Dear Dr. Lavelle Thank you for your dedication and enthusiasm that came along from you teaching this class. Coming into 14A last quarter I had no chemistry knowledge what so ever, but now finishing 14B I can say that I have truly learned more than I can imagine. I am going to miss this class as well...

I also agree that Kahn Academy is very helpful. I also made flashcards on quizlet to help me memorize the different names.

They are the most common because they are highly stable and show up in DNA, RNA, and Sugars!

BF3 is an electrophile because B only has 6e- but it can have can have 8e- since it is an octet.

I think we still have to know them because they were part of our homework problems.

I was going to make a joke about sodium and hydrogen but NaH

The 10 comes from the specific half reaction of BR2 + 2e ----> 2Br-

Do you know what time we can pick up our final exams for Chem 14A Fall 2016?

Yesenia Munoz 1G

Do we need to have table 8.7 of the mean bond enthapy memorized for the quiz?

Yesenia Munoz 1G

On the midterm and the final there is always one problem taken directly for the homework problems. However, doing the homwork problems will preprare you for the quizzes as well, because the quiz problems are similar to the homework problems.

Yes. It willl count as long as it is before Sunday at midnight. For example, For week 1, you must post before Sunday January 15th at 11:59 p.m.

Will we have to memorize each Ka for common Acids and Kb value for common Bases, or will they be given to us for the final?

Yesenia Munoz 1G

The equilibrium constant for any reaction, is called the water dissociation constant which is Kw. Because every H+ (H3O+) ion that forms is accompanied by the formation of an OH- ion, the concentrations of these ions in pure water are the same and can be calculated from Kw. Therefore, Kw = [H3O+][OH...

Does Bruin cast work on an Ipad or Iphone?

If we have a Thursday discussion will we have to wait to get our quizzes back until week 10?

The Chloride is placed after the amine, because the amine in this case always come before the element that is listed after the ion in parenthesis.

Yesenia Munoz 1G

The Central Atom can only have an expanded octet after the 14 element. However, it is a case by case basis, meaning that if it says to follow the octet rule, then depending on the elment, it can or can't have an expanded octet.

Are we allowed to use fractions when balancing chemical equations as long as we put the coefficient at the front of the equation?

Yesenia Munoz 1G

I believe we are supposed to write it in increasing numberical order.

Why do chemists like nitrates so much?
They're cheaper than day rates. (:

Yesenia Munoz 1G

I believe that the extent of the change in the electoral field at any given point decreases. The amplitude of the wave is not the one decreasing.

Making flash cards on index notes or quizlet really helped me memorize prefixes, suffixes, and abbreviations for the elements, when you are given a problem in word form.
