Ecell = cathode - anode when talking about standard reduction potentials. The -1.33 is the standard oxidation potential so if you want to use this formula you must make it positive first.

Other alkanes have more angle strain. Each C-C bond wants to be roughly 109.5 degrees. With less that 5 Carbons each C-C bond angle is too big (ex: cyclopropanes C-C bonds are at 120 degrees) and with more than 6 carbons the C-C bond angle is too small (ex: cyclooctanes C-C bonds would be 45 degrees...

It would go down the priority chain.

functional groups > double and triple bonds > halogens > alkyl groups

the pH of the solution is 2.0 and -log[H+] = pH so [H+] = 10^-2 = 0.01M

what is the difference between torsional strain and steric strain?

Towards the end of class Lavelle was talking about how H2O is a nucleophile because it has valence electrons on the O but that .. if i remember correctly .. HO2 was an electrophile because of polarization? I'm still very confused by this could someone explain again? Also, is OH a nucleophile or an e...

Chapter 4 Question 30 asks, the activation energy in an organic reaction if known to be 125 kj/mol. Will this reaction occur at room temperature. The answer is no but why?

When the system is irreversible S(surrounding) = 0 meaning S(system) = S(universe)

Sometimes Pt is added at the end or beginning of the cell diagrams. Is this only added when there isn't another solid or is there another way to know when to add it?

The gas constant, R, is multiplied by 5/2 to find C at a constant pressure. So you don't need to multiply C by 5/2

In Quiz 1 Prep Question 3 it asks: If 2.00 mol of an ideal gas at 300 K and 3.00 atm expands isothermally and reversibly from 6.00 L to 18.00 L and has a final pressure of 1.20 atm, what is w,q, and change in internal energy? I found w using w=-nRTln(V2/V1) but how do I find q without a change in te...

In the solution for problem 31 of chapter 8 it says the molar heat capacity of a monatomic ideal gas at constant pressure is C=5/2R and the molar heat capacity of a monatomic ideal gas at constant volume is C=3/2R. Where did the numbers 3/2 and 5/2 come from? Are these statements true for any problem?

Kendall_Chaffin_3C

These two numbers are different forms of the gas constant and would be given to you on the exam. They are also on the sheet of equations on the back of the periodic table given to you when you bought your course reader.

How do you tell if an oxide is acidic, basic, or amphoteric?

For example question 12.17 asks to state whether the following are acidic, basic, or amphoteric:
a. BaO
b. SO3
c. As2O3
d. Bi2O3

The optimist sees the glass half full. The pessimist sees the glass half empty. The chemist see the glass completely full, half in the liquid state and half in the vapor state. A proton and a neutron are walking down the street. The proton says, "Wait, I dropped an electron help me look for it....

Deprotonation is the the removal of a proton from an acid to form a conjugate base of that acid.

Hybridized orbits are lower in energy and therefore more favorable then unhybridized orbitals. So hybridization occurs to create more stable compounds.

In the book it says electron affinities are higher towards the right of the periodic table. But, group 15 elements have lower ionization energies then group 14. Why is this?

If the electron spin is +1/2 the arrow points up and if the election spin is -1/2 the arrow points down.

Question 8 states If one incorrectly assumed that an electron is located inside the nucleus of an atom, then for a hydrogen atom the electron is confined to its nuclear diameter of 1.7 x 10-15 m which would be the electron's uncertainty in position. Use the Heisenberg uncertainty equation to calcula...

Do we need to know how to name compounds for quizzes? If so what polyatomic ions should we memorize? Also do we need to be familiar with the solubility guidelines?
