  1. TYPES OF CHEMICAL REACTIONS

  2. There are FIVE main types of chemical reactions • Synthesis Reaction • Decomposition Reaction • Single Replacement Reaction • Double Replacement Reaction • Combustion Reaction

  3. Synthesis Reactions Two reactants combine to form ONE product • “Addition” reaction General format: A + B AB EX: Al + O2 Al2O3 Na + Cl2NaCl

  4. Soap Opera Version“Going Out”  +

  5. Decomposition Reactions ONE reactant breaks down into two or more products • Opposite of synthesis General Format: AB A + B EX: KClO3KCl + O2 MgO Mg + O2

  6. Soap Opera VersionThe “Break-Up”  +

  7. Single Replacement Reactions One ELEMENT replaces another element in a compound General Format: A + BCAC + B EX: Ca + Ag(NO3)Ag + Ca(NO3)2 Fe + CuCl2FeCl2 + Cu

  8. Soap Opera Version “The Home Wrecker”  + +

  9. Double Replacement Reactions TWO compounds produce two NEW COMPOUNDS • The positive ions replace each other General Format: AB + CDAD + CB EX: NaCl + KBrNaBr + KCl K(OH) +Pb(NO3)2 K(NO3)+Pb(OH)2 H3(PO4) +K(OH)K3(PO4) + H2O

  10. Soap Opera Version “Wife Swap ”  + +

  11. Combustion Reactions A HYDROCARBON (contains hydrogen and carbon and sometimes oxygen) combines with OXYGEN to form CARBON DIOXIDE and WATER General Format: CXHY + O2CO2 + H2O EX: CH4 + O2CO2 + H2O

  12. Your Turn!! synthesis Ca + O2 2 CaO Br2 + LiILiBr + I2 Al + Fe(NO3)2 Al(NO3)3 + Fe MgO + HCl MgCl2 + H2O C4H10 + O2 CO2 + H2O single replacement single replacement double replacement combustion

  13. Your Turn!! decomposition H2O2 H2O + O2 (NH4)3(PO4) + Sr(OH)2 Sr3(PO4)2 + (NH4)(OH) H2(SO4) + Na(OH)  Na2(SO4) + H2O Zn + Ag(NO3)  Zn(NO3)2 + Ag Cu(NO3) + KCl K(NO3) + CuCl double replacement double replacement single replacement double replacement
