Sand would lay on the bottom, water would occupy the middle, and oil would float on the top. So, in a tall tube of all three substances, careful extraction from three heights of the tube would separate as required.

Is blood a substances or a mixture?
Blood is a mixture of substances minly containing RBC (red blood cells or erythrocytes),WBC(white blood cells)and thrombocytes. The suffix -CYTES means cells. all of these substances in addition to other substances are present in the serum which is the fluid part of the blood. when blood is collected in a test tube using a sterile needle and it is allowed to stay the RBC's clot along with the thrombocytes and they settle down leaving the serum on top.
What is explosive mixture?
A mixture of substances that may explode under the right circumstances. Powdered flour dispersed thru air will explode if a spark is present. Gunpowder is an explosive mixture, not a compound. Nitroglycerine is NOT an explosive mixture. It is an explosive compound.
What are three ways to separate substances in a mixture?
Three ways would be Liquid liquid - distillation (separation based on boiling points) Column chromatography separates solids dissolved in eluent based on polarity Filtration (washing with a solvent that dissolves one compound and not another)
What are four types of mixtures?
Mixtures are substances that are made by physical combination of one or more substances and none of the constituent elements are changed. The basic classification of mixtures is into homogeneous and heterogeneous substances. They can also be further divided under these two categories in to solutions, dispersions or colloids.Air is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances. Salt, sugar, and many other substances dissolve in water to form homogeneous mixtures. A homogeneous mixture in which there is both a solute and solvent present is also a solution. Heterogeneous mixtures include fine sand or silt in water.Rate This Answer
What is the substance present in large amount in a mixture?
solvent or salutations
What type of mixture has one substance present and two phases present?
Pure substances.
What are two characteristics that distinguish compounds from mixture?
Compounds are pure substances composed of atoms bonded together chemically in definite proportions. Mixtures are not pure substances and the components of a mixture are not chemically bonded and can be present in many different proportions.
Do the substances in a mixture be mixed in any proportion?
Substances in a mixture can be present in any amount. In a mixture, substances are only mixed physically and retain their chemical identity.
What are the chemicals that are present in the mixture of ethanol and water?
Of course, these substances are ethanol and water.

Air is a mixture of nitrogen oxygen co2 noble gases and water vapours
Consider a mixture of water sand and oil.how many pahese are present?

Can a mixture be defined by chemical formula?
Not by a single one. You can have the individual compounds making up the mixture be present in a stoichiometric ratio, of course, though you don't have to.
