and helium formed first. Nitrogen was formed in the stars through the process of nucleosynthesis. When a star's helium mass becomes great enough to reach the necessary pressure and temperature, helium begins to fuse into still heavier elements, including nitrogen.
What is the address for nitrogen?
Its address is 15th (V-A) group and 2nd period of periodic table of elements.
What is the difference between invivo and invitro nitrogen fixing?
When something is done invivo it is happening in a living plant, animal or bacteria.
When something is invitro it is done in the lab, in a petri dish of other artificial and controlled setting.
The use by beneficial soil microorganisms for their own benefit of nitrogen from large particle soil amendments is 'nitrogen drawdown'. Soil amendments are below ground conditioners that are either organic or mineral in their makeup. A popular form are wood chips.
Unfortunately, wood chips are so large that they may open up and thereby dry the very soil for which they're supposed to improve movement of air and moisture. They also attract beneficial decomposers. The problem lies in the strong attraction that the microorganisms feel towards the nitrogen in the chips.
Breakdown of the chips is supposed to release nitrogen and other nutrients into the soil. Unfortunately, the microorganisms may feed so much on the nitrogen that the soil becomes nitrogen deficient. Plants indicate the nitrogen deficient nature of such soil by turning yellow. The solution is nitrogen fertilizer treatments until the wood chips are broken down.
a molecule that carries Nitrogen and can Donate the Nitrogen towards building of other molecules like proteins or DNA. An important Nitrogen Shuttle is Glutamine. It can produce Ammonium, be a source of energy and have other functions too.
How do plants transfer nitrogen in the nitrogen cycle?
Plants mainly obtain nitrogen in the form of nitrates from the soil through their roots. This nitrogen is then used by plants to build proteins and other essential molecules. When plants die or shed leaves, nitrogen is returned to the soil through decomposition, where it can be taken up by other plants.
Nitrogen-fixing bacteria get nitrogen from?
Nitrogen-fixing bacteria get nitrogen from the atmosphere, specifically from nitrogen gas (N2). They convert this nitrogen gas into a form that plants can use, such as ammonia or nitrate, through a process called nitrogen fixation.
What elements does nitrogen have?
Nitrogen has the chemical symbol N and atomic number 7. It is a non-metal element on the periodic table. Its most common form is diatomic nitrogen gas (N2), which makes up about 78% of Earth's atmosphere.
Can you suffocate from nitrogen?
Yes, high concentrations of nitrogen can displace oxygen in the air, leading to oxygen deprivation and suffocation, a condition known as nitrogen asphyxiation. This is more likely in confined spaces with poor ventilation.
The person is in negative nitrogen balance, as they ingested less nitrogen (16g) than they lost (19g), meaning their body is breaking down more protein than it is building up. This can indicate a potential loss of lean body mass.
Does nitrogen gas consist of a molecule of two nitrogen atoms?
Yes. Nitrogen gas has the formula N2. A molecule of nitrogen gas consists of two atoms of nitrogen covalently bonded.
What is the balanced equation for nitrogen plus hydrogen -- nitrogen trihydride?
The compound which you call nitrogen trihydride is much better known as ammonia, and the formula is NH3.
Nitrogen-fixing bacteria in soil turns nitrogen gas into?
they turn the nitogen gas into the nitrates and nitrites essential for the soil
Number of nitrogen atoms in 1 mole nitrogen dioxide?
Number of nitrogen atoms in 1 mole nitrogen dioxide?
Nitrogen dioxide has 1 N atom and 2 O atoms.
One mole of nitrogen dioxide has 1 mole of N atoms
No, nitrogen is not a solvent. Nitrogen is a colorless, odorless, and inert gas that is commonly found in the atmosphere. It is not typically used as a solvent in chemical reactions or processes.
Using ordinary air between the panes of double-pane windows can lead to condensation forming inside the window due to the presence of moisture in the air. This condensation can reduce the insulating effectiveness of the window and cause visibility issues. Nitrogen gas or very dry air is used to prevent condensation and maintain the insulating properties of the window.
Well, they use it in the sense that it's about 80% of the air they're conditioning, but it's not used specifically in the operation of the air conditioner itself. One of the first refrigerants used in early (industrial) air conditioners was ammonia, a nitrogen compound, but as far as I know nitrogen itself has never been used.
How do animals and plants get nitrogen from the nitrogen cycle?
They use the nitrogen in the food they eat to form their bodies, particularly proteins. They throw out excess nitrogen with the help of excretion, and their bodies are decomposed after death into various forms of nitrogen, too.
What is the diffrence between fixed nitrogen and free nitrogen?
OK well free nitrogen is fixed by bacteria that live in the soil. some bacteria live in nodules, or bumps , on certain plant roots. the bacteria get food from the plants, and plants absorb fixed nitrogen from the bacteria. animals get nitrogen by eating plants or by eating prey that have eaten plants.
fixed nitrogen may enter the soil in other ways too. a small amount of free nitrogen in the air by lighting. it is carried to the ground by rainfall. fixed nitrogen also enters the soil because of decomposers. decomposers break down dead organisms, and fixed nitrogen is released in the soil. the fixed nitrogen can be absorbed by plant roots.
How to Convert Liquid nitrogen to nitrogen Gas?
This may not be as spectacular as you migh imagine. If one litre of liquid nitrogen turned to gas, then it would simply be no longer the liquid form of nitrogen, but the gas form of it. This starts to happen immediately: its te smoke like stuff coming of the liquid nitrogen. Nitrogen in its gas form is a normal part of our atmosphere, we need it to breathe, so one litre of LIQUID nitrogen turning to GAS nitrogen will not do anything cool., You need to put something in the liquid nitrogen, and as nitrogen can only be liquid at a very low temperature, what ever you put in it, will freeze and if you hit it it will break. Dont get any on you: it wil freeze your flesh off
Yes, nitrogen is valuable as it is an essential element for all living organisms. It is a crucial component of proteins, nucleic acids, and other biomolecules. Additionally, nitrogen is used in the production of fertilizers to enhance crop growth and improve agricultural productivity.
