Polyatomic Ions and Introduction to Chemical Reactions

Here is the list of polyatomic ions that you need to know how to draw Lewis Structures for:

Carbonate
Nitrate
Nitrite
Hydroxide
Ammonium
Hydronium


Here is a synopsis on chemical reactions

Here is a video/animation on chemical reactions

Here are practice problems for identifying reaction types and balancing equations.

Biochemistry Quiz - Caffeine

For the atoms labeled I - III

label the molecular geometry (shape) and the bond angles.


Choose any other carbon that is NOT like Carbon labeled I and make that atom IV.  Label its molecular shape and bond angles.

Molecular Geometry / Polarity Practice

Tutorial on polar vs. nonpolar

Polar vs. Nonpolar Practice Problems  (with Ionic!)

As for practice problems thinking about molecules in 3D - go to the applet to the right and look at the "real" molecules.  Try to build them using only the formula and then click on them to see if you were correct
