Review Game!
9. Many acids come from chemical
supply companies in specially-coated
glass bottles with extra-thick walls.
What is the most likely characteristic of
an acid that requires a special
container?
A. strong smell
B. corrosive nature
C . dark color
D. sour taste
B
The corrosive nature of an acid requires careful
packing so that it cannot dissolve the bottle or allow
the bottle to be broken, easily releasing the acid.
10. Which of the following phases of
matter has a definite size and shape?
A. gas
B. liquid
C. solid
D. all of these
C
3. Examine the table below

B. baking soda
C. grapes
D. apple juice
A
4. A compound is added to a solution of
hydrochloric acid, and the solution is
observed to see if a reaction takes
place. Chemical ___________ is being
tested.
A. acidity
B. reactivity
C. durability
D. solubility
B
Chemical reactivity tests determine if a substance
reacts with certain chemicals. One typical chemical
reactivity test involves adding the substance to a
solution of acid to see if a chemical reaction occurs.
Other common tests involve observing the reaction
between the unknown substance and oxygen, water,
or salts.
5. Which of the following items would
have the lowest density?
A. A 2 cm3 block of lead with a mass of
11 grams
B. A 12 cm3 block of wood with a mass
of 3 grams
C. A 6 cm3 block of ice with a mass of
4 grams
D. A 12 cm3 block of aluminum with a
mass of 2 grams
D
. Density refers to the mass per volume of an object.
A 2 cm3 block of wood with a mass of 11 grams has a density of
5.5 g/cm3.
A 12 cm3 block of wood with a mass of 3 grams has a density of
0.25 g/cm3.
A 6 cm3 block of ice with a mass of 4 grams has a density of
0.6667 g/cm3.
A 12 cm3 block of aluminum with a mass of 2 grams has a
density of 0.1667 g/cm3.
Therefore, a 12 cm3 block of aluminum with a mass of 2 grams
has the lowest density.
