In nature, the two most common gases are Nitrogen and Oxygen. Air is about 78% N2, 21% O2, and 1% everything else (Hydrogen, Helium, Argon, etc.)
Nitrogen and Oxygen.
The two main gases are Nitrogen (N2) and Oxygen (O2), which comprise around 78% and 21% of the atmosphere by volume respectively. The remaining 1% is mostly Argon (Ar), followed by Carbon Dioxide (CO2) as well as several other gases present in trace amounts. All of these figures are for dry air, however water vapour (H2O) is also present in air at levels of up to 4%, but this is highly variable depending on localised conditions, and it makes up a lower percentage of the atmosphere as a whole.
The two biggies are Oxygen and Hydrogen. Traces can also be found of air, nitrogen, CO2, CO, CH3 and other gases in the atmosphere.
Noble gases do not react chemically with other noble gases.
True.
The carbon dioxide and oxygen are the two main gases in plasma. When blood travels to the lungs the concentration of these two gases changes.
There are many gases in the atmosphere. The two most common gases found in the atmosphere however, are nitrogen and oxygen.
