1. organic

   • carbon compounds
     • crude oils
     • alkanes
     • fractional distilations
     • cracking alkenes
     • burning hydrocarbons
       • abundance of o2
         • produce CO2 and H2O
       • limited o2
         • produces CO and H2O
       • not enough o2
         • produces CO and H2O
   • alkenes and alcohols
     • alkenes
     • alkene reactions
     • alcohols

2. bonding

   • metalic
   • covalent
     • sharing electron
       • in group 5 - 7
   • ionic
     • electrolysis
       • cathode
         • attracts cations
       • anode
         • attracts anions
       • used to extract ores more reactive than carbon
     • metal bonding with non-metals
     • cations
     • anions
     • reacting with carbon
       • used to extract ores less reactive than carbon

3. moles

4. endo / exo

   • endo
     • reactants have more energy than products
     • released energy ad the reaction progresses
   • exo
     • absorbs energy as reaction proggresses
     • products have more energy than reactants
