Answer:

Option C = Ozone

Explanation:

The Percentage of given gases in atmosphere:

Oxygen = O₂ = 20.95 %

Nitrogen = N₂ = 78.08%

Argon = Ar = 0.93%

Ozone = O₃ = 0.000004%

Nitrogen is most abundant gas in atmosphere while oxygen is second most abundant gas. The nitrogen and oxygen are present in diatomic form such as O₂ and N₂.

Water vapors are also present but the percentage vary according to location. In hot humid areas the percentage of water is 0- 4% and it is third abundant gas.

The percentage of other gases in atmosphere are given below:

CO₂ = 0.0360%

Ne = 0.0018%

He = 0.0005%

CH₄ = 0.00017 %

N₂O = 0.0003%

H₂ = 0.00005%

garik1379 [7]

Answer:

The correct answer is- A) two, B) yes, the number is the same as monosaccharides.

Explanation:

There are three atoms are present in a molecule of water which includes two atoms of the hydrogen and one atom of the oxygen. The hydrogen atom is two times larger in the number of the oxygen atom in a single molecule of the water.

In monosaccharides, the ratio of the atoms of carbon, hydrogen, and oxygen is 1:2:1 which means one hydrogen atom would be twice in the number of the carbon and oxygen atoms in a single molecule of monosaccharide molecule.

Thus, the correct answer is - A) two, B) yes, the number is the same as monosaccharides.
