CHEM 1311

 

Alrighty…  Time to dive right in with some awesome websites that will help with information on the first two chapters we will be tested on…

First, a few really great online calculators to help check your homework when converting back and forth between different units of measure in the decimal system.  I recommend just using these to check your answers so that you are working the problems the correct way…after all, we won’t have these for help on the exams…  :(

Next, I’ve got an EXCELLENT site on converting to numbers to Scientific Notation.  This site explains the rules for addition/subtraction and multiplication and division, AND (this is the best part!) offers an interactive quiz for you to practice.  30 minutes with this site, and you’re golden.

And…the moment you’ve all been waiting for…a calculator to check your answers for Polyatomic Nomenclature conversions!!!  YES!!  Courtesy of UNC – Chapel Hill, you can put together all kinds of combinations.  Plus, there’s a plethora of other great chemistry information and tutorials here.  Basically a JACKPOT!!  :)

Between these 4 sites, I think just about everything we could possibly be asked on the exam is covered in some form or another.  But, later this week, I’ll post all my notes that I’ve taken from the book on Chapters 1 and 2.  Look for those probably sometime on Saturday.

 

Happy Studying!
