FINAL 2012

So, the final exam is cumulative and definately NOT curved.  Here is the material that is on it.  You can check out everybody's typed final homework in the CHEM drive for possible questions.  We will review a little this week.     Here is a link to a review final exam.  https://docs.google.com/document/pub?id=1jlKSXabJO0rhc1vrAg54UXKYmG6NXUHu5kV_Rv8UmiY

SEE NOTES FROM ALL OF APRIL and MAY's CHEMISTRY BLOGS (including this one) for review of material!

Stoichiometry Experiment

We are currently working on a Stoichiometry Experiment in Chemistry class.  This is a 60 point grade, due in your notebook ON THURSDAY! 

 NO EXCEPTIONS, DUE THURSDAY, THURSDAY, THURSDAY, THURSDAY.

By  tomorrow (Tuesday, 5/15), you must have a - e done.   PLEASE follow directions. 

Reminder for the procedure that you need to write....you are trying to make and measure sodium acetate (in a 250 mL flask) out of sodium bicarbonate (baking soda) dissolved in a small amount of water and acetic acid.  We will know the reaction is done when it stops bubbling by adding enough acetic acid.  Then you will boil away the excess reactants and other products to be left with sodium acetate in the flask.  We want the mass of the sodium acetate. 

There are three important pieces of data to include in the data table. 

STOICHIOMETRY

CHEMISTRY:  Friday, 5/11, there will be a quiz on REACTIONS and STOICHIOMETRY.  Below are any "notes" we've taken and answers to ALL the practice problems we have done.
