Density of the vinegar is higher than the density of the oil.
Explanation:
Density of the vinegar is higher than the density of the oil. The consequence of this is that the oil will be the top layer in the pitcher while the vinegar is at the bottom layer in the pitcher.
When mixing oil and vinegar will not produce a mixture because the oil contains non-polar molecules while vinegar is a solution of acetic acid in water and both of them are polar molecules.

Answer:- B. Solvent molecules surround solute ions.
Explanations:- When an ionic solute that has positive and negative ions is dissolved in a solvent like water then the solute ions are surrounded by the water molecules in a way so that the highly electron negative oxygen atom of water is towards the positively charged ion of the solute and less electron negative which is hydrogen atom that has partial positive charge, surrounds the negatively charged ion of the solute.
Due to these forces made by the solvent molecules, the solute is broken into the ions and get dissolved in solvent.
