So, when we came into fifth period, Mrs. Friedmann checked in our homework.  She also said not to worry if we didn't understand the two redox equations that were homework because they were complicated.  The answers to them were...

      a. Na2Cr2O7 + 2HNO3 + 7H2O2 -> 2H3CrO8 + 2NaNO3 + 5H2O

      b. 3K2MnO4 + 4HNO3 -> 2KMnO4 + MnO2 + 4KNO3 + 2H2O


We also went over the homework on page two in the packet.  Then, we completed page 4 in the same packet.  I am pretty sure that Mrs. Friedmann will put these notes on moodle.


Finally, our homework is problems d and e on page 3 in the same packet.  Also, there is a webassign due tonight.  There are also two webassigns due tomorrow night.  One of these (called Redox equations) is for extra points that can be added on to our test.  Don't forget to add some easy points onto your grade!!
