Classification of Matter

1.  Arrange the following words into a concept map (tree diagram) showing an arbitrary arrangement of matter. The words are: pure substance, base solutions, elements, metals, nonmetals, matter, ionic, salt solutions, homogenous, compounds, mixtures, alloys, acid solutions, molecular, heterogeneous

2.  With examples, explain the difference between an element and a compound.

3.  With examples, explain the difference between a homogeneous and heterogeneous mixture.

4.  What does exothermic and endothermic mean? Give an example of each.

5.  (a) Chemical changes are identified by up to five (5) criteria. Name them.

(b) Provide 4 examples of a chemical change. (ie – wood burning)

6.  Explain what is meant by a physical change and give 4 examples.

7.  Draw a cartoon depicting the two (2) forms of energy. The cartoon must be different than “Marvin the Mole” from your handout! J

Chemical Complexities

1.  List five (5) factors that you should consider when naming or balancing the formula of a substance.

2.  Explain the difference between the “Classical System” and the “Stock System” as it relates to the naming of ionic compounds.

3.  (a) What is the group name that is given to the elements found in group 7 of the periodic table? (b) What is unique about these elements?

4.  Circle one. S2 is a gas solid

S8 is a gas solid

P2 is a gas solid

P4 is a gas solid

5.  Name:
