Chemistry - Coggle Diagram

- - - - rusting of metal
    - - explosion
  - - - a larger surface are will cause more particles to collide because the larger that surface area, the small the piece (volume)
    - - a higher temperature will cause particles to gain more kinetic energy and move around more, therefore more collisions happening
    - - If there are more particles to collide, there will be more collisions
    - - a catalyst is a substance that can speed up a reaction without being used up
      - it can speed a reaction up
- - - - oxygen
      - water
    - - paint
      - oil
      - electrosis
    - - to coat iron in zinc
      - to physically stop water and oxygen from touching the iron
      - If the zinc gets scratched it will still not rust because the zinc will react with nearby oxygen because it is more reactive (sacrificial method)
- - - - Metal chloride + hydrogen
