Final Thoughts

So guys, we have had our ups and downs. I have enjoyed having you in class (besides the paper balls and laser pointers). For your final post, due today, I would like to know what part of this class you liked best or learned the most about chemistry.

I have counted up blogs and will post it today so you know where you stand.

Good luck and I hope to see you next year or the year after in AP Chemistry.

Hey guys I though I would just remind everyone that it is seriously important to do well on your exams this semester as well as the chemistry exam. The second semester of sophomore year and the first semester of junior year are what most colleges tend to look at the most. If you don't have very challenging exams one day (like religion or ethics) it is proabably a good idea to start studying for harder exams like math and chemistry on that night. Good luck to all.

I am guessing that I still need to get some more blog points so I am putting one up.

We have a test over chapters 14 and 15 on Monday.

That plus the exam is all the chemistry we have left.

Hello fellow students. We had quite a fiasco yesterday with paper balls and laser pointers. Let's try to do better today.

Ok, so blog-wise, we have a test on Monday over chapter 14 and chapter 15. And our exam is on thursday. So it looks like we are going to have to hit it hard this weekend, like Ben and those balls.

good luck, we REALLY need it.

Okay guys, we had a quiz today over acids and bases. Is it just me or did Dr. B say yesterday that it was going to be on stoichiometry? But anyways we have a test on Monday that is going to be over both chapters 14 and 15. She wants us to have both calculations and conceptual questions. I suggest that you start studying now for the test because it's an exam day and we have shorter class periods.

5/11/10: Exam Review

Hey guys! Guess how smart Jim is! I'll give you a hint: he forgot to bring home his Chemistry notebook two days in a row. But fear not! I've recreated an outline of the stuff we need to know for the exam with my book. This probably covers more than we talked about in class, so feel free to correct me in the comments.
  • The exam will go from chapter 7 to chapter 15. Here are most of the important terms and concepts from each chapter, as found in the end of chapter summaries.
  • Ch. 7: Formula mass, percentage composition, empirical formula
  • Ch. 8: Chemical equations, precipitate, types of reactions, electrolysis, activity series
  • Ch. 9: Stoichiometry, limiting reactant, excess reactant, theoretical yield, actual yield, percentage yield
  • Ch. 10: Kinetic-molecular theory, ideal gas, real gas, fluid, surface tension, capillary action, crystalline solids, amorphous solids, phase, equilibrium, molar enthalpy of vaporization/fusion, triple point, critical point, critical temperature, critical pressure
  • Ch. 11: Pressure, mm Hg, pascal, atm, Dalton's Law of Partial Pressure, Boyle's law, Charles' law, Gay-Lussac's law, combined gas law, Gay-Lussac's law of combining volumes of gases, Avogadro's law, ideal gas law, ideal gas constant, Graham's law of effusion
  • Ch. 12: Solubility rules, solvent, solute, solition, suspension, colloid, electrolytes, saturation, miscible/immiscible, Henry's law, effervescence, enthalpy of solution, concentration, molarity, molality
  • Ch. 13: Net ionic equation, spectator ions, ionization, strong/weak electrolytes, colligative properties, molal freezing-point constant, freezing-point depression, molal boiling-point constant, boiling-point elevation, osmosis, osmotic pressure
  • Ch. 14: Binary acid, oxyacid, Arrhenius acid/base, Bronsted-Lowry acid/base, monoprotic acid, polyprotic acid, Lewis acid/base, conjugate acid/base, neutralization
  • Ch. 15: pH, pOH, titration, equivalence point, end point, standard solution, primary standard
Also, I would like to remind everybody that you should eat chocolate before all of your exams.

Hey Guys, there was no blog last night so I decided to make one. The notebooks are due tomorrow and she is counting up our blogs. I hope everyone has enough!

Once again guys, I need blogs so I guess I will keep on posting until we have an assigned blogger. On Friday we retook the quiz and I think most people did much better. Thank you Dr. B. We took about 15 min. before the quiz to review the material on it and it really helped me. After the quiz we just chilled out for the rest of class. Our test should be coming up fairly soon so start studying.

Ok I don't know if there was a scheduled blogger for tonight but I need posts so I am going to go ahead and give one.

I (and many others) failed the quiz today so Dr. B. is letting us retake it tomorrow. You need to know how to calculate molarity and how to use acids (H3O) and bases (OH) in calculations. You also need to know how to apply pH and pOH in calculations. In addition, you need to be able to tell weak acids apart from strong acids and weak bases apart from strong bases. Good Luck!

5.5.10.

Hey guys, just thought I'd go ahead and get a blog up here.

Well, today in class Dr. B showed us how to do all of the needed calculations.

In conclusion, lab is due tomorrow as is the homework from the text book; remember to get it all done.

*NOTE* - on your lab, be sure to show calculations, sig figs, and label your work for clearer understanding; you can never use too much partial credit. Put the pre-lab and post-lab questions INTO your Lab Notebook as well.

Well, have a good night guys.

Wasn't there supposed to be a blog last night? Well, yesterday was the last day for lab. Everyone remember to do your post lab questions!

Tomorrow is LAST DAY for lab. Remember you are supposed to have 3 titrations with KHP and 3 titrations with Vinegar.

On Friday, we continued our lab. Our goal was to complete 3 titrations. Did everyone meet the goal?
