Today we spent some time getting to know some of the major polyatomic ions. We also took time figure out how to use the polyatomic ions in terms of naming molecules. With that out of the way, we now have learned the alphabet (the periodic table) and how to make words with it (making molecules). This brings us to creating sentences with our words, in other words, chemical equations. We took a look at the different parts of a chemical equation and began to work a bit on balancing them.
For homework this week,
Do the exercises in the enclosed .pdf. I've included the answers as well.
I would HIGHLY recommend taking another look at the naming worksheet I had you do for homework a while back. Quite a few of you did poorly on that part of the last exam.
MAKE SURE if you get something wrong you know EXACTLY why it's wrong. Sorry for all the caps and the bold but I get the feeling folks are just doing the problems, checking their answers and moving on. That's a No No! If you get it wrong, you really need to know why. Otherwise it's going to come along on a test and get'ya. If you get a problem wrong on the homework, REDO IT FROM SCRATCH. Do Not Assume you know how to do it from just looking at the answer. It took me until college to figure this out. I'm handing this piece of advice to you for no extra charge. Take advantage of it. :)
