Help needed <3

Answer 1

Answer: Option (C) is the correct answer.

Explanation:

Solubility of solute depends on temperature because on increasing the temperature solute particles colloid more frequently. As a result, there is increase in rate of reaction, that is, increase in solubility of solute into the solution.

Also, the nature of solvent is important in determining its solubility because a polar solute will only dissolve in a polar solvent whereas a non-polar solute will dissolve only in non-polar solvent.

Thus, we can conclude that the solubility of a solute depends on the nature of the solute and the temperature.

Answer 2

The answer to this question would be C. Because some natural elements can't be mixed with certain solubles and won't work as effectively as other solutes. And the temperature affects the rate the solute works in. So, C is your answer.
