Which of the following compounds, when added to water, is most likely to increase the solubility of HgS?A. KNO3
B. Na2SO4
C. KCl

Answers

Answer:

B. Na_2SO_4

Explanation:

Hello,

The solubility of HgS is increased by adding Na_2SO_4 due to common ion effect which consists on the effect that the higher solubility of Na_2SO_4 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.

Best regards.

C. KCl- That is the answer for sure, but I dont want to explain

Answers

Answer: Melting point of the naphthalene is 80^oC.

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.

Answer  : Freezing and Melting point

Explanation :

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.
