What is the reason hydrocarbons are not soluble in water?

Hydrocarbons are not soluble in water because they are hydrophobic. The term hydrophobic means “water fearing” and hydrophobic molecules do…

Why hydrocarbons are not soluble in water?

Because the difference between the electronegativities of carbon and hydrogen is small (EN = 0.40), hydrocarbons are nonpolar. As a result, they do not dissolve in polar solvents such as water. Hydrocarbons are therefore described as immiscible (literally, “not mixable”) in water.

How long does it take for flour and water to harden?

Flour and water takes a but longer to dry than glue, but after about 12 hours it should be dry.

What are 5 examples of suspensions?

Common examples of suspensions include:

  • Mud or muddy water: where soil, clay, or silt particles are suspended in water.
  • Flour suspended in water.
  • Kimchi suspended on vinegar.
  • Chalk suspended in water.
  • Sand suspended in water.

Is salt and water mixture a suspension?

Although Most Salt are soluble in water (Properties of Ionic Compound) , Not all are soluble ,which means mixing a salt and water can produce either a Solution (homogeneous mixture) or a Suspension (heterogeneous mixture).

Why oil and water is non uniform?

Oil and water do not mix, instead forming two distinct layers called phases. The oil phase is less dense than the water phase and so the oil floats on top of the water. In the vegetable soup example, one phase would be the liquid soup itself.

Is water uniform or nonuniform?

So, while pure water will appear uniform, or homogeneous, bodies of water out in nature will likely contain particles and be nonuniform, or heterogeneous, in appearance.

What is the difference between uniform and non-uniform mixtures?

The difference between uniform and non-uniform mixtures is the degree at which the materials are mixed and the sameness of their composition throughout the mixture. Another word for a uniform mixture is a homogeneous mixture. Homogeneous mixtures have the same composition throughout (home = the same).

Is vinegar and water uniform or non-uniform?

Answer. Answer: Vinegar and water are non visible, uniform(homogenous).

Which one is an example of non-uniform mixture?

Particles are not uniformly distributed in a heterogeneous mixture. Examples include chocolate chip cookies, soda with ice, a sandwich, pizza, and tossed salad. A heterogeneous mixture is defined as a mixture that has a non-uniform composition. In other words, its composition varies from one location to another.
