 Is
“breaking apart” an endothermic or
exothermic step? Why
Answer
Answer: Making a Solution –
400
 Endothermic.
Energy must be added to
the chemical to force the particles apart.
Back to the
Game!
Making a Solution - 500
 Is
making new bonds endothermic or
exothermic? Why?
Answer
Answer: Making a Solution –
500
 Exothermic;
The energy that was required
to hold the particles apart is no longer
needed, so it is released.
Back to the
Game!
 Using
Hot Hands - 100
the data table below, identify which
substances were exothermic when they
dissolved. How can you tell?
Answer
Answer: Hot Hands – 100
 LiBr,
RbF; they caused the water’s
temperature to rise.

Game!
Hot Hands - 200
 Identify
which substances are
endothermic when dissolving, using the
data table. How can you tell?
Answer
Answer: Hot Hands – 200
 NaNO3,
KBr; both caused the water’s
temperature to drop.


Which of these 4 substances has particles that
are hardest to separate? How can you tell?
Answer
Answer: Hot Hands – 300

 Which
Hot Hands - 400
substance releases the most
energy, per gram, when dissolving? How
can you tell?
Answer
Answer: Hot Hands – 400
 LiBr;
Caused the temperature to rise the
same amount, but using less chemical.

Hot Hands - 500
 Predict,
what would happen if we added
5g of NaNO3 AND 5g of RbF to 100.0g of
water.
Answer
Answer: Hot Hands – 500
 The
final temperature would be around
22.5oC. They would cancel out.

Bonds & Forces - 100
 Describe
the strength of the bonds in a
molecular compound. Do they break in
when dissolving?
Answer
Answer: Bonds & Forces – 100
 Strong
bonds hold the elements together.
They do not break when dissolving, they
are too strong.
Back to the
Game!
Bonds & Forces - 200
 Describe
the strength of the bonds in an
ionic compound.
Do they break when dissolving?
Why/Why Not?
Answer
Answer: Bonds & Forces – 200
 Weak
attractive force; They only break if
the solute is more attracted to the solvent.

Game!
Bonds & Forces - 300
 NaCl
dissolves in water, but AgCl does
not. Why Not?
Answer
Answer: Bonds & Forces – 300
 The
attraction between Ag and Cl is
stronger than its attraction to water.

Bonds & Forces - 400
 Which
two elements are connect by a
stronger bond/force? How can you tell?
Cobalt Flouride (CoF2)
or
Xenon Tetrafluoride (XeF4)
Answer
Answer: Bonds & Forces – 400
 Xenon
Tetrafluoride (XeF4) is a molecular
compound.
 Cobalt Fluoride (CoF2) is an ionic
compound
 Since
molecular compounds have strong
bonds and ionic compounds do not, the
bonds in XeF4 are stronger

 Ammonium
Nitrate (NH4NO3) is an
example of an ionic compound that that
is made by combining the two molecular
compounds Ammonium (NH4+) and
Nitrate (NO3-). Draw a line “cutting” the
bonds that would break in water.
Answer
Answer: Bonds & Forces – 500
Only the Weak Attractive Force between
the two ions breaks.

we put too much Kool-Aid powder into
water it sinks to the bottom and doesn’t
all dissolve.
What can we do to the water to make it
all dissolve? Why?
Answer
Answer: Random! – 500
 Heat
it up! We need energy to break
apart the solute. Give it more energy,
and more will break up.
