  1. Why Is Electrochemistry Important? Chevy Volt

  2. cellular respiration

  3. photosynthesis

  4. alcohol metabolism

  5. Oxidation-Reduction(REDOX) Reactions 1. Reaction with oxygen e.g. CH4 + 2 O2 CO2 + 2 H2O methane ice

  6. 2. Transfer of electrons OXIDATION (loss of electrons) e.g. (s) Zn 2+(aq) + 2 e – (aq) + 2 e -  Cu (s) Zn (s) + Cu 2+(aq)  Zn 2+(aq) + Cu (s) Zn Cu 2+ REDUCTION (gain of electrons) oxidizing agent: substance that is being reduced reducing agent: substance that is being oxidized

  8. Oxidation Number A positive or negative number that corresponds to the apparent net electric charge that an atom would have if electron pairs in covalent bonds belonged entirely to the more electronegative atom. Rules for Assigning Oxidation Numbers • F is ALWAYS -1. • 2.H is almost always +1, except when found in metal hydrides. • e.g. Li H • +1 -1 3.O is almost always -2, except where rules 1 & 2 would be violated. e.g. O F2 H2 O2 +2 -1 +1 -1
