Answer:
Vegetable oil will dissolve in heptane
Isopropyl alcohol will dissolve in water
Potassium Bromide will dissolve in water
Explanation:
In chemistry, like dissolves like. This implies that polar substances will dissolve in polar solvents and nonpolar substances will dissolve in nonpolar solvents. This is so because, dissolution of a solute in a solvent involves adequate intermolecular interaction between solute and solvent which isn't possible between a polar and a nonpolar substance.
Vegetable oil will dissolve in heptane
Isopropyl alcohol will dissolve in water
Potassium Bromide will dissolve in water
In terms of chemistry, like dissolves like. This represent that polar substances should dissolve in polar solvents and nonpolar substances should dissolve in nonpolar solvents. This is due to dissolution of a solute in a solvent involving enough intermolecular interaction that lies between solute and solvent which can't be possible between a polar and a nonpolar substance.
