2)
Test #2 – Thur. Oct. 17th- Target
Concepts on-line- ½ page of notes
front side only done by hand
3)
Density – Due on Friday – Oct. 18th

3. 1)
Name any of the methods for finding
volume.
2)
What three unit labels for volume
are equivalent.
3)
If I know the volume and the density
of a substance, how do I find the
mass?
4)
What vocabulary word describes
when CO2(s) changes to CO2(g)?

4. 5)
What is the density formula?
6)
Separating the salt from salt water
is a physical change. What
vocabulary word describes how I
would do this?
7)
Why is photosynthesis a chemical
change?
8)
Physical or Chemical: Deposition of
gas to ice.

5. 9)
10)

experiment would be displayed on
which axis on a graph?
CO2(s) + energy
CO 2(g) :
chemical or physical?
11)

cannot be created or destroyed, just
rearranged?

6. 12)
What kind of changes do not result in the
production of new substances?

14)
If I give you a “golden” coin, how could
you find out if it was real gold?
15)
A direct relationship between the
independent and dependent variable
would produce a graph that looked like?

7. 1) Identify which number values you have
by looking at the unit label (mass,
volume or density?)

8. Mass UNIT
GRAM or any form
of gram…kg, cg,
mg
Volume UNIT
mL, cc, cm3, m3
L
Density UNIT
Combination unit
g/mL, g/cc, g/cm3
mass
volume

9. 2) Place each number into their correct
place in the triangle.
Mass
Number
Density
Number
Volume
Number

10. 3. If you have a top and bottom variable in the
triangle – DIVIDE (numerator by denominator)
to find the missing variable.
If you have the two variables on the bottom –
MULTIPLY them to find the top variable.
Mass
Number
divide
Density
Number
Volume
Number
multiply

11. 1.
Complete all the problems by
showing your work.
2.
Hint: If the problem is worth more
than 5 points you may have to:
1) Solve for Volume First, then
Solve for Density
2) Answer a question as well
