Question
One of these rules states that oxygen polyhedra may share corners but not edges or faces. For 10 points each:
[10h] Name this series of four rules, named for a University of Chicago professor, used to empirically predict an oxide’s ability to undergo glass formation.
ANSWER: Zachariasen’s (“zah-kah-RAI-ah-senz”) rules
[10e] The first of Zachariasen’s rules states that for a glass to be formed, no oxygen atom may be linked to more than two of these ions possessing a positive charge.
ANSWER: cations (“KAT-eye-onz”)
[10m] This oxide has been shown to violate Zachariasen’s rule and can form into glass despite having its oxygen be linked to three cations. This oxide and iron comprise the most prototypic products formed during a thermite reaction.
ANSWER: aluminum oxide [or alumina or Al2O3; reject “aluminum”]
