When we breathe in, we inhale the same mixture of gases contained in the atmosphere as our nose cannot filter out the oxygen from other gases. During the respiration process, the total composition of the air that we breathe in also depends on our surrounding environment.

It also prevents chemical oxidation by oxygen in normal air. An example is the rancidification (caused by oxidation) of edible oils. In food packaging, inert gases are used as a passive preservative, in contrast to active preservatives like sodium benzoate (an antimicrobial) or BHT (an antioxidant).

The most abundant naturally occurring gas is nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%. The inert gas argon (Ar) is the third most abundant gas at 0.93%. There are also trace amounts of carbon dioxide (CO2), neon (Ne), helium (He), methane (CH4), krypton (Kr), hydrogen (H2), nitrous oxi...
Due to the water cycle, the amount of water in the air is constantly changing. The lower troposphere can contain up to 4% water vapor (H2O) in areas near the tropics, while the poles contain only trace amounts of water vapor. The concentration of water vapor decreases drastically with altitude. The upper troposphere has less water vapor than air ne...
Air also contains tiny solid particles called aerosols, such as dust, sea salt, and ash from erupting volcanoes or forest fires. Many of these particles are so small that they are microscopic. Others are large enough to see. Aerosols affect climate by helping clouds form and shading the planet by scattering or absorbing sunlight. In the last centur...
Like everything on Earth, the air is made of chemicals. The chemicals in the air often combine with each other, or with other chemicals from the Earth’s surface, through chemical reactions. Many of these chemical reactions help maintain healthy natural environments and are vital for plants and animals. Nitrogen gas in the atmosphere does almost not...

Apr 26, 2018 · The majority of the air we breathe is made up of nitrogen and oxygen, though you'll also find argon, carbon dioxide and other gases in trace amounts. Nitrogen: Abundant and Inert. It’s a common misconception that oxygen is the most abundant gas in the air breathed on Earth; that honor goes to nitrogen, which makes up 78 percent of the air.

The mixture of gases that makes up the Earth’s atmosphere is known as air. Nitrogen makes up 78 % of this gas, which is mixed with oxygen (21%), water vapour (variable), argon (0.9 %), carbon dioxide (0.04%), and trace gases.

- Air is a solution as well: it’s a homogeneous mixture of gaseous nitrogen solvent and oxygen, as well as smaller amounts of other gaseous solutes.
- Air can be found almost everywhere on the planet, except where there is water. Air can even be found in the earth’s surface layer, in the soil. Air...
- The force that air exerts on objects is known as air pressure. As a result of the earth’s magnetic attraction force, all air in the atmosphere pres...

The six primary inert gases found in air are Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). These gases are used in various applications to prevent unwanted chemical reactions, such as oxidation and hydrolysis, which can degrade samples or materials.
