klmama Posted November 12, 2014 Share Posted November 12, 2014 We've hit it - the dreaded stoichimetry. What is the best online help you've found? Quote Link to comment Share on other sites More sharing options...
Jen in NY Posted November 12, 2014 Share Posted November 12, 2014 There are some videos here - maybe #s 801 and following? http://www.gpb.org/chemistry-physics/students/all Quote Link to comment Share on other sites More sharing options...
wendyroo Posted November 12, 2014 Share Posted November 12, 2014 Khan Academy has a series of stoichiometry videos. Wendy Quote Link to comment Share on other sites More sharing options...

Dicentra Posted November 13, 2014 Share Posted November 13, 2014 If your student has questions, I'd be happy to answer them. I like to use cookies as examples when teaching stoich. :) Quote Link to comment Share on other sites More sharing options...

I like to use cookies as examples when teaching stoich. :) I like to use cookies as examples when teaching just about anything. Preferably actual cookies to enhance the verisimilitude.

How do you use the cookies? Do you use the recipe to show how limiting reactants work, or do you use the actual cookies in some way? (Please say actual cookies so I have an excuse to bake tomorrow!)

(Please say actual cookies so I have an excuse to bake tomorrow!) :D I suppose you could use the recipe but I mostly tend to use the idea of Oreo cookies to teach stoich, limiting reagents, and the idea that stoich ratios only work when you use moles (i.e. counted numbers) and not masses. I think I once explained it briefly in another thread... Here it is: http://forums.welltrainedmind.com/topic/527522-long-term-prep-and-plan-for-physical-chemistry/?p=5925708 I like cookies. :) Quote Link to comment Share on other sites More sharing options...
