@micn6ll6 omg -__- i know how you feel! i'm sitting on my ass all day in class, trying to figure out what the hell my professor is telling me for 4 hours straight and now i know...youtube is a better tutor XD
please could some one explain why the molar (moles per litre) is not split into its atomic/molecular ratios in these vids? ie HF (aq) ->H+(aq) F-(aq) = 1M H+ and 1M F- , as a mole of HF has a different number of atoms of H and F?
my chemistry teacher named mrs. fosse doesnt teach shit, so i have to go online and look for chemistry tutorials... smh but this is so helpful.. so sad that an online podcast is more helpful than an actual teacher... smfh
Equilibrium reactions and how they are affected doesn't only depend on temperature, as you describe at around 00:37, but on concentration of reactants and products as well, including the pressure of any gas present in the reaction.
If someone says that they have something with a pH of 0 that they would like to maybe throw at you.. you should, you should, you should decline. It will probably hurt your chances of.. anways. LOL
I sat here for an hour and tried to put your incoherent ramblings into some kind of formula i could take to a worksheet and couldnt. then moved on to your next video, and the same thing. For someone coming with a complete blank slate to this its ridiculous to try and follow you man, try to get it into terms that people can use practically. i mean your talking AT me. im fucking pissed enough to write a comment, wasted a couple hours, its getting late, and gotta learn this for a quiz tomorow.
@Peace722 i know dog but you know what its like sitting and reading from a book. Im trying to get everything easily fed to me. some of these other videos on here, (i was gonna delete my angry comment and post a link but thought fuck it. are easy for learning shit, like better than a book. gottta 86 on the quiz sonnnn
@noreggi@noreggi All these videos don't cover everything you need to know for an exam. You CAN'T rely on them. I have a book that cut's all the crap and gives you exactly what you need to know for an exam. You just need a good book and once you know the underlying details you can use these videos to re-call info.
You have to read your book before you come to these videos. This guy is giving you a summary for revision, not what you need to know A to Z or how to do every calculations.
Some people can't just "read the book" and get an intuitive grasp of what it is saying. They NEED a video like this to put the subject matter into understandable terms.
"If you have someone saying they have something with a pH of 0 that they would like to, maybe, throw at you, you should decline...b/c it would probably..."
All your videos has been a GREAT help for me in Chemistry A. Thanks a lot man! =) Keep up the good work, it´s awesome! A funny thing is that you explain everything much better then my chemisty teacher, haha! / Student on Mittuniversitetet, Östersund, Sweden
You should decline from offers of strong PH getting thrown at you,because it will hurt your chances of having children :).

In all these videos, he keeps saying 'disassociation', while the ionization in chemistry is simply 'dissociation'.
