No scientist in this or the last century. Air is mostly nitrogen, about a fifth oxygen and traces of several other gasses.

What elements react with oxygen?
Oxygen is an element and therefore is only contained by itself. However, it can be abstractly said that all elements with atomic numbers above eight "contain" oxygen, because if you removed enough neutrons, protons, and electrons from any element above 8, you would have oxygen. (Or at least, you would have an unstable atom).
Is a carrot a pure substance?
its not a mixture because i had a test on it and it said it was a pure substance.
How does fermentation does not require oxygen it is said to be?
Anerobic respiration
Whats the difference between homogenous mixture and heterogeneous mixture?
In a homogenous mixture the substance are so evenly distributed that it is difficult to distinguish one substance in the mixture from another but it only contains only one substance and it will appear the same. In a heterogenous mixture the parts of the mixture are noticeably different from one another and the mixture is different and kind.
Why is water said to be a compound instead of an element?
If a substance is made up of a combination of atoms, then it is called a compound. Hence a water molecule (which is composed of three atoms, two hydrogen and one oxygen) is a compound. Most materials are compounds. Only the noble gasses (like helium) exist in their elemental form naturally.
Air is mostly composed of?
Im pretty sure its composed of elements that are nonmetals. taking a test recently said that they were not noble gasses.
Is oxygen a compound or a mixture?
oxygen not a mixture, it was the combination of two atoms, so it is said to be compound. in this the two oxygen's are form two strong sigma bonds in b/w them.
What does engine running rich or lean mean?
An engine runs by the combustion of a mixture of oxygen and gasoline. If this mix has too much oxygen, it is said to run lean. When the mixture has too much gasoline in relation to oxygen, it is running rich.
Why compression and combustion are always adiabatic process?
Adiabatic compression occurs when a precisely controlled mixture of a flammable gas and oxygen are ignited by the heat of colliding molecules during the compression of said gas. This causes an explosion and the explosion causes an expansion of the gasses. These expanding gasses must force their way out of confinement and pushes a piston. This turns tirns a crank shaft which will mechanically open and close intake and exhaust valves through push rods.
Oxygen as a common oxidizing agent?
Yes because n2o is 2 atoms of nitrogen and one of oxygen and is said like nitrous oxide which is used in some of the cars TEACH THEM HOW TO NOT USE IT WHEN RAINING!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
How is water capable of dissolving gasses and nutrients?
because the hydrogen bonds in water will readily detach themselves from the oxygen molecules to form stronger bonds with other said molecules.
What is the air entering the body?
well the air is made up of soo many gasses but the main ones are carbon-dioxide, argon, oxygen and nickel. we breathe them mainly, but as i said, we breathe many others too...
Why does Russia produce metals oils and gasses?
cause i said so
A molecule is said to be organic if it contains?
An organic molecule is a molecule and that contains carbon atoms that are connected to hydrogen, oxygen or nitrogen atoms. Glucose has carbon, hydrogen and oxygen atoms so it is organic.
What are the 6 elements most important in biology?
To generalise, the substances that we actually need to survive in the first place is oxygen and water. These consist of hydrogen atoms and oxygen. Carbon is also very important as most things are made from carbon (along with other elements).Also, elements such as berylium, boron and lithium are not necessary but they are in the first 6 elements.Technically, the answer is no (but some of the elements are very important as I have said above).
Where is nitrogen commonly found in?
Nitrogen is commonly found in a atmosphere. And whateverr that chick next to me said.
It is said that the nitrogen-containing bases of DNA are?
