  • You should decline from offers of strong PH getting thrown at you,because it will hurt your chances of having children :).

  • Knew it. Fuck classes - hail Youtube ^.^. Worked in Highschool , still works in College :-)

  • I'm glad I've learned more in your 15 min video then i have in the past 6 lectures with my chem. professor. thank you!

  • @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

  • I'm gonna go with the average of "fourteen" and 17.

  • i dont understand anything, (cuz i'm still learning about moles)

  • 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?

  • @dasraiser i meant molarity..

  • With your videos, I could skip lectures and homeschool myself. 

  • 3 people didnt get it

  • penis at 3:56

  • @AnotherBrownKid What grade are you In??

  • @diceman424 11 now 12 after summer.

  • @AnotherBrownKid Oh just wondering. The penis comment automatically made me assume that you are in the 6th grade. Sorry

  • 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

  • good video

  • why should you decline?

  • I hope i'll pass chemistry 1 examn tomorrow with this! wish me luck..

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

    Just thought I'd point this out.

  • HAHAHA! epic moment when he said "YOU SHOULD DECLINE".

  • @dyepribudoy

    well, it'll probably ruin your chances of, well, never mind <3

  • hahah, you should probably decline from getting strong base thrown at you. Love it.

  • good vidreo I would like see more videos likje this it was so helpful! for me have you got a video of Ka Kb / Kc/p Kps... thankss!

  • What a beautiful mind............

  • 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.

  • Our chemistry teacher sucks big time! Your videos help me :)

  • Hello, I learn more from your videos then in the classroom. Thank you fro doing this.

    Greatings from Norway

  • @xsroo ikke sant! LOL

  • 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 love your videos if you didn't have these i would have failed chemistry.... but instead i'm going to AP chemistry!

  • it is nice you always start with.......with know that!!!!!!

  • I'm an italian student and I've found your videos way more useful than my teacher's lectures....so thank you!

  • "You should decline because it will probably hurt your chances of...well, anyway..." haha awesome!

  • Change 17 to 14 @ 12:48.. Thanks for the video!!

  • 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.

  • @noreggi maybe don't leave revising to the last minute...

  • @noreggi

    use your book, dumass.

  • @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

  • Comment removed

  • @noreggi 

  • @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.

  • @Peace722

    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.

  • LOL if someone wants to throw a solution with a pH of 0, you should decline, lol

  • Excellent lecture much more clear then my normal ones.

    O and it's 14 at 13:00 not 17

  • I rather stay at home watching and listening your videos than going to school listening to my boring lecturer's crap. YOU ARE AWESOME!

  • "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..."

    That Sal made my day.

  • Ph means water?

  • "so your pH is...14!" *writes 17*

    LMFAO I love you Sal!!!

  • Thanks for this!!

  • Genius

  • Good stuff, Helping alolot studying for the MCAT

    Keep it up!

  • great lecture .

  • 13:22

    LOL

  • hahaha !!! lool

  • tanx man

    it is great!

  • 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

  • sickkkk

  • 12:48

    pH = 14 , you wrote 17 lol, its alright though. You said what you meant. :)

    Btw, these videos have been a great help to me in my Chemistry class!

  • @Slicksz Well, but please correct it. It's so confusing.

  • Great Video Sal ! Keep up the good work.

    ps: Am I sweet or acid today ? :-)
