3. Why is flammability a chemical property, but boiling point and melting point are physical
properties? Explain yourself completely, using the definitions of physical and chemical
properties to support your answer (use extra paper if necessary):
LG3 Learning Goal 4: Classify matter (element, molecule/compound, or mixture).
4. List at least two major differences between compounds and mixtures:
LG4 5. Listed on the periodic table, the simplest substance that cannot be broken down chemically into
other substances is called a(n)
. The basic particle that this substance is made
up of is called a(n)
.
6. In a molecule or compound, atoms are held together by forces of attraction called
.
7. Salt water is an example of a
mixture because it looks the same
throughout since it is so evenly mixed. Sand and water is an example of a
mixture because you can see the different parts.
LG4 8. Indicate whether each substance below is an element, a molecule and/or a compound, or a
mixture by placing a check mark in the correct box(s). You can have a check mark in more than
one box.
