This is not the best way to organize a periodic table because two elements might have similar atomic mass.
<h3>What is periodic table?</h3>
Periodic table is a chart in which arrangement of chemical elements are done.
In the early periodic table elements are arranged on the basis of their atomic masses, while after sometime Moseley arranged the periodic table on the basis of atomic number as he proposed that properties of an element is justified on the basis of number if electrons.
And mass of two substances may be same so it is difficult to differentiate between them.
Hence, two elements might have similar atomic mass.

Protium - the most common isotope of hydrogen - has no neutrons in its nucleus.
Adding a catalyst as this would speed up the reaction and the rest would slow it down
Answer:
See explanation
Explanation:
Racemization is said to occur when a 1:1 ratio of (+) and (-) enantiomers of a compound are produced in a reaction.
The reaction of optically active (R)-2-methylcyclohexanone with either aqueous base or acid leads to the formation of a planar enol species for reaction with acid and a planar enolate species for reaction with base.
Both reactions involves the formation of achiral species which reverts back to the chiral product with equal chances of the formation of both enantiomers of the product during the process. This leads to racemization of the product in both cases.
Answer:
1 L
Explanation:
ppm means parts per million. Generally the relationship between mass and litre is given as;
1 ppm = 1 mg/L
This means that 1 ppm is equivalent to 1 mg of a substance dissolved in 1 L of water.
