N2 characteristics is cool and O2 is hot, so its help to cool o2 before take
breath in our body.
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.
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
Nitrogen, N2 and oxygen, O2
More NO would form
Exhaled breath is mainly composed of nitrogen, oxygen, carbon dioxide, and water vapor. Therefore, the general chemical formula for exhaled breath would be similar to the chemical composition of air, which is approximately N2 + O2 + CO2 + H2O.
The air you breath is approximately 21% O2 when you breath out its about 15% O2. When you breath into a person, you are breathing for them. Its the same thing as if they were breathing on there own, only less O2 concentration. The air still goes down to their lungs.
The bond order of N2 is 3, and the bond order of O2 is 2.
78% N2 21% O2 0.04% CO2 and a little water vapour
More N2 and O2 would form
Contains normal air composed of N2, O2, water vapour, CO2, etc.
Mouth-to-mouth resuscitation works by providing oxygen to a person who is not breathing. By blowing air into their lungs through their mouth, you are helping to deliver vital oxygen to their body. This can help sustain life until more advanced medical help arrives.
The balanced equation for the reaction between nitrogen (N2) and oxygen (O2) to form nitrogen dioxide (NO2) is: 2N2 + 4O2 -> 4NO2
