  1. REDOXPart 2

  2. ROTTING!

  3. RUST!

  4. COMBUSTION!

  5. This is a redox process by which YOUR BODY STORES ENERGY.

  6. An oxidation-reduction reaction (redox for short) is:If you have one of these processes, you must have the other. Why?

  7. The number of electrons lost and gained in a reaction must be equal. What Law demands this?You can use this fact to help balance difficult equations.

  8. For example: the space shuttle was lifted off the earth by this tough redox reaction:NH4ClO4+ Al → Al2O3 + HCl+ N2 + H2O

  9. The copper atoms LOST ELECTRONS; i.e., they wereCu0 (s) → Cu2+(aq) + 2e1-

  10. The silver ions GAINED ELECTRONS; i.e., they were1e- +Ag1+(aq) → Ag0 (s)

  11. How will you remember which is OXIDATION, and which is REDUCTION?

  12. This type of reaction is ___________ a redox reaction.Single replacement Combustion Combination Decomposition reactions Double replacement

  13. We will be doing a demonstration that includes redox reactions. The demo is called the “Hindenburg.”It was the “pride” of Nazi Germany – and capable of crossing the Atlantic Ocean. (1930’s)

  14. For our demonstration, we will create a model of the Hindenburg.

  15. To generate the hydrogen gas:aluminum + hydrochloric acid

  16. 1. __Mg + __Al(NO3)3→ __Mg(NO3)2 + __Al

  17. 2. __Li + __CaCl2→ __LiCl + __Ca

  18. 3. __K + __H3PO4 → __K3PO4 + __H2
