1. Print out a copy of [http://www.tmcleod.org/Level1/0708MolecularGeometryWorksheet.doc Worksheet for Molecular Geometry] and fill in the appropriate information for N1H3, P1F5, F2,S1O2

2. Print out a copy of [http://www.tmcleod.org/Level1/0708MolecularPolarityWorksheet.doc Worksheet for Molecular Polarity] and complete the table for the following: 1) CCl4 2) <nowiki>BeCl</nowiki>2 3)CS2 4) NF3 
 
 
3. What is the hybridization of <nowiki>PCl</nowiki>5, ____________________ 
 
 
4. If you replaced P (phosphorus) with N (nitrogen) in the above compound, can the compound exist and why? (Hint: subenergy levels)? 
 
 
 
5. Write the symbol for a polar bond, _____________ and write down how you have memorized the direction of the symbol 
 
______________________________________________________________________________ 
 
 
 
6. What are the cut-offs of <nowiki>deltaEN</nowiki> for ionic bonds ______________, 
 
polar bond ______________, non-polar bond _____________ 
 
 
7. What is the phrase Mr. <nowiki>McLeod</nowiki> makes you memorize to help remember the type of molecular polarity of a compound/polyatomic ion? 
 
 
 
 
8. List the species (e.g. ionic, metallic, polar, etc) from highest IMF to lowest IMF

____________________________________________ 
 
 
 
9. Which one of the following has the highest IMF and why (explain in space below), H2O , CH3CH2OH, or NH3. 
 
 
 
 
10. A Limiting Reactant problem calculation is a lot of work, so when is the only time you need to performs this type of calculation? 
 
 
11. What is the Limiting reactant and why is important in a stoichiometry calculation to know it? 
 
 
12. What does "stoichiometric amounts" mean? 
 
 
13. Crude oil is a mixtures of compounds. Two of these compounds are hexane (C6H14) and octane (C8H18). What is the physical process called that separates these two liquid? What property is this physical process based on? Both of these substance have _________________ IMF. Which one has the higher IMF and why? Which one boils first? 
 
 
 
 
 
 
 
 
14. Using your knowledge of IMF, explain why vegetable oil and water do not mix or do not dissolve in each other. Is that the correct words to use with these two substance? If not, what are/is the correct word(s)? 
 
 
 
 
 
 
 
15. Substance A has a greater IMF than Substance B, would it "make sense" (from knowledge of IMF) that Substance A is a gas whereas Substance B is a liquid (both substance are at the same temperature)? Explain. 
 
 
 
 
 
 
 
 
16. Using your knowledge of "metallic bonds" and "ionic bonds", explain in words and draw a picture of why metals are malleable and ionic compounds are not malleable (called brittle). 
 
 
 
 
 
 
 
 
 
 
 
 
17. I reacted 43.1 grams H1Cl1 (Hydrochloric acid) with excess oxygen gas via the following chemical reaction: 
4 H1Cl1 (g)+ 1 O2 (g) --> 2 Cl2 (g) + 2 H2O1 (g) 
 
If I experimentally produced 36.1g Cl2, what is the stoichiometric yield and percent yield of Cl2?
