  1. Did you get a reaction? You know that a reaction took place if: ___________________:

  2. Did you get a reaction? You know that a reaction took place if: _________________________________________:

  3. Did you get a reaction? You know that a reaction took place if: ______________________________________:

  4. Did you get a reaction? You know that a reaction took place if: _______________________________________:

  5. Did you get a reaction? You know that a reaction took place if: A gas is released: A solid is formed: A permanent color change: A change in heat:

  6. Chemical Equations (aq) A (s) + B (aq)  C (l) + D (g) + E

  7. Chemical Equations Solid Solid Solid Gas Gas Gas Liquid Liquid Liquid Aqueous Aqueous Aqueous Aqueous means ______________________ (s) = solid = liquid (l) = gas (g) = aqueous (aq)

  8. Types of reactions • Decomposition

  9. Types of reactions Predictable decompositions:

  10. Types of reactions Predictable decompositions: metal carbonates with heat

  11. Types of reactions Unpredictable decompositions: metal oxides with heat metal oxide

  12. Types of reactions Unpredictable decompositions: metal ___ates with heat metal ___ate

  13. Types of reactions • Combination

  14. Types of reactions Predictable combination reactions: non-VOS metals and non-metals

  15. Types of reactions Unpredictable combination reactions: VOS metals and non-metals

  17. Types of reactions • Combustion

  18. Types of reactions • Single Replacement

  19. Activity Series ___________________________ Li > K > Ba > Sr > Ca > Na > Mg > Al > Mn > Zn > Fe > Cd > Co > Ni > Sn > Pb > (H) > Cu > Ag > Hg > Au Mg(s) + CdCl2(aq)

  20. Activity Series More active will react! Li > K > Ba > Sr > Ca > Na > Mg > Al > Mn > Zn > Fe > Cd > Co > Ni > Sn > Pb > (H) > Cu > Ag > Hg > Au AuNO3(aq) + Ag(s)

  21. Activity Series More active will react! Li > K > Ba > Sr > Ca > Na > Mg > Al > Mn > Zn > Fe > Cd > Co > Ni > Sn > Pb > (H) > Cu > Ag > Hg > Au Sr(ClO3)2(aq) + Al(s)

  22. Activity Series More active will react! Li > K > Ba > Sr > Ca > Na > Mg > Al > Mn > Zn > Fe > Cd > Co > Ni > Sn > Pb > (H) > Cu > Ag > Hg > Au ___________________ Cu(s) + HClO4(aq)

  23. Activity Series More active will react! Li > K > Ba > Sr > Ca > Na > Mg > Al > Mn > Zn > Fe > Cd > Co > Ni > Sn > Pb > (H) > Cu > Ag > Hg > Au HNO3(aq) + Pb(s)

  24. Activity Series More active will react! ________ ^ Li > K > Ba > Sr > Ca > Na > Mg > Al > Mn > Zn > Fe > Cd > Co > Ni > Sn > Pb > (H) > Cu > Ag > Hg > Au _______________________________ Ca + H2O H2SO4 + Hg Mn(C2H3O2)2 + K
