Document Summary

Final lab exams start next week for some students. Stronger ra + stronger oa react spontaneously to form weaker ra and weaker oa. The more +ve e is, the stronger oa (e. g. f2). The more ve e is, the stronger ra (e. g. alkali metals) Look at table 8 on my cds (arranged differently than in the textbook) I recommend that you summarize each experiment (concepts, pre and post lab calculations) on one page and then study from those pages. I have uploaded the lab sample exam onto eclass so that you can practice under exam simulated conditions. Last time we looked at a cell of cu and zn solutions. E = 0. 342 ( 0. 762) = 1. 104 v. So the net spontaneous reaction using the diagonals for reactants (blue) and products (red) In a net reaction there wouldn"t be any electrons. Electrons do not float around in a solution! E and g are both measures of spontaneity.
