Answer 1

A mixture consisting of tiny particles that are intermediate in size between those in solutions and those in suspensions and that are suspended in a liquid, solid, or gas.

Question 2

Emulsion

Answer 2

Any mixture of two or more immiscible liquids in which one liquid is dispersed in the other.

Question 3

Solution

Answer 3

A homogeneous mixture of two or more substances uniformly dispersed throughout a single phase.

Question 4

Solute

Answer 4

The substance that dissolves in the solvent.

Question 5

Solvent

Answer 5

The substance in which the solute dissolves.

Question 6

Alloy

Answer 6

A solid or liquid mixture of two or more metals.

Question 7

Heterogenous Mixture

Answer 7

A mixture where the substances aren’t mixed uniformly and are not evenly distributed.

Question 8

Decanting

Answer 8

The process of pouring a lighter liquid off of a heavier liquid.

The scattering of light.

Question 11

Polar Compound

Answer 11

A molecule that has an uneven distribution of electrons.

Question 12
