2. a homogeneous mixture with particles so small they cannot be seen without a microscope is a(n) solution.
3. a(n) suspension is a liquid heterogeneous mixture in which visible particles settle.
4. a(n) compound is a material made from two or more combined elements.
5. if all the atoms in a sample of matter are alike, that kind of matter is a(n) element.
6. a(n) homogeneous mixture has two or more substances blended evenly throughout.
7. the scattering of light by colloids and suspensions is called the tyndall effect.
8. size, shape, and melting point are physical properties.
9. a burnt object has undergone a chemical change.
10. the law of conservation of mass states that mass is not gained or lost during chemical changes.

Explanation:

1. A heterogeneous mixture has distinguishable different materials.
2. A solution is a homogeneous mixture with microscopic - sized particles.
3. A suspension is a liquid heterogeneous mixture with settling visible particles.
4. A compound is made of two or more combined elements.
5. An element has identical atoms in a sample of matter.
6. A homogeneous mixture has uniformly - blended substances.
7. The Tyndall effect is light - scattering by colloids and suspensions.
