• Single Replacement- Single Replacement- ““My best friendMy best friend’’s s girlfriend girlfriend””

• Double Replacement- Double Replacement- ““RevengeRevenge””

• Combustion- Combustion- ““The playaThe playa””

Synthesis- Synthesis- ““Love at first Love at first sightsight””

Basic equation: A+B Basic equation: A+B --> AB--> AB

Hey Harry

Hey Sally

I like your

braces!

Can I get your

number?

I like your hat

Synthesis- Synthesis- ““Love at first Love at first sightsight””

• The compound produced is larger and more The compound produced is larger and more complex than the reactantscomplex than the reactants

•Element/compound + Element/Compound = Large Element/compound + Element/Compound = Large CompoundCompound

• Example: H2 + O2 ---> H2O

Decomposition- Decomposition- ““The Big The Big Break-upBreak-up””

Where were you last night?

I was washing my hair.

I don’t believe you

Whatever!

I’m leaving!But, baby I

love you!

We are through!

Basic Equation: AB Basic Equation: AB --> A+B--> A+B

Decomposition- Decomposition- ““The Big The Big Break-upBreak-up””

•The Breakdown of a larger The Breakdown of a larger compoundcompound• Example: 2 HExample: 2 H22O --> 2 HO --> 2 H22 + O + O22

I am so over you

Single Replacement- Single Replacement- ““My Best My Best FriendFriend’’s Girlfriends Girlfriend””

Hey Mark, here comes your friend Pierre!

Man, Mark’s Girl is pretty HOTT!

Oh Pierre! Mark I’m leaving you!

Basic Equation: AX + B Basic Equation: AX + B --> BX + A--> BX + A

Hey, Baby. How you doing?

This Sucks!

Single Replacement- Single Replacement- ““My Best My Best Friends GirlfriendFriends Girlfriend””

•“Free” element must be the more reactive element for a reaction to occur ( Pierre is more suave then Mark)• Cations always replaces cations and anions always replace anions• Example: 2K + 2HCl --> 2KCl + H2

(K is more reactive than H)

Double Replacement- Double Replacement- ““RevengeRevenge””

Basic Equation: AX + BY Basic Equation: AX + BY --> AY + BX--> AY + BX

Pierre, I’m so sick of you!

But Chloe I love you, I can’t live with out you!!!

Chloe was my one true love, but Mark’s girl is looking pretty HOTT!

Of course!

I can’t believe Chloe would do that!

Hey BabyOh Pierre!

I have to get Pierre back. Hey Chloe do you want to go out?

Double Replacement- Double Replacement- ““RevengeRevenge””

•One element in each compound switches places One element in each compound switches places with the other element in the other compound with the other element in the other compound

•Always involves the formation of a molecular Always involves the formation of a molecular compound such as water (Tears) and either a compound such as water (Tears) and either a precipitate or a gasprecipitate or a gas

• Example: 2 KIExample: 2 KI(aq)(aq) + Pb(NO + Pb(NO33))2(aq)2(aq) --> PbI--> PbI2(s)2(s) + 2 + 2 KNOKNO3(aq)3(aq)

Combustion- Combustion- ““The playaThe playa””

Basic Equation: AB + O Basic Equation: AB + O --> AO + BO--> AO + BO

That was a great date! Baby, I

love you!

Hey Ladies!! How you doin?

Who’s that HOTTIE?

BLING!BLING!

Ashley you’re my BFF!!
