Question 1

Colloid

Answer 1

Mixture with little particles that are in between the size of particles in solutions and those in suspensions that suspend in liquids, solids, or gases.

Question 2

Emulsion

Answer 2

Mixture between at least two immiscible substances where one liquid is mixed in the other.

Question 3

Solution

Answer 3

Homogeneous mixture of at least two substances that are uniformly mixed.

Question 4

Solute

Answer 4

The substance that is dissolved into the solvent.

Question 5

Solvent

Answer 5

The substance where the solute is dissolved.

Question 6

Alloy

Answer 6
