| 3. |
a mixture containing particles that settle out if left undisturbed |
| 5. |
sharing of electrons by atoms so that all atoms involved achieve a filled valence level. |
| 8. |
the temperature at which the EVP is equal to standard atmospheric pressure |
| 9. |
diffusion through a tiny opening |
| 12. |
biological catalysts that speed up the rate of reactions in the body |
| 13. |
a description of an element's tendency to undergo chemical reactions. |
| 16. |
equation shows only those reactants and products that are the new materials formed from the chemical reaction |
| 17. |
transfer of electrons between atoms, resulting in cations and anions |
| 18. |
change in heat of the products from the reactantsCatalyst- a substance speeds up a chemical reaction without itself undergoing any chemical change. |
| 19. |
atoms will gain, lose, or share valence e- to attain a 8 valence electrons |

| 1. |
the random movement of gas molecules from an area of higher concentration to an area of lower concentration |
| 2. |
microscopic particles are dispersed evenly in another substance |
| 4. |
the amount of heat/energy to 1 gram of a substance by 1 degrees C. |
| 6. |
transition of a substance directly from solid to gas |
| 7. |
the temperature and pressure at which the solid, liquid, and gas forms of a substance coexist. |
| 10. |
the total amount of energy; movement |
| 11. |
transition of a substance directly from gas to solid |
| 14. |
a measure of how strongly atoms attract bonding e- to themselves. The higher the number, the greater the attraction for e-. |
| 15. |
point- the point on a phase diagram in which two phases of a substance become indistinguishable from each other, a supercritical fluid. Supercritical fluids have the characteristics of both liquids and gases. |
