I hope your break has been relaxing.  Below is a list of tutorials and practice problems to help with the long time off.  I hope it is helpful.

TUTORIALS:

Factor Label Method (Dimensional Analysis) Tutorial 1

Factor Label Method Tutorial 2

Ionic Compounds Tutorial 1

Ionic Compounds Tutorial 2

Predicting Products Tutorial

Balancing Chemical Equations Tutorial1

Balancing Chemical Equation Tutorial 2

Writing Ionic Chemical Equations Tutorial

Moles, Molecules and Masses Tutorial

Stoichiometry Tutorial 1

Stoichiometry Tutorial 2 LIMITING REACTANTS - This is new and will be covered soon after our return to school


PRACTICE (all contain answers keys):

Predicting Products/Identifying Reaction Types

Balancing Chemical Equations

Combination of Predicting, Identifying and Balancing

Stoichiometry Practice (mole and grams)

Mole to molecule conversions and more Stoichiometry
pages W3 - W4, # 12-22
pages W10 - W13 (W13 includes limiting reactant problems if you want to try).

New Simulations Added

Check out the right side of the blog for 2 new simulations.  One is on Balancing Equaions and the other is Simple Stoichiometry.

Here are some practice problems associated with Stoichiometry

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
