PLEASE HELP ASAP
Why can ionic table salt and covalent rubbing alcohol both dissolve in water?

Alcohol's polar bonds and salt's ions have higher potential energy than the potential energy of the hydrogen bonding between water molecules.

Alcohol's polar bonds and salt's ions are both able to form strong attractions to the polar water molecules.

The temperature of liquid water is high enough to allow anything to mix well with its fast-moving molecules.

The air pressure above the water is greater than the pressure exerted by the moving water molecules.

Whether or not a material will dissolve in another is dependent on the materials' attraction for each other. The stronger the attraction between solute and solvent particles, the greater the ability for them to mix and dissolve. I also just took the test and got it correct. I hope this helps!

The polar bonds of alcohols and salt ions are both able to form strong attractions to the polar water molecules.

In chemistry, the ability of a substance to dissolve in another depends on their ability to interact with each other in one way or the other.

Salt is an ionic substance so it can dissolve in water via interaction of the ions with the dipole in water.

Alcohol is covalent but contains polar bonds which can form hydrogen bonds with water. Such effective inter-molecular interaction leads to the dissolution of the substance in water.
