MCAT Exam 3 Practice Questions
and Answers (Graded A)
capacitance equation with charge - ANSWER - C= Q/V
doppler effect - ANSWER - states that the frequency that the person on the railcar
hears before passing the horn is larger than the actual frequency of the sound
emitted and hears a lower frequency than the actual one once the person passes
the horn
an increase (or decrease) in the frequency of sound, light, or other waves as the
source and observer move toward (or away from) each other
dielectric materials - ANSWER - do not conduct electricity
when asked about how much power or force you need to keep a cart going, think
about - ANSWER - FRICTION
the thermodynamic stability of isomeric organic compounds can be inferred using
which data? - ANSWER - heats of combustion
- if it produces a lot of heat when combusted, then more unstable
period for voltage source - ANSWER - the time it takes to complete a full cycle
delta G 'o - ANSWER - -RTln(Keq)
Keq - ANSWER - prod/reactants
Ksp - ANSWER - [ion][ion]
GLUCOSE important parts? - ANSWER - THE OH bonds~ h bonding is possible
, dehydration reaction - ANSWER - adds double bond across?? PUT MORE HERE
if Kb > Ka then characterized as? - ANSWER - BASE, if opposite then acid
if the electric field is UNIFORM between the electrodes, it means that the electric
field lines? - ANSWER - are equally spaced at both electrodes and between them
When two amino acids are joined via a peptide bond, what is the mass of the
byproduct of this reaction? - ANSWER - H2O is produced as the byproduct and it has
a mass of 18amu -- REMEMBER amu is same as g/mol
acetylation? - ANSWER - addition of an acetyl group, (RC=O)-- you can also have
deactylation
if pH is 8, what is the concentration of hydroxide ions? - ANSWER - 10^-6
porphyrin? - ANSWER - With a total of 26 π-electrons, of which 18 π-electrons form a
planar, continuous cycle, the porphyrin ring structure is often described as
aromatic.[1][2] One result of the large conjugated system is that porphyrins
typically absorb strongly in the visible region of the electromagnetic spectrum, i.e.
they are deeply colored
basic unit is the pyrrole ring which is a five sided heterocycle with one nitrogen
atom
pK = ? - ANSWER - the pH at which the fraction of folded DNA is 0.5
ionization energy is higher - ANSWER - if youre closer to the nucleus
WHICH PROPERTY OF WAVES REMAINS UNCHANGED as it passes through any
medium? - ANSWER - FREQUENCY
