What is locating agent used for?
Locating agent is a substance/liquid that help to separate and analyze colorless substances in chromatography by reacting with the colorless substance to form colored spots on the chromatogram.
Which term is given to a substance that can not separate into less complex substance by chemical means?
an element
Hyow do you separate 2 substances in a mixture if they both can both be dissolved in water?
One way to separate two substances in a mixture if they are both soluble in water is by using a process called fractional crystallization. This involves selectively precipitating one substance out of the solution by altering the temperature or concentration, allowing the other substance to remain in the solution. The precipitated substance can then be filtered out, leaving the remaining substance dissolved in the solution.
How does chromatography separate molecules?
The principle is based on equilibrium of the molecules between the mobile phase and the stationary phase. This will vary depending on the polarity of the substance, and the two phases. If the substance in more soluble in the mobile phase, it will travel further, and vice versa.
Can sublimation of a substance be utilized to separate it from other substances?
Yes, it is possible if one of the substance will sublime and others will not.
Can natural be invisible?
Air is natural and it is invisible. Yes, it is possible for a natural substance to be invisible, although it rarely happens.

Heating a white substance produces a vapor and black material Was the substance an element or a compound?
compound as it decomposed into two separate things.
Two or more ingredients mixed together where one ingredient dissolves into the other becoming nearly invisible and it is hard to separate?
A solution or an emulsion.
Is dough reversible?
No. Once water and flour are mixed, there is no way to separate the two since they form a completely new substance.
What type of mixture has one substance present and two phases present?
A heterogeneous mixture with one substance present and two phases present is a suspension. In a suspension, the particles of one substance are physically mixed in another substance but are not dissolved, resulting in two separate phases. Examples include sand in water or oil in water.
How can you use water to separate two substance like carbon n sodium chloride?
Sodium chloride is soluble in water and carbon not.
How do you separate a soluble substance from another?
Filter it??
Which term is given to a substance that can not separate into less complex substance by chemical means?
an element
How is air descirbed?
The invisible gaseous substance surrounding the earth, a mixture mainly of oxygen and nitrogen :)
How could you use a difference in melting point (freezing point) to separate a solution of two liquids?
Cool it until one substance freezes out.
