5. Define compound: ____________________________________________ |
1. All substances (or particles or "things") have 2 characteristic (made up of): |
________________________________________________________________ 15. Define Kinetic Molecular Theory (KMT): ___________________________________________________________ |
2. Define Kinetic Molecular Theory (KMT) also called Particle view of Matter: |
_________________________________________________________________________ 16. _____________ is the symbol for base unit of mass. |
3. State define the two Conservation laws that comes from KMT: a) b) 4) What law says that same charge particle's REPEL, and difference charge particles ATTRACT? 5) When two particles collide, what are the two possible outcomes and what kind of "change" do we call it. 6) Atoms are one of the "basic unit" or particles. Draw a picture of the atom and locate each subatomic particle and label the items. 7) From Bohr's model of atom, if a valence electron is in a lower energy level, does it have more or less energy than a valence electron in a higher energy level. Also does it the lower energy level electron have a greater or less Coulombic force to nucleus than the one in the higher energy level? 8) Metals tend to do what with their valence electrons? 9) Non-metals tend to do what with their valence electrons? 10) What is the difference between Intramolecular force and Intermolecular forces. What are the name of the three different types of Intramolecular forces followed by what types of elements are interacting. 11) On the back of this paper (or separate sheet of paper), explain what happens when a metal and non-metal elements get close enough to interact (with respect to valence electrons), the name of that kind of bond, name the type of compound, and draw a picture of this substance. Also explain what is going on with the valence electron of each atom. 12) On the back of this paper (or separate sheet of paper), do the same as Question 11 except it is two non-metals elements involved. 13) On the back of this paper (or separate sheet of paper), explain what happens when two metal elements get close enough to interact (with respect to valence electrons), the name of that kind of bond and draw a picture (please label the parts)? 14) What is the difference (looking at electrons) between a Polar molecule and a Non-polar molecule? 15) Define activation energy: 16) What is the other requirement for an Effective collision? 17) ____________________ explains how "fast" products can be made (also called Rate of Reaction) in a chemical reaction. 18) What is the difference between a Reversible reaction and an Irreversible reactions. 19) Exothermic reaction/process absorbs energy for the reaction to occur. True / False 20) What two pieces of information does a quantitative measure provide if one is following the rules of Significant figures (Sig fig)? 21) _________________ is has to do with the mechanics or way in which you make a quantitative measurement. 22) _____________ is the symbol for base unit of mass. |
23) Give me a piece of lab safety equipment, explain its function and explain where it is in the room. |
