YOUR GRADES.
Nerst Equation - correct answer -Delta G= -nfecell
Nonspontaneous electrochemical reaction - correct answer -Ecell
<0
Spontaneous electrochemical reaction - correct answer -Ecell > 0
Students t test - correct answer -compares two means from two
different samples
Compare t to alpha
Determinate error (systematic error) - correct answer -Sampling,
method, measurement or personal errors. Can be traced to a
source. Affect accuracy.
, Page | 2
Indeterminate error (random error) - correct answer -Affect
precision. Can be traced to sample collection, manipulation and or
measurement.
Uncertainty - correct answer -The range of possible values for a
measurement. Can be added or subtracted via squaring each
standard deviation, performing the necessary operations (+,-) and
taking the square root.
Relative uncertainty - correct answer -Uncertainty of a quantity
divided by the value of the quantity. It is usually expressed as a
percentage of the measured quantity.
Multiplying or dividing uncertainty - correct answer -use relative
uncertainty. Square, add, then square root. Absolute uncertainty
can be obtained by multiplying by R.
Binomial Distribution - correct answer -The probability distribution
of X with parameters n and p. Homogenous mixtures.
