Why air contains N2 and O2 instead of NO?
Elements prefer to live in their natural forms.N2 and O2 are more stable than NO.Added:Air is a mixture of N2 and O2 molecules, where NO is a compound, chemically formed by reaction: N2 + O2 --> 2 NO. This reaction does not take place at normal conditions as in the air around us.
What is the percent of composition of air expired in with O2?
The composition of air expired is approximately 16% oxygen (O2) and 4% carbon dioxide (CO2), with the remaining 80% being nitrogen (N2) and trace gases.
What is the partial pressure of 20.84 percent of O2 in air?
The partial pressure of a gas in a mixture is equal to the total pressure of the mixture multiplied by the mole fraction of that gas. Since the mole fraction of O2 in air is 0.2084 and the total pressure of air is approximately 1 atmosphere, the partial pressure of O2 in air is approximately 0.2084 atmosphere.
What is lightning good for?
It naturally creates ozone (O3) from the oxygen (O2) in the air.
Is air a compound element heterogeneous or homogeneous mixture?
Air is a homogeneous mixture of several gases.
How plants help to maintain the percentage of gases in air?
They reduce CO2 and increase O2.
How do plants help to maintain the percentage of gases in air?
They reduce CO2 and increase O2.
How do plants maintain the balance of o2 and co2 in the atmosphere?
Plants convert CO2 to O2 in air. The green pigment in their leaves is due mainly to chloroplasts. These help to absorb light and use this energy to convert CO2 back to O2 (a thermodynamically unfavourable reaction)
Where is the O2 Sensor Located on a CRX?
The O2 sensor can be found on the outside of the air cleaner housing. The O2 sensor will be attached to the back of the air cleaner housing.
Is the O2 in the air you breathe a cell?
no
What important substance is in the air when you inhale?
O2
If Nitrogen is 78 percent of air then how many percent of o2 in the air?
21%
Is the O2 in the air you breathe an electron particle?
There are electron particles in O2 as well as in every thing in your body.
Where are the O2 sensors vw passat?
The VW O2 sensor is located on the outside of the air cleaner housing. The sensor can be found on the back of the air cleaner housing.
What air does kelp give off?
Oxygen (O2)
What does magnesium react with when burnt?
Oxygen in the air (O2)
What percentage of exhaled breath is CO2?
The air we breath in is roughly 21% O2 and 0.04% CO2 and we breath out air that is 16% O2 and 4% CO2
