100
This is the energy transferred between a system and its surroundings as a result of a temperature gradient.
What is heat?
100
This is the process of gaining electrons.
What is reduction? (The cathode is also accepted... half points if option is available)
100
This intermolecular force is present in every substance.
What are London (dispersion) forces?
100
Gamma.
What is the activity coefficient (for our purposes we assume it is 1)?
100
This is the amount of energy required to ionize a metal atom.
What is the work function?
200
This is independent of the mechanism towards a set of conditions.
What is state function?
200
The standard cell potential is positive.
What is spontaneous?
200
This functional group is a cyclic amide.
What is lactam?
200
This occurs when Q < K.
What is shift forward?
200
Fluorine has the highest magnitude of this.
What is eletronegativity? or What is electron affinity?
300
In a bomb calorimeter, this is zero (usually).
What is work?
300
This is equal to -z*F*E(cell).
What is Gibbs energy change?
300
As this increases, so does the strength of London (dispersion) forces.
What is polarizability (the tendency for charge separation to occur)?
300
At very low concentrations, this must be taken into consideration.
What is the auto-ionization of water?
300
This is the angle between N-H in NH3.
What is <109.5 degrees (non-ideal)?
400
The standard enthalpies of these entities are zero.
What are pure elements?
400
This is a cell in which the standard cell potential is zero.
What is a concentration cell?
400
C6H14 (name 3).
What are: hexane, 2-methylpentane,3-methylpentane? 2,2-dimethylbutane, or 2,3-dimethylbutane?
400
HOF/HOCl. This is the stronger acid.
What is HOF?
400
This occurs when Ksp is very small.
What is precipitation?
500
The standard enthalpy of formation of [OH-]. Given that: H+ (aq) + OH- (aq) -> H2O (l) Standard Enthalpy= -55.8 kJ.
What is -230.0 kJ/mol of OH-?
500
This is the balanced chemical equation of gaseous chlorine producing aqueous chloride and aqueous chlorate in acidic solution.
What is 3Cl2(g) + 3H2O(l) -> ClO3-(aq) + 5Cl-(aq) + 6H+(aq)?
500
These are the four criteria for aromaticity.
What are: cyclic, conjugated sp2 system, Huckel's number of electrons (4n+2 pi electrons), and planar?
500
This allows us to avoid the quadratic equation.
What is the small x assumption? or What is a perfect square?
500
This is the type of bond between hydrogen and fluorine.
What is polar covalent?
