4. What conditions require you (i.e. when do you need) to perform a limiting reactant calculation? __________________________
5. What do you call a gas particle that when it is at room temperature, it is in the liquid phase? ___________________
6. What does a liquid particle need to do to get into the gas phase (become a gas particle)?
___________________________________________________________________________
7. What is the two differences between a boiling and evaporation (Choose either one as a basis to explain difference).
a. _________________________________________
b. __________________________________________
8. Write the symbol for a polar bond, _____________ and write down how you have memorized the direction of the symbol
______________________________________________________________________________
9. What are the cut-offs of deltaEN for ionic bonds ______________,
polar bond ______________, non-polar bond _____________
10. When two metal atom get close enough for their valence electrons interact, do the atoms give/take, share or both give away their valence electron? Circle correct answer. Explain what you get after to create metallic bond.
11. What is the phrase Mr. McLeod makes you memorize to help remember the type of molecular polarity of a compound/polyatomic ion?
12. List the species (e.g. ionic, metallic, polar, etc) from highest IMF to lowest IMF
____________________________________________
12. Which one of the following has the highest IMF and why (explain noting IMF of each in space below), H2O , CH4 or C1O1.
13. What does VSEPR stand for? To determine shape/geometry of covalently bonded substance, VSEPR uses how many electron domains around central atom. What are the two types of domains that you added up to get the total number of domains?
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)? (For 2018-2019 students including CP, there are no in-depth explanation or showing a diagram).
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)? Yes or No? Explain.
16. For the following, determine and write the letter of the type of species ( A - acid, MC - molecular, IC - ionic ) it is and then determine the chemical name or chemical formula.
a. Iron (III) oxide
b. HCl
c. Dinitrogen hexaflouride
