hey man u are amazing..

if i would buy you a house and pay for your visa and flight to get here in england

would you be my private chemistry teacher ???

lol :P

[MarkRosengarten]

@Momentum7Edits Gotten a lot of offers over the last few years...but what would my own students think if I abandoned them? :)

[biancutie]

our teacher makes us report on these things which is why we can't understand anything because no one is explaining it properly to us. It's a good thing you post these things on youtube or else i would not have understood anything in our chemistry class :)

[MarkRosengarten]

@biancutie What's even better is that the new Race to the Top standards are going to mean that more and more of your teachers are going to be doing things that way...myself included. I'm glad I have these videos, too. Businessmen are telling us how to teach, people who have never stepped foot in a classroom themselves. We have to do what we can to survive this insanity.

can u tell me why CH2Cl2 is a polar bond? isnt the EN difference 0.3 meaning non polar bond?

[MarkRosengarten]

@cobalt2black You can evaluate the polarity of any single BOND, but when you are dealing with the polarity of an entire molecule, it's a different matter. The bonds between C and H are weakly polar, but the bonds between C and Cl are strongly polar.

[MarkRosengarten]

@tansrn1 1) The polarity of the bond and the polarity of the molecule are different things, 2) I teach in New York State and I am using the New York State Chemistry Reference Tables, which give 2.1 for H. I know it's 2.2, it used to be listed at 2.2, but it's a state mandate so I have to teach it as 2.1

So helpful he does a good job of cutoff your attention

I love your videos they are easy to understand and funny:)

Haha! That's the way Chemistry should be taught!!
