(k = 8.988 x 109 N-m 2/C 2) correct answers where k is Coulomb's constant
(e = 1.6 X 10~19 C) correct answers The smallest possible unit
of charge is one electron unit
An electric field is defined as the electrostatic force per unit charge. The symbol for any
electric field is E and is vector and have units of N /C
or V/m correct answers what is E
E=kq/r^2 correct answers For a point charge, the electric field is found by dividing Coulomb's
law by q,
giving:
F=qE correct answers the force on a charge (q) in an electric field (E) is
u=qEd correct answers the potential energy (LJ) of a charge in an electric field
V=Ed correct answers Voltage ( V) is the potential for work by an
electric field in moving any charge from one point to another.
a chemical process that introduces a hydroxyl group (-OH) correct answers hydrolation
In organic chemistry, redox reactions look a little different. Electrons in an organic redox
reaction often are transferred in the form of a hydride ion - a proton and two electrons. correct
answers Oxidation and reduction
carboxylic acid group is produced by treating a substrate with carbon dioxide
Carboxylic acid added next to the oh- correct answers carboxlation
Velocity of ions depends on the ion mass-to-charge ratio fastest ions are those with smallest m/z
ratio correct answers Which experimental feature of the MALDI-MS technique allows the
separation of ions formed after the adduction of tissue molecules?
when one of the answers divided by 2 it must equal one of the answers with the same power
correct answers Which laser is suitable for the MALDI technique after its frequency is doubled?
Hydrolysis
this is because the passage talks about proteolytic cleavage which is hydrolysis correct answers
Proteins can be "fingerprinted" using MALDI if they are subjected to proteolytic cleavage before
analysis. During protein fingerprinting, what reaction occurs to prepare the sample for analysis?
,radiation frequency
E=hv
h=planks constant
v=radiation frequecny correct answers photon energy is directly proportional to
Based on the ray diagram and distances shown in Figure 1, the focal length of the lens is:
have a higher frequency than laser type C.
because the photon energy must be larger than the bond energy in order to break the bond.
Because the photon energy is directly proportional to the radiation frequency, laser type A must
have a higher frequency than laser type C. correct answers According to the passage and the data
in Table I, what feature must distinguish laser type A from laser type C in order to be suitable for
the cleavage of the bonds specified? Laser type A must:
Laser A has a higher enthalpy then Laser C
kinetic energy of a photoelectron is equal to hf - 3.4 eV = 20.5 eV - 3.4 eV = 17.1 eV.
E=hf-w correct answers What is the kinetic energy of a photoelectron produced in the energy
meter of the PAC device when the frequency of an incident photon that is NOT absorbed in the
solution is f = 5.0 × 1015 Hz?
alcohol produces the most stable carbocation (tertiary) and consequently will most easily lose a
water molecule upon protonation of the hydroxyl group in acidic media.
SN1, that's favored by a tertiary carbon or a secondary carbon, is going to be favored by SN1.
Whereas a methyl carbon or a primary carbon, that's going to probably go SN2. correct answers
Which alcohol will most likely undergo substitution by an SN1 mechanism in acidic conditions?
Add 0.1 M NaOH(aq) to quench unreacted anhydride. Then add diethyl ether and separate the
layers. The amide can be obtained from the ether layer by evaporating the solvent correct
answers Which extraction procedure will completely separate an amide from the by-product of
the reaction between an amine and excess carboxylic acid anhydride?
V=IR
minimum resistance = maximum current under constant voltage (V = IR) correct answers Ohm's
law
, Liposomes can be difficult to detect since they do not absorb visible light and many molecules
absorb UV light. The experimental design allowed fluorescent dye to be trapped inside during
liposome formation, which allowed their detection by fluorescence spectroscopy correct answers
Why did the liposomes fluoresce during size-exclusion chromatography?
CO2 correct answers Which cation is most likely to be found in place of Fe(II) in the square
planar binding domain of hemoglobin?
Co 2+ correct answers Which cation is most likely to be found in place of Fe(II) in the square
planar binding domain of hemoglobin?

catalysts correct answers types of enzymes
Transferases correct answers catalyze group transfer reactions. The transfer occurs from one
molecule that will be the donor to another molecule that will be the acceptor. Most of the time,
the donor is a cofactor that is charged with the group about to be transferred. Example:
Hexokinase used in glycolysis.
Hydrolases correct answers catalyze reactions that involve hydrolysis. This cases usually
involves the transfer of functional groups to water. When the hydrolase acts on amide, glycosyl,
peptide, ester, or other bonds, they not only catalyze the hydrolytic removal of a group from the
substrate but also a transfer of the group to an acceptor compound. These enzymes could also be
classified under transferases since hydrolysis can be viewed as a transfer of a functional group to
water as an acceptor. However, as the acceptor's reaction with water was discovered very early,
it's considered the main function of the enzyme which allows it to fall under this classification.
For example: Chymotrypsin.
Lyases correct answers Catalyze reactions where functional groups are added to break double
bonds in molecules or the reverse where double bonds are formed by the removal of functional
