Oil molecules repel each other electrically, leading to complete mixing of the two substances. Oil and water molecules have like charges, causing them to repel each other and separate. Oil and water molecules have like charges, causing them to repel each other and separate. Water molecules will attract each other electrically, but they will not attract oil molecules, causing separation. Water molecules will attract each other electrically, but they will not attract oil molecules, causing separation. Water and oil molecules have opposite electrical charges, causing them to repel each other and separate.

Answer 1

Water and oil molecules have opposite electrical charges, causing them to repel each other and separate.

Answer 2

The correct statement is: Water molecules will attract each other electrically, but they will not attract oil molecules, causing separation.

Answer 3

The correct statement is: Water molecules will attract each other electrically, but they will not attract oil molecules, causing separation.

When oil and water are stirred together, they do not mix or dissolve into each other because they have different properties. Oil molecules are hydrophobic, meaning they do not have an affinity for water molecules. Instead, oil molecules tend to stick together, forming clumps or droplets. This is due to the fact that oil molecules are nonpolar, while water molecules are polar.

In water, the oxygen atom has a slight negative charge, and the hydrogen atoms have slight positive charges. This polarity allows water molecules to form hydrogen bonds with each other, causing them to attract and stick together. However, oil molecules do not have a charge and do not form hydrogen bonds with water molecules.

Because of the differing properties between oil and water, when they are stirred together, the oil molecules will tend to clump together and separate from the water. This is why you will see oil floating on top of water or forming separate droplets when they are mixed.
