What is the primary function of an emulsifier when added to a mixture of oil and water?

To increase the boiling point of the water.

To chemically break down the oil molecules.

To prevent the oil and water from separating into layers.

To change the color of the mixture.

What unique structural feature allows an emulsifier molecule to interact with both oil and water?

It has two distinct ends: one that is attracted to oil and one that is attracted to water.

It carries a strong electrical charge.

By connecting to both an oil droplet and a water molecule, holding them together.

By forming a solid wall between the oil and water to stop them from touching.

By reacting with water to make it chemically identical to oil.

By absorbing all the oil, making it seem to disappear into the water.

The oil is less dense and is repelled by the water molecules, causing it to float on top.

The shaking process causes the oil to evaporate, leaving only the water behind.

The water becomes denser than the oil and sinks to the bottom.

A chemical reaction occurs that forces the two liquids apart.
