_________ is the mechanical separation of a mixture based upon the sizes of the mixtures components.

Answers

Answer 1

Answer:

Sieving

Explanation:

Sieving is a mechanical separation technique which depends on the relative sizes of particles in the mixture.

A mesh is used to discriminate between particle sizes. Particles in the mixture which are larger than the mesh size do not pass through the sieve, hence particles whose size is less than that of the mesh are separated from the rest of the particles in the mixture.

How can you test to see if a substance is soluble or insoluble? 1 Place the substance in water. 2 Put the substance under sunlight. 3 Heat the substance up. 4 Put the substance in a freezer.

Answers

You can test whether a substance is soluble by heating the substance up.

How does solubility in water work?

Solubility is the property that a substance has to be able to dissolve in another that can be called a solvent. Whether a substance is polar or nonpolar depends a lot on the solubility of the substance since with this the substance is more or less soluble. The more polar a substance is because of its functional groups, the more soluble it will be.

Solubility is determined by the intermolecular forces that exist between the solvent and the solute and not all substances will be able to dissolve in others, such as oil cannot dissolve in water

A good way to know if the solute dissolves is by heating the solution, so the substance that dissolves is the solute and the one that remains will be the solvent.

Therefore, we can confirm that you can test whether a substance is soluble by heating the substance up.

What behavior do all liquid
or plastic solids near a
heat source exhibit?
L

Answers

Answer:

Explanation:

One of the properties of a liquid is that, it's particles move freely (not tightly packed) hence the reason for it's free flowing (no definite shape) when shaken in a container, unlike a solid whose particles are tightly packed with restricted/no movement and hence the reason for it's compactness and it's definite shape.

When a plastic solid (whose particle is tightly packed and have a restricted movement/no movement) is placed near a heat source, it's particles gains energy in the process and starts to move (though slightly free) and become less tightly packed hence the reason it is observed that plastic solids near a heat source melts.

From the above, it can be deduced that a liquid and a plastic solid near a heat source have there particles move freely (and not tightly packed) hence making the two substances flow freely with no definite shape.
