Exam Questions and Answers
Arrhenius acids --- correct precise answer ---ionize in water
to give H+ ions
Arrhenius bases --- correct precise answer ---ionize (or
dissociate) in water to give OH− ions
,bronsted acids --- correct precise answer ---donate protons
(H+ ions)
bronsted bases --- correct precise answer ---accept protons
neutralization reaction --- correct precise answer ---reaction
of an acid and base
products are water and a salt
oxidizing agent --- correct precise answer ---gets reduced
reducing agent --- correct precise answer ---gets oxidized
Beer-Lambert law --- correct precise answer ---relates the
absorbance of a solution to its concentration and the path
length through which the light passes
titration --- correct precise answer ---involves an acid-base
reaction
Typically, a solution of known concentration (a standard
solution) is added gradually to a solution of unknown
concentration with the goal of determining the unknown
concentration.
equivalence point --- correct precise answer ---The point at
which the reaction in the titration is complete
,indicator --- correct precise answer ---a substance that
changes color at or near the equivalence point of a titration
endpoint --- correct precise answer ---The point at which the
indicator changes color
Mc × Lc = Md × Ld --- correct precise answer ---volume of
concentrated solution is diluted
moles of solute before dilution = moles of solute after dilution
--- correct precise answer ---
Mc × mLc = Md × mLd --- correct precise answer ---
T = I / I0 --- correct precise answer ---In absorption
spectrophotometry, transmittance (T) is equal to the ratio of
transmitted light (I) to incident light (I0).
A = -logT = -logI/I0 --- correct precise answer ---Absorbance
(A) is equal to minus the log of transmittance.
A = etc --- correct precise answer ---The Beer-Lambert law is
used to determine concentration from absorbance (A), molar
absorptivity (e), and path length (b) through the sample.
Energy --- correct precise answer ---the capacity to do work
or transfer heat
, kinetic energy --- correct precise answer ---energy of motion
Ek = 1/2 mu^2
m=mass
u=velocity
thermal energy --- correct precise answer ---energy
associated with the random motion of atoms and molecules
potential energy --- correct precise answer ---energy
possessed by an object by virtue of its position
chemical energy --- correct precise answer ---energy stored
within the structural units (molecules or polyatomic ions) of
chemical substances
electrostatic energy --- correct precise answer ---potential
energy that results from the interaction of charged particles
Law of Conservation of Energy --- correct precise answer ---
When energy of one form disappears, the same amount of
energy must appear in another form or forms
Thermochemistry --- correct precise answer ---the study of
heat changes in chemical reactions
joule (J) --- correct precise answer ---SI unit of energy
Kelvin --- correct precise answer ---SI unit for temperature
