What is a technique that can be used to separate molecules in a mixture by subjecting them to an electrical field within a gel?
Gel electrophoresis is a technique that can be used to separate molecules in a mixture by subjecting them to an electrical field within a gel matrix. The molecules move through the gel at different rates based on their size and charge, allowing for their separation and analysis.
Does a mixture contain molecules?
Yes, a mixture contains different molecules of substances that are combined physically but do not chemically bond with each other. These molecules retain their individual properties within the mixture.
Can physical method be used to separate molecules in crude oil?
Yes. Oil is a mixture so physical methods are appropriate. Fractional distillation is the physical process used in oil refineries to separate the oil into different, saleable parts.
What are two ways in which mixtures are different from compound?
- A mixture contain two or more compounds.- A mixture can be separated by physical procedures.
How can we determine that water is a compound not a mixture?
Water is a compound because its molecules are formed of chemically combined elements (hydrogen and oxygen) in a fixed proportion. A mixture is a combination of separate atoms, molecules, or particles that are not chemically bonded or in any fixed proportion.
If you have a mixture of substances with different - sized molecules. How could you separate them?
One way to separate substances with different-sized molecules is through a process called chromatography, where the mixture is passed through a material that selectively interacts with the molecules based on their size. Another method is fractional distillation, where the mixture is heated to separate the components based on their boiling points. Size exclusion chromatography is also effective, as it separates molecules based on their size by allowing smaller molecules to travel through the column more slowly than larger ones.

How does distillation work to separate different components in a mixture?
Distillation works by heating a mixture to separate its components based on their different boiling points. As the mixture is heated, the component with the lowest boiling point vaporizes first, rises, and then condenses back into a liquid in a separate container. This process allows for the separation of different components in the mixture.
What does heterogeneous mixture?
A heterogeneous mixture is made of different substances that remain physically separate.
Does a mixture contain molecules?
Yes, a mixture contains different molecules of substances that are combined physically but do not chemically bond with each other. These molecules retain their individual properties within the mixture.
Can physical method be used to separate molecules in crude oil?
Yes. Oil is a mixture so physical methods are appropriate. Fractional distillation is the physical process used in oil refineries to separate the oil into different, saleable parts.
Is oil an element a mixture or a compound?
Oil is a mixture because it is composed of different types of molecules such as hydrocarbons, fats, and lipids. These molecules are not chemically bound to each other, making oil a mixture.
What are two ways in which mixtures are different from compound?
- A mixture contain two or more compounds.- A mixture can be separated by physical procedures.
How is pure compound different from mixture?
A compound is a simple substance, a mixture is formed from two or more compounds.A mixture can be separated by physical procedures, a compound not.
How do you separate a liquid mixture of three different substances when it changes to a solid at different temperature?

What can be used to separate parts of a mixture?
If the mixture is a mixture of solids and if one of constituent is a ferromagnetic substance, a magnet can be used to separate the magnetic and non-magnetic substances. If one of the constituent is a sublimate, sublimation can be used. If the mixture is a mixture of solids and liquids, decantation, filtration and distillation can be used. If the mixture is a mixture of liquids, fractional distillation can be used to separate the different constituents taking advantage of the difference in boiling points of the different constituents.
What technique can be used to separate a mixture in science?
One technique that can be used to separate a mixture is chromatography. In chromatography, the components of the mixture are separated based on their different affinities for a stationary phase and a mobile phase, allowing them to move at different rates and be identified.
