Chemistry SPM 2010!!!

Finally the Chemistry SPM 2010 is finish!!! A lot of hot topic never come out in this year. Such as: Rusting of iron, Potential difference, Heat of Combustion, Ionic and Covalent, Soap and Detergent, Haber and Contact.
But very lucky, the real question is easy and moderate only, not too difficult. So, everyone sure can get a good result!!!

1. Stydy the reactivity of G17.
2. Study the experiment of G17 with Ferum.
3. Electronegativity mean how easy the element recieve electron and become anion (with ' - ' charge)

Structure: Construct ECS based on potential difference

 

- Zn is higher position in ECS.
- Zn is more electro positive.
- Zn is easier to release the electron become cation.
- Electron will move from negative (-)terminal to POSITIVE (+) terminal
- The distance between two metals in ECS incerease, the potential difference increase.

Paper 3: Rusting of Iron!!!

 

1. Problem statement: How does the types of metals will affect the rusting of iron?
2. Hypothesis: The more electropositive metal will prevent the rusting of iron, while the less electropositive metal will rusting the iron.
3. Memorise the material (types of metals and solution) and apparatus (test tube, test tube holder).
4. The step of experiment: Clean --> Coil --> Pour --> Few days --> Record observation.

Paper 3: Rate of Reaction - Catalyst - SUPER HOT TOPIC!

- Remember, the manganese (IV) oxide is catalyst!
- use GLOWING wooden splinter
- do the experiment separately
- measure the material before the experiment
- must state unit / volume / mass / concentration

Chem SPM 2010: Rusting of Iron

 

- Metal place HIGHER in ECS is more electropostive
- When the more electropositive metal in contact with iron 

  nail (Ferum, Fe), the metal will PREVENT the rusting of 

  iron.
- Examples: K, Na, Ca, Mg, Al, Zn, .....

* Metal placer LOWER in ECS is less electropositive
* When the less electropositive metal in contact with iron nail 

  (Ferum, Fe), the metal will cause the RUSTING of iron.
* Examples: Cu, Ag, Au
