Chemistry 12:  We started with a minireview of Buffers, then we took notes on Metal and Non-Metal Oxides.  After high fiving our partner for finishing the Acid Base unit, we read 4.21 and did the Acid Base Practice Test.  In the last 15 minutes we started the electrochemistry Unit by making an electrochemical cell that can produce 0.85 V.  Test on Tuesday.  Sort out your problems by Friday - I will be away on Tuesday and Wednesday.

Chemistry 11:  After going over the green WS on the Solubility of NaCl, we reviewed the shapes and bond angles in some molecular compounds.  We learned how to write dissolving reactions, and we also learned how to find the concentration of each ion in solutions.  The WS called "The Concentration of Ions in Solution " is due on Friday.  In the second half, we wrote the TRU Chemistry 11 contest.
