Part I
1. density, speed, etc
2. mass, volume, et
3. rust, corrosive
4. chemical is about grouping not how many groups
5. 2 or more elements chemically combined in a fixed mass ratio
6. separation technique, charateristics, composition
7. homogeneous mixture only needs to be uniform through a single container not between container whereas cpds are constant in both.
8. Applied
9. Hypothesis
10. Controlled
11. Laws are theories that have been greatly testing including in all places. Law just states but theory states and tells why.
12. permanent color change, temp change, precipitate formed, and gas formed (odor).
13. precipitate
14. Law of Conservation of Mass, Energy, Kinetic Molecular (KMT), and Coulombic force
15. All substance are composed of particles that are in constant motion and sometimes interact.
