  • i hate my chem teacher

  • THANK YOU!!!

  • hey what about the coefficients? you did not use them.

  • Dude try for NextUp, I'd vote for you :)

  • Great video! I feel like you always use the word "weight" I always understood the periodic table elements "masses" being measured. I feel like this simple substitution of this word could confuse people when they have to differentiate between the two.

  • replace my chem teacher please

  • YOUR THE BEST!! I finnally friggin understand how to find the limiting and excess. But I am still pretty lost on what to do when you are given the moles instead of grams and when your are given 1 mole and 1 gram. Do you have any videos on that? or willing to do them? I can follow along with grams given and get to the moles, figure ratio, limiting, excessive. But when given moles or a mix I end up drifting off.

  • HELP! I realized that rounding of the numbers makes a big difference in answers. How many significant numbers should I round the numbers to?!

  • You are a wonderful human being!

  • quick question: why do you use the ratio as H2 / CO and not the other way around? just a bit confused how you chose it that way instead of the other way around

  • I found this somewhat helpful, but man you totally over complicated things. There should only be three main equations and then one little subtraction equation. Thank you anyway though! Still helped :)

  • Use CHO

  • I wish u can replace my Chem teacher....she makes things so complicated...this was soo much easier to understand

  • I LOVE YOU. Thanks for the effort you put in to each us stupid kids. :)

  • zzzzzzzzzZZZZZZZZZZZZZZZzzzzzz­zzzzzzz

  • life saver man.

  • this is a awesome video but i got one question, if u were asked a question like part b, which method should u use in an exam, and would both ways be correct?

  • moles. mole-lecular weight.

  • I found that useful.

  • Thank you, that was quite refreshing! I owe myself to watch every single video, this summer. Kind of like a marathon.
