The rate of appearance of water to the initial rate of the disappearance of oxygen is 2:1.

Formation of H2O.

      2 H2 + O2 --> 2 H2O

From the equation,

we can conclude that 2 moles of water appear from 1 mole of O2 .

Water (H2O) is an inorganic, transparent, tasteless, odorless, and almost colorless chemical substance that is the major ingredient of the Earth's hydrosphere as well as the fluids of all known living species. Despite not providing food, energy, or organic micronutrients, it is essential for all known forms of life.

Its chemical formula, H2O, reveals that each of its molecules is made up of one oxygen and two hydrogen atoms that are linked together by covalent bonds. The hydrogen atoms are at an angle of 104.45° to the oxygen atom.

vlada-n [284]

Answer:

Sample A: Thymine= 20.7% ; Adenine= 20.7%; Guanine = 29.3% ; Cytosine= 29.3%

Sample B:  Thymine= 30.9% ; Adenine= 30.9% ; Guanine= 19.1% ; Cytosine base= 19.1%

Explanation:

In a double-stranded DNA molecule, the percentage of adenine base is equal to that of the thymine base while the percentage of guanine base is equal to that of the cytosine base. It is called Chargaff's rule and is based on the complementary base pairing of purine and pyrimidine bases.

Sample A: Percentage of thymine= 20.7%

This means that the sample has= 20.7% adenine base

Total thymine and adenine bases in sample A= 20.7 + 20.7 = 41.4%

Therefore, proportion of guanine + cytosine bases in the sample= 100-41.4= 58.6%

Percentage of guanine base= 58.6/2 = 29.3%

Percentage of cytosine base= 29.3%

Sample B: Percentage of thymine= 30.9%

This means that the sample has= 30.9% adenine base

Total thymine and adenine bases in sample A= 30.9 + 30.9 = 61.8%

Therefore, proportion of guanine + cytosine bases in the sample= 100-61.8= 38.2%

Percentage of guanine base= 38.2/2 = 19.1%

Percentage of cytosine base= 19.1%
