Answer:
A solution of CH3Cl will not conduct electricity
Explanation:
Ionic substances conduct electricity because the solution is composed of ions. Ions are charge carriers in a solution. When an ionic substance is dissolved in water, the substance dissociates into its component ions. The concentration and activity of these ions determines the conductivity of the solution.
However, molecular substances are not composed of ions. Since they are not composed of ions, they do not dissolve in water to yield ions. This implies that solutions of molecular substances are do not conduct electricity.
CH3Cl is a molecular substance. It is not composed of ions, hence its solution does not conduct electricity.
Answer : The boron-11 isotope is the most abundant.
Explanation :
As we are given that:
Average atomic mass of boron = 10.81 amu
Mass of boron-10 = 10.0129 amu
Mass of boron-11 = 11.0093 amu
As we know that the average atomic mass of an element is always closest to the most abundant isotope.
Out of the two boron isotopes, B-11 is closest in mass to the weighted average. Therefore, it is the most abundant.
Hence, the boron-11 isotope is the most abundant.
The answer is B, the number of protons
It's is the unique thing about every element!
