--Went over homework (Keys are posted on moodle)

--We were assigned partners, exchanged phone numbers, and were assigned a take-home quiz that we will do with our partners tonight

--Did the Copper and Silver Nitrate lab

Lab Data:

SIlver Nitrate: 1.44g

Copper Wire: 0.73g

Mass of 100 mL beaker: 50.15g

Final Mass: 0.72g

Change of Copper Weight: 0.01g

Homework:

1) You have been assigned a partner to work with to complete Stoich Quiz #2 for homework (posted in the Unit 2 Handouts folder).  If you cannot meet with your partner in person, call them and do the quiz via phone meeting; you should have exchanged phone numbers in class today.  Plan on taking about 15 minutes together.  Follow the directions on the quiz and work as "expert" and "editor".  Due tomorrow.

2) The "Copper and Silver Nitrate" prelab was due in class today.  Check your answers against the key that is posted in the Unit 3 Keys folder.  THEN write 1-2 sentences in your journal that summarize what we are trying to accomplish with this lab.  WHAT ARE WE GOING TO CALCULATE WITH OUR LAB DATA?  Due tomorrow.

3) The "Copper and Solver Nitrate" lab write-up will be due on Monday, October 21.  If you were absent today, get data from the blog post and use that to complete the write-up.

4) Just a heads-up -- our unit 3 test is one week from today, next Wednesday, 10/23.
