  1. Classification of Chemical Reactions: The Soap-Opera of Chemistry

  2. 5 Main types of reactions Synthesis- “Love at first sight” • Decomposition- “The big break-up” • Single Replacement- “My best friend’s girlfriend” • Double Replacement- “Revenge” • Combustion- “The playa”

  3. Synthesis- “Love at first sight” I like your hat Hey Harry Can I get your number? I like your braces! Hey Sally Basic equation: A+B --> AB

  4. Synthesis- “Love at first sight” • The compound produced is larger and more complex than the reactants • Element/compound + Element/Compound = Large Compound • Example: H2 + O2 ---> H2O

  5. Decomposition- “The Big Break-up” I was washing my hair. Whatever! We are through! Where were you last night? I don’t believe you I’m leaving! But, baby I love you! • Basic Equation: AB --> A+B

  6. Decomposition- “The Big Break-up” I am so over you • The Breakdown of a larger compound • Example: 2 H2O --> 2 H2 + O2

  7. Single Replacement- “My Best Friend’s Girlfriend” This Sucks! Hey Mark, here comes your friend Pierre! Oh Pierre! Mark I’m leaving you! Hey, Baby. How you doing? Man, Mark’s Girl is pretty HOTT! Basic Equation: AX + B --> BX + A

  8. 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) • Cations always replaces cations and anions always replace anions • Example: 2K + 2HCl --> 2KCl + H2 • (K is more reactive than H)

  9. Double Replacement- “Revenge” Chloe was my one true love, but Mark’s girl is looking pretty HOTT! I can’t believe Chloe would do that! I have to get Pierre back. Hey Chloe do you want to go out? But Chloe I love you, I can’t live with out you!!! Of course! Hey Baby Pierre, I’m so sick of you! Oh Pierre! Basic Equation: AX + BY --> AY + BX

  10. Double Replacement- “Revenge” • One element in each compound switches places with the other element in the other compound • Always involves the formation of a molecular compound such as water (Tears) and either a precipitate or a gas • Example: 2 KI(aq) + Pb(NO3)2(aq)--> PbI2(s) + 2 KNO3(aq)

  11. Combustion- “The playa” That was a great date! Who’s that HOTTIE? Ashley you’re my BFF!! Hey Ladies!! How you doin? Baby, I love you! (3 weeks later) BLING! Basic Equation: AB + O --> AO + BO

  12. Combustion- “The player” Honey, Why is Ashley’s number on your phone? • Oxygen is the playa • Produce oxide compounds and energy (very exothermic) • Example: CH4 + 2O2--> CO2 + 2H2O + ENERGY

  13. Your Assignment Create a Reaction Comic Book Must Contain all 5 types of reactions and have pictures and captions Must include name of reaction and a real example Needs to include color Does not have to be hand drawn
