Find out the different components of air, What fraction do each. Component have in the air? Have these fractions remained the same over time? Has any action of mankind affected these fraction?Please answer me please

Answer:
Air is made up of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and other gases in meager amounts. Water vapor is also a constituent of air in varying amounts along with dust particles. The molar mass of dry air or air with no/low quantity of water vapor in it is 28.97g/mol. We can find out the average molar mass of a mixture of gases by using a simple formula in which we take the summation of the molar mass of each gaseous component multiplied by its mole fraction.

Answer:
Air, usually referred to as the atmosphere, is a mixture of several gases.
Step-by-step explanation:
Air's chemical composition is as follows:
- 78.09 percent nitrogen, 20.95 percent oxygen, 0.93 percent argon, 0.04 percent carbon dioxide, and trace amounts of other gases. Along with dust particles, water vapour is a component of air in variable proportions. Air that is dry or that contains little to no water vapour has a molar mass of 28.97g/mol.
- By applying a straightforward formula that takes the sum of the molar masses of each gaseous component multiplied by its mole fraction, we may determine the average molar mass of a mixture of gases.
- The most significant chemical constituent of air is oxygen. It has an atomic number of 8 and the symbol O. A highly reactive gas, oxygen easily forms oxide connections with other elements.
- A trace gas with a concentration of just 0.04 percent, carbon dioxide. Trace gases are gases that are found in the atmosphere, but only in extremely minute quantities.
- Nitrogen, which makes up 78 percent of the air, is the most plentiful and pure element. It has an atomic number of 7 and the letter N.
- Argon is the third most prevalent element in the atmosphere, with a concentration of 0.93 percent. A noble gas, that is. Argon has the atomic number 18 and the symbol Ar.
- Depending on the temperature, the amount of water vapour in the atmosphere ranges from roughly 0.01 percent to 4.24 percent.
- Dust particles are small, solid particles. Aeolian dust is another name for atmospheric dust. These particles include those that come from soil, pollution, or volcanic eruptions.
Thus, air pollution worsens the symptoms of those who are already unwell and raises the risk of respiratory infections, heart disease, stroke, and lung cancer. Air pollution has disproportionately negative health consequences on children, the elderly, and residents of low-income areas.
