the
relative atomic mass
is
average mass
of
atoms
in an
element
, taking into account
mass
and
abundance
of its
isotopes.
the
relative formula mass
is the sum of
relative atomic masses
of all
atoms
in the
formula.

the
atom economy
is the measure of the amount of starting materials that end up as useful products.
the limiting reactant is the
reactant
that is completely
used
up
first and therefore
limits
the amount of
products
formed.
thermal
decomposition
is the reaction that occurs when heat is applied to a compound causing it to break down into its different chemical constituents.
