What does Q mean with respect to Ksp?
Q is the reaction quotient and is used for solutions that are not in equilibrium.
How many periods are on the periodic table(If you look, it's -200 points)?

What does the term for kcat in the Michaelis Menten equation mean and what does it represent?
kcat is the turnover number and it represents the number of substrate molecules converted to product in a certain time.
Which salt is more soluble:

Ca(OH)2(s) Ksp= 6.5x10-6
Ce(OH)3(s) Ksp=6.0x10-22
You're doing great!!
Which of the following is not a physics property of metals?
-Luster, Corrosion, Malleability, Ductile
Corrosion
What is autoprotolysis?

What 4 factors determine whether a process will proceed via Sn1 or Sn2?
1. Substrate
2. Nucleophile
3. Leaving Group
4. Solvent
How many steps are different between glycolysis and gluconeogenesis?
Just 3...
What is the difference between IR and Raman active molecules?
IR active molecules have a double bond, free electrons, and have asymmetric symmetry.
Raman active molecules have symmetric stretching and are more polarizable.
What are the elements on the zig zag line called?
Metalloids
Rank the following in order of least acidic to most acidic and explain why this trend occurs:
- HBrO, HBrO2, HBrO3, HBrO4
HBrO < HBrO2 < HBrO3 < HBrO4
The electron density shifts to the oxygens making it easier to deprotonate the H.
How do you add H2O anti-Markovnikov onto a triple bond(include reagents)?
- Hydroboration Oxidation
-BH3*THF
- H2O2, NaOH
Acetyl CoA is the starting material for what major process?
Citric Acid Cycle

When was the periodic table invented, and by whom?
1869 by Dimitri Mendeleev
This is the 150th Anniversary of the Periodic Table!!!!!
