Air is composed primarily of what 2 gasses?
Air is primarily composed of nitrogen (about 78%) and oxygen (about 21%).
Is Nitrogen found in Dry Air?
Yes, nitrogen is found in dry air. Dry air is primarily composed of nitrogen (about 78%) and oxygen (about 21%), with trace amounts of other gases.
What forms does nitrogen appear in the air?
Nitrogen appears in the air primarily as diatomic nitrogen molecules (N2), which make up about 78% of the Earth's atmosphere. Nitrogen gas makes up a significant portion of the air we breathe and plays a crucial role in various biological and chemical processes.
Is air mostly oxygen and nitrogen a mixture or compound?
Air is mostly a mixture of gases, primarily nitrogen and oxygen. Nitrogen makes up about 78% of air, while oxygen makes up about 21%. These gases are not chemically bonded and can be separated from each other.
Is air flammable?
Yes, air is not flammable because it is a mixture of gases, primarily nitrogen and oxygen, which do not readily support combustion.
Air is composed primarily of what 2 gasses?
Air is primarily composed of nitrogen (about 78%) and oxygen (about 21%).
During one part of the nitrogen cycle nitrogen is removed from the air by mainly by nitrogen-fixing?
bacteria
What are 2 elements found in the air?
The air is primarily composed of nitrogen and oxygen. About 78% Nitrogen, Oxygen 21%.
Is Nitrogen found in Dry Air?
Yes, nitrogen is found in dry air. Dry air is primarily composed of nitrogen (about 78%) and oxygen (about 21%), with trace amounts of other gases.
How is nitrogen removed from an echo system?
Nitrogen is removed from an ecosystem primarily through the process of denitrification, where specialized bacteria convert nitrates in the soil into nitrogen gas, which is then released into the atmosphere. Additionally, nitrogen can be removed through plant uptake, where plants absorb nitrogen compounds for growth, and through leaching, where nitrogen is washed away from the soil into waterways. These processes help maintain nitrogen balance and prevent excessive accumulation, which can lead to environmental issues like eutrophication.
When is nitrogen removed when harvesting crops?
Nitrogen is removed from the soil during the harvesting of crops primarily when the plants are cut and removed from the field. As crops grow, they absorb nitrogen from the soil, and when the above-ground biomass is harvested, the nitrogen contained in the plant material is also taken away. This can lead to a depletion of nitrogen in the soil, necessitating appropriate soil management practices, such as crop rotation or the application of fertilizers, to replenish nitrogen levels for future planting.
When does nitrogen leave the air?
Nitrogen leaves the air as it is absorbed by plants through their roots for growth and development, as well as through the process of nitrogen fixation by certain bacteria in the soil. Additionally, nitrogen can be removed from the air through lightning strikes, where nitrogen gas is converted into compounds that can be deposited on the earth through rainfall.
Does titan have air?
Yes. Titan has a very dense atmosphere composed primarily of nitrogen.

Yes, air is not flammable because it is a mixture of gases, primarily nitrogen and oxygen, which do not readily support combustion.
Do humans need nitrogen to breathe for survival?
No, humans do not need nitrogen to breathe for survival. The air we breathe is primarily made up of oxygen, with only a small amount of nitrogen.
