Honors Chemistry Final Questions? Needz Immediate Response.
« on: January 20, 2010, 08:49:13 PM »
Alright Im reviewing for my Chem Final tmo and writing down some key notes for tmo.
Questions..
1. Solved
2. Molecular Formula?
   A. Something to do with using the Empirical Formula with it?
3. How to Figure Isotopes fast.
4. Converting Complex?- Pretty sure i know it, just weirdly worded.
5. Theoretical, Percent and Actual Yield-- with stoichiometry
6. Finding Limiting and Excess Reactants.

Thank you for the help. :)

Theoretical yield is the stoichometric amounts (never this!)
Actual Yield is, well.. actual yeild in the reaction
Percent yield is Actual over theoretical yields

Example: I got 7.5 grams of product. I should have gotten 10 grams according to the formula. My percent yield is 7.5/10=75%
