What is the formula for one nitrogen atom and one oxygen atom?

Answer 1

The molecule that contains one nitrogen atom for two oxygen atoms is NO2 or nitrogen dioxide. This compound is one of several oxides of nitrogen, and it is a primary constituent of air pollution, where we most commonly encounter it. NO2 appears in vehicular exhaust, and is responsible for a good portion of the "haze" that we often call smog. We know nitrogen is the major constituent of atmospheric gas at about 80%, and oxygen is about 20%. (Yes, that equals 100%, and there are other things in air, but this is a ball park estimate cited to answer and add a little information to speak to this question.) Let's look at the pollution a bit.

The oxygen is used when the fuel is burned in the engines, but the nitrogen is heated and left largely uncombined in the combustion process. Though most all the oxygen in the air in the combustion chambers is combined to burn the fuel, the fuel is not completely burned, so we use emission control systems. Air injected by the "smog pump" on cars forces air into the exhaust headers. The idea is to provide oxygen to unburned (but very hot) partially combusted fuel and get it to "completely" oxidize to reduce the emissions. But the oxygen also combines with the hot nitrogen in the exhaust stream to create the nitrogen dioxide.

It turns out that NO2 has a reddish brown color to it, and if you look at an urban sky where stagnant air results from impaired atmospheric circulation, the sky takes on a reddish brown (a "dirty brown") look because of the nitrogen dioxide concentrating in that air. Though nitrogen dioxide is a common industrial chemical produced as an intermediary in a number of reactions, it is in the form of air pollution that we most frequently encounter it.

Answer 2

This chemical formula is for dinitrogen tetroxide.
This compound is a very strong oxidizer and is used as a rocket propellant.

Answer 3

N2O4 or NO2 are the chemical formula for the two nitrogen atoms for every four oxygen atoms.

Answer 4

This compound is dinitrogen trioxide - N2O3.

Answer 5

This compound is dinitrogen trioxide - N2O3.

Answer 6

The formula for one nitrogen atom is N, and for one oxygen atom it is O. When these two atoms combine, they can form nitrogen monoxide, which has the chemical formula NO.

Answer 7

NO of course, N it nitrogen, O is oxygen

Answer 8

If a molecule has 2 nitrogens and 3 oxygens, what is the molecular formula?
