Answer:
B. Conductivity can be used to calculate the salinity of the water.
I am 100% sure this is the correct answer :)
Answer:
Convention currents are found in the asthenosphere part present in the mantle of the Earth.
Explanation:
The Mantle is the middle layer of the earth surface extending up to 2900 kilometers.
Beneath the Mantle lies the core which contains molten rocks and materials called magma.
The materials are highly radioactive and immensely heated. These highly hot condition creates pressure on the middle layer (Mantle).
As a result, large convention currents are generated excessively
The conductance of the electric current through the electrolytic solution increases with increase in concentration.
<h3>What is electrolysis?</h3>
The term electrolysis has to do with a situation in which liquids conduct electricity by the movement of ions.
The conductivity of the solution depends on the ions present in the solution. Thus, the conductance of the electric current through the electrolytic solution increases with increase in concentration.

The value of pka for
in an aqueous solution is 9.2.
<h3>What is Kb?</h3>
Kb denotes the base dissociation constant.
pKa + pKb =14 at 25 degree celcius.
pKa + 4.8 =14
pKa = 9.2
pKb is the negative base-10 logarithm of the base dissociation constant (Kb) of a solution.
It is used to determine the strength of a base or alkaline solution.
The value of pka for
