Answer:
Ion exchange.
Explanation:
One of the ways in which water can be treated is through the process known as ION EXCHANGE. Using this for treating water has to do basically with the transfer or say the exchange of ions.
Ion exchanges is done by exchanging ions which are considered as 'unfit' or contaminants by the ones that are "fit".
Ions from what is known as zeolite or resin is been exchanged with the ions in the water. Cations are exchanged with cations and anions are exchanged with anions.
NB: this method is a good method or removing contaminants that are ions but not contaminants that are not ions.
Sulphur is found in 23 isotopes ranging from 27 to 49.
Also, magnitude of average atomic mass is more toward the isotope which is the most abundant.
Now , molecular mass of Sulphur is 32.06 u . It means the most abundant isotopes of Sulphur is 32.
It can also be verified by the fact that 95 % of natural occurring sulfur is .
Hence, this is the required solution.
The atomic mass of a carbon atom is 12. 011 u. convert this mass to units of kilograms and MeV are 12.011 × 10^(-3) kg and 11182.24MeV.
<h2>What is atomic mass? </h2>
The mass of an atom of a chemical element which is expressed in atomic mass units is termed as atomic mass.
Given,
the atomic mass of carbon atom = 12.011u
As we know that
1u = 1g
12.011u = 12.011g
So. the atomic mass of carbon atom in g = 12.011g
<h3>Atomic mass in Kg</h3>
1 Kg = 1000g
1g = 10^(-3)Kg
12.011g = 12.011 × 10^(-3) kg.
<h3>Atomic mass in MeV</h3>
1u = 931MeV
12.011u = 12.011 × 931MeV
= 11182.24MeV
Thus, the value of atomic mass of carbon atom in Kg and MeV are 12.011 × 10^(-3) kg and 11182.24MeV.
