7. Which one of the following has the highest IMF and why (explain in space below), H2O , CH3CH2OH, or NH3.
8. A Limiting Reactant problem calculation is a lot of work, so when is the only time you need to performs this type of calculation?
9. What is the Limiting reactant and why is important in a stoichiometry calculation to know it?
10. What does "stoichiometric amounts" mean?
9. 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?
11. 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)?
12. 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.
13. 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).
