C2

1. Electrolysis

   • Reduction is receiving electrons
   • Oxidation is gaining electrons
   • The broken down substance is called the electrolyte

2. Ionic Bonding

   • High M.P and B.P
   • Conduct electricity when molten or dissolved in water

3. Covalent Bonding

   • Low M.P and B.P
   • Do not conduct electricity
   • Giant Covalent Bonds
     • Diamond (each carbon has 4 bonds)
     • Graphite (each carbon has 3 bonds)
     • Silicon Dioxide

4. Polymers and Nanoscience

   • Thermosetting polymers have crosslinks
   • 1 nanoparticle = 100 atoms
   • Nanoparticles are used in suncreens
   • M.P determined by strength of intermolecular forces

5. Percentage yeild= products/max possible products X 100

6. Acids and Bases

   • Acid + Metal = Salt + Hydrogen
   • Acid + Base = Salt + Water
