Nitrogen is the most abundant gas in Earth's atmosphere, making up about 78% of the air we breathe, while oxygen makes up about 21%. Both gases play crucial roles in supporting life on Earth by being essential for various biological processes.
Yes, proteins are made up of carbon, hydrogen, oxygen, and nitrogen. These elements are arranged into amino acids that form the building blocks of proteins.
Nitrogen is lighter than oxygen. The atomic weight of nitrogen is approximately 14, while the atomic weight of oxygen is approximately 16.
True. Our air is 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, and traces of hydrogen, helium and about 1% water vapor.
Nitric oxide + oxygen => Nitrogen Dioxide
While nitrogen is a non-combustible gas that can be used to extinguish fires, it is not entirely accurate to say that without nitrogen in the air, a fire will not burn. Fires require oxygen to burn, and while nitrogen dilutes the oxygen concentration in the air and can help suppress fires, it is not the absence of nitrogen that prevents fires from burning.
False. Almost all of the oxygen on Earth is found in the oceans.
This statement is not accurate. The two major components of Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%), not hydrogen. Hydrogen is present in trace amounts in the atmosphere.
Yes. But nitrogen is inactive.
No. There is more nitrogen. Nitrogen is 78% while oxygen is 21%. The rest is a mixture of other gases.
It is not rues at all. Most of the gas inhaled is not oxygen it is nitrogen.
they are both made of protons, neutrons, and electrons

No; the given statement is false. The natural atmosphere is largely a homogeneous mixture of oxygen and nitrogen gases, and it has very different chemical properties form any of the compounds formed from nitrogen and oxygen. Distinct such compounds with formulas N2O, NO, NO2, and N2O5 are known and are all chemically different from one another as well as from a homogeneous mixture of oxygen and nitrogen gases.
Good old air contains more Nitrogen than oxygen.
Yes, it is true because the density of oxygen is higher than the density of nitrogen.
No, nitrogen does not burn in oxygen. Nitrogen is inert and does not react with oxygen under normal conditions.
