  • For Savannah: I also found the periodic tables and your cheat sheet from chem 20′s final, so I can give these to you sometime or try and remember to leave them for someone to pick up tomorrow if you’re not here

> Sept. 3 – Friday, Day 5

  • Reviewed textbook questions and completed new review assignment up to 8 part (a), don’t worry about part (b) and (c) of question 8.
  • IMPORTANT: Tuesday we’ll have a “Review Test” based on the first review handout, it will be formatted in a similar way to it so expect similar questions to it, the most important questions you need to understand are the stoichiometry ones like question 24 and 25, and practice others like those that were in the textbook and the new handout ALSO, remember how to operate with molarity units as well (M = mol/L) and you MUST memorize that molar mass (determined by the periodic table) is in the units g/mol — you will be able to use your periodic table and your cheat sheet for the review test
  • HELP ME! :: if you need help, I’ll be ready to help at the school at 10:00 am Monday morning and I’ll meet you at the doors of the school because they’ll be locked otherwise (so just come on time), bonus marks for you if you bring treats!! (just jokes)

  • Notes about the review handout:
  1. the answer to question 7 is 0.27g of liquid petroleum gas, (which rounds up to 0.3 g, because of 1 sig. fig)
  2. Question 2a of the Explanation Questions and Equations doesn’t actually cause CuCl2 to precipitate, this is because the Cu+1 ion would precipitate but this is the Cu+2 ion, so this is a soluble product and therefore aqueous, so only the BaSO4 precipitates, sorry about that!
