Pariah Posted July 29, 2018 Author Report Share Posted July 29, 2018 I'm posing a question to my Honors Chemistry class the first week of school this year: What mass of dry ice is necessary to displace the atmosphere from this room and fill it completely with carbon dioxide? To answer this question, they'll need to do a lot of measurements and calculations (especially conversions!). And I may have them determine experimentally how much CO2 5 g of dry ice will produce when it sublimates. Old Man and Cancer 2 Quote Link to comment Share on other sites More sharing options...

And I may have them determine experimentally how much CO2 5 g of dry ice will produce when it sublimates. Next time I teach that class, I'll do another version of that, involving liquid nitrogen istead of dry ice, since a good-size spill of LN2 is easy to imagine in a lot of labs.

Pariah Posted July 29, 2018 Author Report Share Posted July 29, 2018 That'd work, too. The University of Utah's Chemistry department will sell me LN2 for something like 25 cents/liter...or would, if I had the Dewar to put it in. Quote Link to comment Share on other sites More sharing options...
Cancer Posted July 29, 2018 Report Share Posted July 29, 2018 At the university, of course, there's LN2 in ... well, perhaps most labs, so doing that calculation would be directly applicable to lab safety. Nothing wrong with assignments that address two important topics simultaneously. Quote Link to comment Share on other sites More sharing options...

No, you need to go full Bond villain: "There is a mass of solid CO2 by the whiteboard that is 1/600 the volume of this room. It began sublimating at the beginning of this exam. Do I expect you to talk, or do I expect you to die?" Also, to answer your second question, 5g of dry ice will produce 5g of CO2 when sublimated.
