Significant Figures Rules - answer 1) All nonzero
digits are significant (not true; can be broken up
into subatmoic particles [protons, neutrons, &
electrons])
2) Interior zeroes (zeroes between 2 non-zero
digits) are significant (not true because of
isotopes)
, 3) Leading zeroes (zeroes to the left of the first
non-zero digit) are not significant
4) Trailing zeroes (zeroes at the end of a number)
are categorized as follows:
-Trailing zeroes after a decimal point are always
significant
-Trailing zeroes before a decimal point (and after a
non-zero number) are always significant
-Trailing zeroes before an implied decimal point are
ambiguous and should be avoided by using
scientific notation
Dalton's Atomic Theory - answer 1) Each element
is composed of tiny, indestructible particles called
atoms
2) All stoms of a given element have the same
mass and other properties that distinguish them
from the atoms of other elements
3) Atoms combine in simple, whole-number ratios
to form compounds
4) Atoms of one element cannot change into atoms
of another element. In a chemical reaction, atoms
only change the way that they are bound together
with other atoms
Precision - answer How reproducible; how close
the measurements are to each other
