Air is a mixture of gases! To answer this question you need to define what gas percentage as a component of air you are requesting information on.
A diatomic gas.
Air contains approximately 78% nitrogen gas.
Haven't a clue. No websites show this.
78.09% Nitrogen by Volume (approx)
About 79% of earth's atmosphere is Nitrogen.
78 percent Air is mostly gas The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
Nitrogen, close to 80 %.
The element Nitrogen has by far the highest % composition of dry air. It is also the highest percentage by volume in wet air. Only the percentage is known (78.09%), because it is impossible to measure the total volume of air as it is constantly changing.
Yes. Nitrogen makes up about 78.08% of the air in Earth's atmosphere by volume.
CO2 (carbon dioxide)
about 78% of air is nitrogen 21% oxygen, and 1% other gasses e.g. carbon monoxide, water vapour etc.
The Lower Explosive Limit (LEL) of natural gas (which is primarily methane). is 5% by volume in air. The Upper Explosive Limit (UEL) is 15% by volume in air
The percentage of oxygen in air is 21%.
Primary air is the air that mixes with the gas before the gas is burned.
Yes it is. Air Gas.
air is a substance because air is a gas and a gas is a substance.
Atmospheric (external) air contains a high percentage of oxygen and nitrogen whereas alveoli gas contains a lower percentage of oxygen and a higher percentage of carbon dioxide. The differences in composition are due to the fact that gaseous exchange is taking place within the alveoli in the lungs. Oxygen is diffusing from the alveoli into the pulmonary artery and carbon dioxide is diffusing back into the alveoli from the pulmonary artery due to the concentration gradients. This is the main reason why external air and alveolar gas have such different compositions. Another reason why the gas compositions are different is due to the fact that alveoli gas contains a mixture of both atmospheric air which has been inhaled and 'old' air which stays in the respiratory track and is not exhaled after each breath therefore giving it a different composition. Alveolar gas has a larger percentage of water vapour than atmospheric air due to the fact that air is being warmed and moistened as it travels into the respiratory track. This is done by the mucus in the nasal cavity as the air travels past it.
The air we breathe.
This gas is nitrogen (78,08 %) in air.
Air is a gas.
Yes, air is a gas.
