ANSWER:

1. A mixture is a material composed of two or more simpler substances in chemistry.

2. There are two types of mixtures: heterogeneous and homogeneous. Heterogeneous mixtures have visually distinguishable components, while homogeneous mixtures appear uniform throughout. The most common type of homogenous mixture is a solution, which can be a solid, liquid, or gas.

3. Homogeneous:

1. kool-aid

2. salt water

3. air

4. coffe

5. whiskey

Heterogeneous:

1. chocolate chip cookie

2. soup

3. earth

4. cookie dough ice cream

5. trail mix

4. (a) The term saturated solution is used in chemistry to define a solution in which no more solvent can be dissolved. It is understood that saturation of the solution has been achieved when any additional substance that is added results in a solid precipitate or is let off as a gas.

Eg: Saltwater

(b) Pure substance: A material that is composed of only one type of particle.

Eg: Gold, oxygen and water.

(c) Colloid: A homogeneous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance.

Eg: Gels, sols and emulsions.

d) Suspension: A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase sometime after their introduction. We apply the word suspension when particles are big enough to eventually settle.

Eg: wheat flour and water.
