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

What is soluble nitrogen?

Soluble nitrogen refers to nitrogen compounds in soil that can dissolve in water, making them available for plant uptake. It includes forms such as ammonium (NH4+) and nitrate (NO3-). These forms of nitrogen are important for plant growth as they are readily accessible for use by plants.

What can you infer from the fact that animals do not need nitrogen?

If you are told it is a fact that animals do not need nitrogen, you can infer that you are receiving incorrect information.

All living things require nitrogen. However, animals are not able to obtain the nitrogen they need directly, but must get it from their food, and that comes ultimately from the plants that are able to absorb nitrogen from the soil.

How do plants and animals get nitrogen if not from the atmosphere?

if not from the atmosphere , they must depend on a process called nitrogen fixation.

They get it from the soil. That's why farmers add fertilizer to the soil to increase nitrogen content

Is there nitrogen in salt?

In the Nitrogen Cycle, a lot of Plants and depend upon nitrogen for growth. Nitrogen is needed to form amines and amino acids. These two chemical groups combine to make different proteins. The proteins are used for cell growth and repair in plants and humans.

Why is free nitrogen a problem for organisms?

Free nitrogen is a problem for organisms because most organisms cannot directly use nitrogen gas (N2) in the atmosphere. Instead, they require nitrogen in a usable form like nitrate or ammonium to build essential molecules like proteins and nucleic acids. Some specialized organisms, like nitrogen-fixing bacteria, can convert free nitrogen into a usable form through a process called nitrogen fixation.

How is soil a nitrogen reservoir?

Soil acts as a nitrogen reservoir by absorbing and storing nitrogen from various sources such as organic matter, fertilizer application, or atmospheric deposition. This stored nitrogen is available for uptake by plants and can be converted into different forms by soil microorganisms, contributing to nutrient cycling in the ecosystem.

What is nitrogen valency in nitrogen pentoxide?

There is one atom in nitrogen

there is not one atom of nitrogen, there is one molecule of nitrogen.

There is 6.02 * 10^23 atoms in 1 mole of nitrogen.

Or simply the natural state of nitrogen is n2. or two nitrogen atoms to a molecule. =]

How do heterotrophs get their nitrogen?

Heterotrophs obtain nitrogen by consuming organic matter containing proteins or amino acids. They break down these complex molecules into simpler forms through digestion, allowing them to absorb and utilize nitrogen for various cellular functions.

What is nitrogen RAM?

Nitrogen RAM refers to a technology where nitrogen gas is used as the cooling medium for computer memory modules. This allows for more efficient heat dissipation compared to traditional air or liquid cooling solutions, which can potentially improve performance by allowing higher overclocking capabilities. However, it is not commonly used due to the complexity and cost associated with nitrogen cooling systems.

Do baseballs have nitrogen in them?

Yes, baseballs are typically made with a rubber or cork center, which may contain small amounts of nitrogen. Nitrogen gas can also be used to inflate the baseball to a specific pressure level for optimal performance.

What is it called when nitrogen taken into the body exceeds nitrogen losses?

When nitrogen taken into the body exceeds nitrogen losses, it is referred to as positive nitrogen balance. This usually occurs during periods of growth, recovery from illness, or when physical activity promotes muscle synthesis over breakdown.

How do you spell nitrogen?

nee-chro-geen Niy*tchro*jen or Ni*tro*gen Hope that helps

What is the confiruration of nitrogen?

The configuration of nitrogen in its ground state is 1s2 2s2 2p3, with five electrons occupying the 1s and 2s orbitals, and three electrons in the 2p orbital. This gives nitrogen a total of seven electrons.

Does nitrogen boil?

Yes. At atmospheric pressure, nitrogen boils at -320 degrees Fahrenheit.

What are methods of nitrogen fixation that complete the nitrogen cycle?

nitrogen fixation takes place with the help of lightning , bacteria called rhizobium lives in the nodules of legumenous plants convert nitrogen into nitrogeous compounds , algae etc. also helps in nitrogen fixation

How is the nitrogen from a dead animal converted back to thr nitrogen?

When a dead animal decomposes, bacteria and fungi break down the organic matter, releasing nitrogen-containing compounds into the soil. Other bacteria then convert these nitrogen compounds back into atmospheric nitrogen through a process called denitrification. This atmospheric nitrogen can then be taken up by plants and reused in the ecosystem.

What is the difference between fixed nitrogen and free nitrogen?

Fixed nitrogen refers to nitrogen that has been converted into a form that can be readily used by plants, such as ammonia or nitrates. Free nitrogen, on the other hand, refers to nitrogen gas (N2) that makes up about 78% of the Earth's atmosphere and is not readily available for use by most organisms until it is fixed.

When and where was nitrogen discovered?

Nitrogen was discovered in the late 18th century by the Scottish physician Daniel Rutherford. He didn't exactly throw a party to announce his discovery, but he did it in 1772 at the University of Edinburgh. So, there you have it, nitrogen's debut on the scientific stage.

What is the difference between free nitrogen and fixed nitrogen?

Free nitrogen refers to the nitrogen gas (N2) present in the atmosphere, which is not readily available for use by most organisms. Fixed nitrogen, however, is nitrogen that has been converted into a form that can be utilized by plants and other organisms, such as ammonia, nitrate, or nitrite. This conversion process is often carried out by nitrogen-fixing bacteria in the soil.

How do you separate Nitrogen from Liquid Nitrogen?

Nitrogen only remains a liquid at very low temperatures (-196oc) above this temperature the liquid will return to a gas, so warm it us is the answer, although because of the extreme cold temperatures and the asphyxiating nature of the gas it needs to done safely and only by trained personnel using the correct equipment.

Why is nitrogen fixation necessary?

Most plants use single nitrogen atoms, not N2 molecules.

Why is compost rich in cellulose likely to be poor in containing nitrogen?

That it is considered a brown-colored, carbon-rich recyclable is a reason why compost rich in cellulose is likely to be poor in nitrogen. Dark-colored, fresh-smelling, nutrient-rich organic matter called compost or humus originates in and possesses carbon and nitrogen from respectively brown-colored, dead, decaying, dying and green-colored, living recyclables. The chemical formula for cellulose reveals contributions from carbon, hydrogen and oxygen: C6H10O5.

What are the differences between atmospheric nitrogen and laboratory nitrogen?

Chemical nitrogen 1 it is pure as it does not have any inert gases. 2 it is lighter compared to atmospheric nitrogen. 3 it is highly reactive. Atmospheric nitrogen 1 it has 1% inert gases. 2 it is heavier than chemical nitrogen due to the dust particles. 3 it is less reactive because of the inert gases.

The process of converting nitrogen into nitrogen compounds by bacteria is called What?

The process of converting nitrogen into nitrogen compounds by bacteria is called nitrogen fixation. This process is essential for making nitrogen available for plant uptake and for supporting all forms of life.

What is refractory nitrogen?

Refractory nitrogen refers to nitrogen compounds that are resistant to breakdown by microbial activity in soil, making them less available to plants. These compounds can accumulate in soil over time, impacting nitrogen cycling and plant growth. Examples include organic nitrogen compounds like lignin and humus.
