1. The living and
nonliving
components of the
earth contain
mixtures
…cont…..
Separation of Mixtures
Worksheet –
Methods of
separating mixtures
Gravimetric analysis
2. Although most
elements are found
in combinations on
earth, some
elements are found
uncombined.
3. Elements in
earth materials are
present mostly as
compounds
because of
interactions at the
atomic level.
5. The properties of
elements and
compounds are
determined by their
bonding and
structure.
