i should not go to my one hour thirty minutes apchem class but just watch this instead im serious thank you!!!

is the online tutoring expensive?

[bannanaiscool]

@pigsbum53 10 bucks for 25 hours of video!

your a freaking life saver ... my teacher doesn't do any example problems she just talks n has her powerpoint ... im sad that you didnt explain half lifes because i dont understand those either but hopefully i can find a video on it as good as yours

[bannanaiscool]

Half life formulae are over-rated. Just use the first order integrated rate law expression any nuclear decay questions. If the equation has percentages, treat those as concentrations where [A]o is the 100% and [A] is the percent left at the particular time.

Honest, it works.

I'm sure that your students are the best in chemistry. you are a truly model for all the teachers in the world and you should know that. thank you again. by the way I study medicine 1st year in Budapest.

[bannanaiscool]

And you are also very kind. Thank you for the encouragement.

this guy is unbelievable. He explains it great. start at the beginning and go through it all and it is so much clearer than in class!

[venisuasia]

wooow this is sooo much better than class :oo

[Hiitsme1994]

@david2131 I was born in Budapest :) But my AP chem class isn't very informative either.

[marcthepolo123]

@bannanaiscool wow your vids are amazing, wayyyy better than my teachers lectures!! i do have a question though, is there any tell tale signs that indicate a second/zero order like the (s-1) for first order, and if the graph representing concentration vs time or the natural log vs time is exponential or curved instead of linear what does that represent? thanks again for the vids btw!

[redsoxman4life]

the ending to this video sounded like a threat... haha. But really, I can tell your are a great teacher. Thanks for the help! I'm sure I'll be referring to your vids in the future.

[dimseeeen]

wat makes them fast/slow and how can u tell???

[lKoRuPT]

To get the activation energy you need to plot the natural log of k, the rate constant (y-axis) against one over the temperature in Kelvin (x-axis). Then get the slope of the line and multiply it b the constant, -R, where R is 8.3145 J.

[TeamoXixi]

Here, I have a question....

For the activation energy, I dont get how to get the slope.

do i just use the equation u wrote on board?

[TeamoXixi]

Thank You So..o Much.

I'm trying to take the ap chem test, but I missed the chance to take the class.

our school's ap chem teacher has been discouraged me to take the test all the time.

And ur videos help me so...o much!!!!!!!!!!!!

Seriously, u are such a good teacher+life saver!

You should make some vids to teach my teacher how to teach, sometimes i can't even comprehend what my teacher is trying to get at during her 1.5 hour lectures, it's very comforting to know that when i get home, i can watch a couple of your vids and ace the test because in usually about 15 minutes to half an hour i will have a much better and more full understanding thanks to you. If i get an A on my next test you're totally gonna get a generous donation. My teacher is nothing compared to you!=]
