Answer 1

2. A compound (has two+ types of matter)

3. Homogeneous (dissolves in another substance)

4. Heterogeneous mixture

5. Element?

6. Physical?

7. a. physical b. chemical

Answer 2

A mixture is composed of two or more types of matter that can be present in varying amounts.

A solution is a homogeneous mixture.

A mixture that is not uniform throughout is a heterogeneous mixture.

A pure substance that cannot be broken down chemically is an element.

A characteristic of matter that’s not associated with a change in its chemical composition is known as a physical property.

Wax melting is an example of a physical change in the state of matter.

A banana peel turning brown is an example of a chemical change in the state of matter.

Answers:

2. A mixture

3. a homogeneous

4. a heterogeneous

5. an element

6 & 7. a physical

8. a chemical

Step-by-step explanation:

Mixtures can be further classified as homogeneous and heterogeneous mixtures based on the types of combining elements.

• Homogeneous mixtures are also termed as solution as they look uniform throughout the solution.
• Heterogeneous mixture is composed of different concentration of solute and solvent and it do not look uniform throughout the mixture.

The physical changes occur on the object without changing its chemical properties like wax melting. While chemical changes occur due to oxidation or reduction or any other kind of reaction with the surface of matter.
