Exam Prep

Here are some new practice problems to aid in your exam prep (NOTE:  Not every question relates to what we have covered.  We are at a different point in the material compared to last year, so there are some questions that reference material we have yet to cover.  Ignore them please.

Practice 1 (old quiz)

Practice 2 (old quiz) - this reference using the "back of the sheet" - there was a periodic table copied with it.  Use your own periodic table when needed.

Practice 3 (last year's exam)

Practice 4 (EM Radiation)

Practice 5 (Exam from 2010)

Naming Ionic Compounds and Covalent Molecules

Here is an online quiz generator for naming.  You may not be REQUIRED to know the same ions quizzed here, but most should be familiar.  If need be, look up what you are not supposed to know and use it properly.  You can continue to click TRY AGAIN to get new questions.

Also,  I have posted two Naming Tutorials under class resources.  They walk you through the steps taken to correctly name chemicals.

Update to Class Resources Page

The Class Resources page has been updated to include presentations for Unit 2.  Please add them to your studying before/after class, in addition to the suggested readings.
