Soap-Opera of
Chemistry
5 Main types of reactions
• Synthesis- “Love at first sight”
• Decomposition- “The big break-up”
• Single Replacement- “My best
friends girlfriend”
• Double Replacement- “Revenge”
• Combustion- “The player”
Synthesis- “Love at first sight”
I Ilike
like
Can I get
your
your
Hey
your
braces
hat
Harry
number
Hey
Sally
Basic equation: A+B
AB
Synthesis- “Love at first sight”
The compound produced is
larger and more complex than
the reactants
•
Example: CO2 + 6 H2O
C6H12O6 + 6 O2
I was
Whatever
washing
my hair
Decomposition- “The Big
Break-up”
We are
Where
But, baby I
I don’t
Im leaving
were
you love you
believe you
last night
Basic Equation: AB
Through
A+B
Decomposition- “The
Big Break-up”
I am so
over you
•The Breakdown of a larger
compound
Example: 2 H2O
2 H2 + O2
Single Replacement- “My Best
Friends Girlfriend”
Hey, Baby.
This
Hey Mark, here comes How you
Oh Pierre! Mark
your friend Pierre
doing?
Im leaving you
Basic Eqn: AX + B
Man, Marks
Girl is pretty
Hot!
Stinks!
BX + A
Single Replacement- “My Best
Friends Girlfriend”
•“Free” element must be the more reactive
element for a reaction to occur ( Pierre is
more suave then Mark)
• The further apart 2 elements are on the
activity series, the more likely the higher
one will replace the lower one in a
compound.
• Example: 2K + 2HCl
2KCl + H2
Double ReplacementI have to get Pierre
can’t
“Revenge” Ibelieve
back. Hey Chloe do you
want to go out
Pierre, Im
sick of you
Ok
Chloe would
do that
Chloe was my one
true love, but Marks
girl is looking pretty
Hot.
Basic Eqn: AX + BY
AY + BX
Double Replacement“Revenge”
• Always
involves the formation of a
molecular compound such as water (Tears)
and either a precipitate or a gas
Ex: 2 KI(aq) + Pb(NO3)2(aq)
PbI2(s) + 2 KNO3(aq)
Combustion- “The player”
Ashley you’re
my BFF
Hey Ladies
That was a
great date
Baby, I
love you
(3 weeks later)
Basic Eqn: AB + O
AO + BO
Combustion- “The player”
Honey, Why is
Ashley’s number
on your phone?
Produce oxide compounds
and energy (very exothermic)
•
Ex: CH4 + 2O2
CO2 + 2H2O + ENERGY
