I may be wrong, but is not -232kj MINUS 37.7kj = -269.7? if you subtract from a negative, shouldnt the answer be more negative?

Could you check the entropy value -118.0 j/mol, in the sample you used 118 kJ instead of J/K.
Good job though, I really enjoy your videos.

defining entropy as disorder is actually misleading. Entropy isn't really about disorder or chaos, but rather becoming equilibrium with the environment. A great example is a drop of ink into a clear glass of water. The ink drop can be best described as trying to become equilibrium in concentration with the glass of water instead of becoming more chaotic. Because after the equilibrium has been reached, "chaotic" process sort of dies out.

@1006Will Good thing she's super articulate :)
-
she didnt convert J of Delta S to KJ.
-
she talks wayyyy too fast.
-
how come your entropy is in the form of kJ? shouldn't it be in J/mol.K?

@brightstorm2 at 3:20 did you do that math in your head if so where did you learn to day math like that in your head I am a fairly intelligent person and it took me about 3x as long to do that.

Thanks for making this video

I think in the example problem the unit for dellta S was NOT converted to KJ in order to apply like terms with delta H.

Is there any button more than 5 stars :)
************* ive made it though :D i agree with someone above that u gotta slow down a bit . Cuz this is one of the most difficult part in chem 2 i guess. I have my own favourite channels that help me with chem but for this problem...i never find those useful except this one. Thanks a lot for uploading this. And if u have time plz label ur vids with more specified details so we dont get messed trying to search ur vids...cuz before i came up with this...
