For the test on Wednesday you will be able to use the IB data booklet. This is the booklet the IB Organization allows you to use on the test. You will be able to use this booklet on every test in my class. This booklet is 38 pages long and is mostly filled with information you do not need at this point. The info that will be useful to you for the summer packet test includes:
Avogadro's constant
Periodic table
Unfortunately, you are not given a chart of common polyatomic ions so you will need to be familiar with these coming into the test. I would suggest making flashcards. Your test will include naming chemicals from formulas and stating formulas from names, writing and balancing equations, and simple stoichiometry with accurate significant figures. Again, let me know if you have any questions.

I til don't really understand what I'm doing on the stoichiometry! I get the part of limiting reagents. Not the grams-grams problems the first ws on stoichiometry. I'm more of a visual learner.
What if we don't finish the things that we don't understand?
Like the reaction Worksheets. I got the stoichiometry off the online tutorial but the Reactions on does not really help you.
Every problem needs to be attempted and not left blank. It is okay if it is not completely finished or accurate but there must be evidence that you attempted the problem. You may want to write down a specific question that gives me SPECIFIC information on what you don't understand.
The stoichiometry worksheet goes right along with the stoich tutorial. Choose the 5th one on the list and follow the steps as best you can. If you only get half way it's okay but I need to see evidence that you've attempted the problems. Hope that helps.
I have posted a list of the polyatomic ions, a helpful ppt that you can use to test yourself, and a ppt on significant figures. Feel free to post questions on the blog. Good luck.
where is the polyatomic chart thing? I cant find it.
Yea neither can I...

Go to projects in the month of august and click on summer packet review. It is the word doc.
so we need to know all those? ( in the link posted here, because I still can't find 'projects' or anything) Because that's more than 15, it's 42 And they have names like tartrate and hexafluorosilicate. A little stressed, and I dont know if I'm looking at the right thing. Ms Marostica, if you have a link right to your post, it would really help, because then maybe I can work my way back and see what projects you're talking about and all, I see only 3 posts for august, and none of them contain the polyatomics. Thanks.
Oh! I found it, on your teacher website. Ok. Cool. So we need to know all from categories 1-5 in the word document? Nothing else? Less?
What do the * next to the ions mean?
The ions with the * are more commonly seen.
Yes, any ions on the chart are fair game but you are most likely to see the ones with * on tomorrow's test and in the future.
SiO4 4- and SiO3 2- are both called silicate?
HSO 3- HSO 4- are both called bisulfate?
Ok, so only the word doc then. At least, thats what I assume. Because the other nomenclature thing that got posted was scary.
The powerpoint has some ions not on the word doc
Just worry about the ions in the word doc. The ppt is just a tool to help you memorize and I did not post that other nomenclature list but it does have some helpful stuff. It's good for you guys to post things for eachother! That's the point of the blog.
