Nitrogen
Nitrogen (N) has the atomic number 7 on the periodic table and is mostly found in the colorless, gaseous form. Nitrogen is also the most abundant element on the planet Earth.
522 Questions
Why nitrogen does not support fire?
Nitrogen does not support fire because it is considered a non-flammable substance. Liquid nitrogen prevents fire from spreading because it inhibits fuel and oxygen from burning.
What is the conventional standard state of nitrogen?
Gaseous N2 molecules, because it exists in diatomic form at 1 atm of pressure and 25ºC
During one part of the nitrogen cycle nitrogen is removed from the air by mainly by nitrogen-fixing?
bacteria
Does Costco inflate your tires with nitrogen for free?
Yes, Costo does inflate the tires with nitrogen for free.
Which of these compounds are a source of nitrogen for animals?
The question refers to "these compounds". In such circumstances would it be too much to expect that you make sure that there is a list of compounds that "these" may refers to? I regret that we, at the Answers community, have not yet mastered the ability to read your mind!
Why does Nitrogen gas need to be converted into a different form?
Plants cannot use n as N2. So it has to be converted
Why is bacteria important to the nitrogen cycle?
bacteria in root fixes free nitrogen ito simple compounds
Which step in the nitrogen cycle is accelerated in the eutrophication process?
In eutrophication the nitrification step in the nitrogen cycle increases resulting in the over growth of food that plants can feed on. This can lead to a lower oxygen level causing the death of marine life.
What is necessary for nitrogen to combine with oxygen?
They reacting together to form nitrogen oxides. N2o is a example.
Nitrogen is the most common element in the air. Why do bacteria play a role in the nitrogen cycle?
Several bacteria can fix the nitrogen fom atmosphere.
2NF3 --> N2 + 3F2
What contains to bacteria convert nitrogen into?
the ammonia is converted by bacteria into ammonium to be used again by plants and bacteria.
How does nitrogen in the atmosphere move into soil?
Some of it is fixed by legume plants - or more precisely by bacteria in plant nodules.
Some gets there by when compounds created by lighting dissolve into the accompanying rain.
What is the process of changing free nitrogen into a usable form of nitrogen?
It is called nitrogen fixing.
Where can find lowest concentration of nitrogen in urine?
The lowest concentration of nitrogen can be found in the urine when it is first produced. As it accumulates in the bladder, so does the overall concentration of nitrogen.
How many grams of nitrogen and phosphorus are available in 1.00 pound of ammonium phosphate?
There is said to be about 600 grams of nitrogen in 1.00 pound of ammonium and 130 pounds of phosphorus available in 1.00 pounds of ammonium phosphate.
How do plants and animals get nitrogen is not from the atmosphere?
In rainforests where there is loads of leeching, plants get their nitrogen from other dead plants, where a nitrogen cycle is established
How atmospheric nitrogen enters the soil?
Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.
Is it true most nitrogen fixation is performed by plants?
No it is not true. Plants cannot fix nitrogen. Bacteria do the job
