Explanation:

1. Homogeneous mixtures have uniform composition.
2. Matter is anything that has mass and occupies space.
3. An element is a pure - substance made of only one type of atom and cannot be broken down into simpler substances.
4. Extensive properties depend on the amount of matter present.
5. Solids have a definite volume and a definite shape.
6. Intensive properties do not depend on the amount of matter present.
7. Gases have neither a definite shape nor a definite volume.
8. Physical properties can be observed or measured without changing the identity of the substance.
9. Products are substances formed by chemical changes.
10. Chemical properties relate to a substance's ability to undergo changes that transform it into different substances.
11. A mixture is a combination of two or more substances, each retaining its own individual properties.
12. Water freezing to ice is a physical change as it is a phase - change and the chemical identity of water remains the same.
13. A soda is a homogeneous mixture as it has a uniform composition throughout.
14. Density is a measure of how much mass occupies a certain volume.
15. Rusting of a bicycle is a chemical change as new substances (iron oxides) are formed.
16. Blood is a heterogeneous mixture as it has different components that are not uniformly distributed.
17. The Law of Conservation of Mass states that matter cannot be created or destroyed by a chemical change.
