1. how does a solute dissolve into a solvent?

oa) polar solvent molecules separate the molecules of other non - polar substances.
b) non - polar solvent molecules separate the molecules of other non - polar substances.
oc) polar solvent molecules separate the molecules of other polar substances.

1. what is the definition of a solute?

a) water
b) what gets dissolved into a solvent.
c) a mixture of two solutions.

Explanation:

• For question 36, solubility is defined as the ability of a solute to dissolve in a solvent.
• For question 37, in reality, there is always some small - scale dissolution even for so - called insoluble compounds, so the statement is false.
• For question 38, polar solvents dissolve polar solutes because of similar intermolecular forces (like dipole - dipole interactions).
• For question 39, a solute is what gets dissolved in a solvent.

Answer:

1. A. The ability of a given substance(solute) to dissolve into a solvent.
2. False
3. C. Polar solvent molecules separate the molecules of other polar substances.
4. B. What gets dissolved into a solvent.
