Today, we got our Aqueous Reactions Test returned to us... or was that yesterday? I don't remember. Either way, the answers for the said test is posted up here; uploaded via slideshare.
We did some work on Oxidation and Reduction by going over pages 18 to 21 in the Aqueous Reactions Unit booklet. Remember that oxidation is the loss of electrons, and reduction is the gain of electrons and that the exchanging of electrons in a redox reactions occur simultaneously.
We went over the rules for assigning Oxidation Numbers. Note that the diatomic elements H2O2F2Br2I2N2Cl2 and pure elements have an oxidation number of zero. Also consider that the sum of the oxidation numbers in any neutral molecule is zero and that the sum in any ion is equal to the charge on the ion.
We were told to do questions 1 to 3, on the given practice worksheet "Assigning Oxidation Numbers". Also, Ms. Kozoriz swore by accident today. Just putting it out there.
Our next scribe will be the lovely Bernadette! :D
