B. Na2SO4
C. KCl
Answer:
B.
Explanation:
Hello,
The solubility of HgS is increased by adding due to common ion effect which consists on the effect that the higher solubility of has over the HgS as the sulfur-based ions modify the solubility product. In such a way, by adding the sulfate, the equilibrium will be shifted rightwards, therefore the solubility is increased.

Answer: Melting point of the naphthalene is 80.
Explanation:
Melting point of a substance is temperature at which given solid changes its state from solid to liquid. It is also referred as freezing point of the substance.
Freezing point of substance is a temperature at which given substance changes its state from liquid to solid.
Here, the solid piece of naphthalene is heated and remains at 80°C until it is completely melted.
The solid piece of naphthalene when heated is observed to melt after it attains the temperature of 80° C and then this 80° C is called as it melting point. After 80° C naphthalene will start to melt and get transformed into liquid state. Also if this naphthalene is allowed to cool down after 80° C it will be the freezing point of naphthalene.
Answer:
Explanation: Over pumping refers to pumping fresh water and reducing the level of an underground layer of water. In coastal areas, the lower underground layer of water is infiltrated with salt water, eventually increasing the salinity of the underground layer of water to the point that it is not drinkable. The scarcity of water in the coastal areas because the water in the coastal areas is not drinkable.
