Document Summary

Last time we used a color wheel . Monday, march 9, 11:00 monday, march 16, 11:00. 30 40 minutes (yet to be determined) Only weak field (high spin) ( tetrahedral < octahedral) Don"t forget to spring time forward this weekend, meaning your final exams are sooner than you think . Overall for square planar complexes (coord. number 4) Strong field (low spin) ( square planar > octahedral) Always the observed (experimental) results are preferred to the theoretical predictions. Energy is the capacity to do work or to produce heat. One can"t measure the absolute energy of anything. We can only measure energy transferred in and out of something. Even that is done indirectly by measuring heat or work. (joule) E = heat + work = q + w. Work energy transfer due to an applied force . Heat energy transfer due to a difference in also used kj, calorie, kcal temperature (textbook simplified definition)
