Eventhough most of you weren’t in class, I didn’t want you to miss out. Here’s the rundown:
HW #12: pg 870 #56, 59-60, 63-64, 67-68
Be sure to have read over and know your lab for Friday.
You will also be responsible for the concepts in the remainder of Chapter 17. Specifically pay attention to corrosion of iron and how to prevent it, how an electrolytic cell is different from a voltaic cell, how electrolytic cells are used commercially, and other types of cells. We will try to finish up Chapter 17 on Tuesday and review what we can. Our test over Chapter 17 will be Thursday, Nov 8.
Check out these sites to help you understand Chapter 17!

Getting back into gear with stoichiometry can be challenging. In HW #3, you are asked to predict amounts of products based on amounts of reactants or amounts of reactants based on amounts of products. None of these problems will involved limiting reactants just yet. We will get to that later this week. To get started with basic reaction stoichiometry, follow these simple steps:
If you need some examples, check out this site from Purdue Chemistry Education.
A few students have asked, “What do you mean by the term liquid?” The Chemistry I Density Bottle Project requires at least four different liquid layers. I think this leads us to exploring the definition and discussing the properties of this state of matter.
According to dictionary.com and the American Hertiage Dictonary, a liquid is the state of matter in which a substance exhibits a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility. Therefore, in order to qualify as a liquid for this project, the substance must flow, not evaporate into vapor readily and be incompressible. (this means you can’t smoosh it into a smaller space)
Some have asked, “Can I use water with things mixed in to change the density?” You can try this yourself, but think this out. If you mix salt with water and if you mix sugar with water, when you pour this into the same bottle, since they are both water, won’ they mix? Think about substances that don’t mix with water. Maybe you want to try these. Maybe you want to check out some properties of water according to the US Geological Survey’s site on water. This might help you decide whether or not to even use water.
I know you all are adjusting to being back at school, but so are the teachers. We have many new things to work toward this year, and I am very excited to get started. Hopefully your time in my class will be a rewarding and educational experience, and we will try to have a little fun while we’re at it.
Here is a list of all seniors exempt from my finals. If your name appears, congratulations, you do not have to take finals. If your name does not appear, your current grades or absences have removed you from the list and you are required to be at the review session on Monday and be here to take my finals Tuesday and Wednesday. If you have any questions about this, please see me. A few people are very close to being exempt, so these people may have their names added to this list, but if your name is already here, you are locked in as safe, as far as I am concerned.
