AP Worksheets (and Answers) 12a, 12b and 12c have been re-written and placed in the subscriber areas. These worksheets reflect the change in the Net Ionic Equation writing section of the exam for 2007. Since we still have very little to base our thoughts upon, the questions associated with each reaction are currently what I would call a “best guess” as to what may be asked. Since the College Board remains reluctant to release more specimen material (for whatever reason) until we get several years worth of material these guesses will have to do.  From conversations with a number of my colleagues, there seems to be a consensus that what I have put in these worksheets represents a pretty good set of guesses – we’ll see!
