Which of the following statements is false?

(A) The solubility of gases in water decreases with increasing temperature.
(B) The solubility of a gas increases in direct proportion to its partial pressure above the solution.
(C) Substances with similar intermolecular attractive forces tend to be soluble in one another.
(D) The weaker the attraction between the solute and solvent molecules, the greater the solubility.
(E) Nonpolar liquids tend to be insoluble in polar liquids.

The weaker the attraction between the solute and solvent molecules, the

greater the solubility is False.

A  solution comprises of a solute and solvent. Solubility depends on the

interaction of the solute and the solvent. A greater form of interaction or

attraction signifies a higher solubility.

This means that the weaker the attraction between the solute and solvent

molecules the lower the solubility and vice versa

The weaker the attraction between the solute and solvent molecules, the greater the solubility.

Explanation:

Solubility depends strongly on the degree of interaction between solute and solvent molecules. A strong interaction between solute and solvent molecules implies that the solute will effectively dissolve in the solvent. A weak interaction between solute and solvent molecules means that the solute cannot dissolve in the solvent at all. For instance, common salt cannot interact with kerosene hence common salt is insoluble in kerosene at all temperatures.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
