Where to find study sheets
Email me your study sheets using anniemarostica@hotmail.com This will allow larger files than my school email. I will then post all study sheets under projects. SL will have separate projects for each period: Study Sheets P.1 and Study Sheets P.2. Make sure you click on the correct project! Remember, the projects must be emailed by 6:30pm MONDAY night.

IB Jigsaw Project
Schedule:
Friday
"Expert" groups were arranged and assigned one of the following topics:
1-Naming
2-Empirical/molecular formula and limiting reagents
3-Bohr's Model and equations with frequency, energy, wavelength, speed, and Planck's constant (h)
4-electron configuration, isoelectronic ions/atoms, periodic trends (size, electronegativity, ionization energy, SHIELDING)
5-Lewis Dot Structures (ionic, covalent, resonance)
6-Valence Shell Electron Pair Repulsion Model (VSEPR)
7-Polarity
Groups got together and brainstormed about how to organize their study sheet. *Remember* The best study sheets are concise and well organized. The use of graphic organizers is highly encouraged. This should be a resource for all students to use at a glance. The front of one page is ideal and it should NOT EXCEED one page front and back.
The guide MUST CONTAIN 3 examples and 3 problems for the other students to practice.
Monday
Create your study guide in class. Type up the guide and submit over email to Ms. Marostica (can't post documents on blog :( ). This is due NO LATER THAN 6:30 Monday night. Ms. Marostica will try to post these sheets on the website monday night but may not be able to as she will be out of the state. SO, it will be required that every expert group member have a copy of his/her own groups study sheet. For example, on Tuesday, every member of group 1 should come to school with a printed version of the study sheet. Make sure you exchange emails so you can send everyone a copy.
Tuesday
One member of each group will get together with each other. This means we will have several groups of 7 people. Each person will get 7 minutes to explain his/her topic. During this time, at least one problem should be attempted by the group with the help of the expert to guide them through the process of solving the problem. Ms. Marostica will post all study guides Tuesday night so you can review them for the quiz. The quiz will directly focus on topics 5-7 but you will need information from all topics to be successful as the material builds on eachother.

Magnesium oxide lab
Hi chemistry studs!
Per. 1, we will be re-doing the lab on monday, instructions to follow in class on monday. For now, you should be reviewing and working limiting reagent problems. Please be ready to begin lab ASAP because I am going to try to do something else that day as well.
Per. 2 and 5, if you did not get a positive mass for grams of oxygen, please use the following data to calculate the mole ratio of Mg:O.
Mass of equipment (no Mg) = 29.809
Mass of equipment + Mg = 29.935
Mass of equipment + magnesium oxide = 29.990
These are not necessary correct results, they are simply sample data from another student's lab. The correct empirical formula is MgO (ionic bonding rules: O is -2 and Mg is +2 so they go together in a 1:1 ratio).
Use this data if you didn't get data that makes sense i.e. the magnesium oxide weighed less than the magnesium.
We will have a post lab on monday and start on chapter 7.
Hope your weekend is going well,
Ms. Marostica

lab info
The error bars should be set at 1, not .5. This is because you have to account for the .5 error twice when you subtract the two temps.
The actual ratios are as follows:
Bleach:Na2S2O3. 4:1
Bleach:KI. 3:1
Bleach:Na2SO3. 1:1
Also, checked on IB policy and you don't have to write the procedures in past tense...yea!

Graphing in Excel
Hey guys,
I posted directions for graphing in excel on the website under files to download. If you have any questions, shoot me an email or better yet, add it to this blog so you guys can help eachother. I'll of course chime in. Also, don't worry if you don't understand the directions or get confused. Just do the best you can because tomorrow we will hopefully work out the confusion.
