Class Blog October 30th, 2013

What we did in class

  1. Went over answer key for worksheet ChemThink LabsSim Questions - Precipitates (Look at key in the moodle units 4 key f
  2. Mrs. F showed us different examples of equations: 
    • We will use molecular and net ionic equation the most in this class
  3. Aqueous means it is a solution that contains water
  4. We talked about good blogging ideas:  
    • Lets step up our game period 4, and beat period 5 in blogging! (Don't worry, it's not like Mrs. Friedmann is comparing us to them or anything..)
    • Your name should be labeled "Q2Kate M.". Q2 for quarter two and then your name with last initial.  
    • Also, make sure you check the blog every day. The blogger will make sure it is posted by at latest 10pm that night.  Everyone needs to try to comment every night between 10-10:30pm saying something you like, don't like, or something you are confused on. 
  5. We performed the Double Replacement Reactions and Solubility Lab  in the last 15min of class. There is no lab write up for this but, there are questions that need to be answered by tomorrow for homework. Read the lab directions and look at results below. NR=no reaction PPT=precipitation reaction.
  6. Homework for tonight: 
    • Complete Post Lab Questions #1-6. Due tomorrow.
    • Post lab question #1 changes: "write the name and formula with possibilities for the solid product" 
    • Post lab question #2 changes: choose 8 and write the balanced molecular equation ONLY
