STATION ANSWERS
STATION 1Front
1) Mixture-made of two or more pure substances together in the same place, but are not
chemically combined.
2) Two types of Mixtures-Heterogeneous and Homogeneous
3) Two parts of a solution-solute and solvent
4) CHARTa) Salt water- Homogenous (Solution)
b) Garden Salad-Heterogeneous (Mechanical)
c) Bag of different colored jelly beans-Heterogeneous (Mechanical)
d) Concrete- Homogenous (Solution)
e) Strawberry Ice cream with fruit-Heterogeneous
f) Instant Coffee-Homogenous (Solution)
5) Differences between hetero and homoHetero you can see the different parts and homo you cannot see the different parts
Back
1) A mixture is not a chemical combining of substances.
2) In a compound, the atoms are chemically combined so that the elements making up the
compound lose their identities and do take on new sets of properties.
3) The smallest identifiable unit of a compound is a(n) atom which is made up of elements that are
chemically bonded.
4) A mixture is always made up of combinations of elements. FALSE
5) In a mixture, the substances retain their identities.
6) In a mixture, the substances involved can be separated by a simple physical process. In a
compound, the elements involved cannot be separated by a physical process because the
elements are chemically combined.
7) An element can be broken down into a simpler substance. FALSE
8) The smallest identifiable unit of an elements is a(n) atom.
9) Elements are silver, oxygen, gold, sulfur, carbon, magnesium, nitrogen, chromium and nickel.
