Do water molecules attract nonpolar molecules such as oil?
Yes, but they attract polar molecules more strongly."Hydrophobic" molecules is a misnomer. The nonpolar molecules in question are attracted to water molecules (usually more strongly than they're attracted to each other, even), but they get "shoved out of the way" by polar "hydrophilic" molecules which are even more strongly attracted to water molecules.
Is oil denser than of vinegar?
Yes, oil is denser than vinegar. Oil is made up of nonpolar molecules that are typically less dense than water, while vinegar is a mixture of water and acetic acid which has a higher density than oil.
How the nonpolar character of oil molecules helps when removing oil from water?
Oil molecules are nonpolar, so they will not mix with polar water molecules. This characteristic helps when removing oil from water using nets and floating barriers is that oil molecules won't mix with water molecules and the oil molecules float. Because oil floats on water, the oil can be skimmed off the top of the water.
What happens if oil and water are mixed together without an emulsifier?
Water is denser than oil because particles in the oil are more separated between each other than in water. This results in oil rising to the top, while water stays at the bottom of the recipient.
Is a heterogeneous mixture oil and vinegar air vinegar in water sugar water?
Yes, a heterogeneous mixture is one in which the components are not uniformly distributed, like oil and vinegar. An example of a heterogeneous mixture is oil and vinegar salad dressing. Another example is sand and water, where the sand particles do not dissolve in the water.
Why oil molecules are not attracted to the water molecules in vinegar?
Oil molecules are nonpolar, meaning they do not have charged regions, while water molecules are polar, having a positive and negative side due to their molecular structure. This difference in polarity leads to a lack of attraction between oil and water molecules. In vinegar, which contains water and acetic acid, the polar water molecules are more attracted to each other than to the nonpolar oil molecules, resulting in the two substances not mixing. Consequently, oil and vinegar tend to separate when combined.
What is the relationship between oil and water?
The relationship is that they do not mix. The molecules in water are attracted to each other and will not mix with the oil molecules which are also attracted to each other and therefore will not mix with the water molecules
Do water molecules attract nonpolar molecules such as oil?

What are some interesting facts about oil?
Water molecules won't form a solution (are not miscible) in oil. The reason is that water molecules are polar, and oil molecules are not. Water molecules, in an environment of oil, are attracted to each other, and this polar bonding excludes the oil molecules.
did the oil dissolve in water?
Oils are hydrophobic, or “water fearing.” Instead of being attracted to water molecules, oil molecules are repelled by them. As a result, when you add oil to a cup of water the two don't mix with each other.
Why does food colouring go through oil and dissolves in water?
Food coloring is made up of water-soluble molecules that are attracted to water. When food coloring is added to water, the molecules disperse evenly throughout the water. However, when food coloring is added to oil, the water-soluble molecules are not attracted to the oil and do not dissolve in it.
Is oil denser than of vinegar?
Yes, oil is denser than vinegar. Oil is made up of nonpolar molecules that are typically less dense than water, while vinegar is a mixture of water and acetic acid which has a higher density than oil.
How the nonpolar character of oil molecules helps when removing oil from water?

Because oil floats on water, the oil can be skimmed off the top of the water.
What happens when you pour red wine vinegar and olive oil into a cup?
They will separate: olive oil on top, red wine vinegar on the bottom. The oil is non-polar and the vinegar (which is mostly water) is polar.
Does water dissolve into all solutes?
No, water does not dissolve into all solutes. Some solutes, such as nonpolar molecules like oil, do not dissolve in water because they are not attracted to the polar water molecules.
What happens if oil and water are mixed together without an emulsifier?
Water is denser than oil because particles in the oil are more separated between each other than in water. This results in oil rising to the top, while water stays at the bottom of the recipient.
Water and nonpolar molecules do not easliy mix?
Water is a polar molecule with positive and negative charges that attract other polar molecules but repel nonpolar molecules. Nonpolar molecules lack charged regions, so they are not attracted to water and tend to cluster together instead of dissolving in water. This is why oil, for example, does not mix with water.
