Chem II AP


March 19, 2018

This week we continue Chapter 18, Spontaneity and Free Energy. There is no lab for this short unit, and the test is scheduled for Friday.


Update 3/21: As mentioned in class on Tuesday, as a result of today’s snow day, all of the Chapter 18 review material will be due and checked on Thursday. See calendar below and updated Syllabus for details.


Here is an online Mahjong game (needs Flash) in which you can practice concepts such as oxidation number, names & formulas of polyatomic ions, solubility (precipitation reactions), isoelectronic species, and names & symbols of the elements.


The calendars from September through February have been moved to the Old Calendars page, where all of the links will remain active for the remainder of the year.
