Update of Year 2009 Spotted Topic In SPM Chemistry Paper 2

Chemistry SPM 2009 exam had finished, I wanted to update my spotted topics with the real SPM Chemistry papers. Those I bolded with colour are the topics that came out in the real SPM Chemistry Paper 2.

1. Empirical formula – study for both CuO and MgO
- Precautions when carry out the experiment
- Draw set-up of apparatus
- Observation
- Calculation in determining the empirical formula ( Question No 3 in Paper 2)

2. Periodic Table
- Group 1 element – both physical and chemical properties (Question No.2 in Paper 2)
- Group 18 element – physical properties and uses
- Transition element – special characteristics
- Amphoteric

3. Carbon compound
- Alkane
- Alkene (Question No 4 and No7 Paper 2) ( Alcohol also came out again this year)
- how to prepare ester - when an ester is given, you should be able to name the
alcohol and carboxylic acid used

4. Chemical bond
- Describe formation of ionic and covalent bond
- Conductivity of electric and heat
- Solubility in water and organic solvent

5. Redox reaction (Experiment about reduction and redox reaction by the transfer of electrons at a distance) (Question No 9 Paper 2)
- Explain the process of rusting
- Define term of Redox reaction

6. Electrolysis
- Chemical cell (Question No 8 Paper 2) (Factor of concentration for electrolytic cell also came out this year)
- Define term of chemical cell

7. Soap and detergent
- How to make soap
- Advantages and disadvantages of soap and detergent
- Process of cleansing action

8. Contact process and Haber process
- uses of sulphuric aced
- uses of ammonia
- industrial process of ammonia

9. Thermochemistry ( Heat of neutralisation, I didn’t spot this heat because it has came out before. It seems like next time we should cover all the heat. Heat that had come out will come out again and heat that haven’t come out not necessarily will come out in the following year)
(Question No 6 Paper 2)
- Heat of displacement/ precipitation – same concept in calculation
- Heat of combustion

10. Salt
- Prepare soluble salt or insoluble salt – learn to draw apparatus set up
- Indentify anion or cation in a given solution (Question No 10 Paper 2) (Question about acidity came out again this year in this same question)

11. Rate of reaction ( The factor of concentration, I didn’t spot this factor because it has came out before. It seems like next time we should cover all the factors. Factor that had come out will come out again and factors that haven’t come out not necessarily will come out in the following year) ( Question No 5 Paper 2)
- Factor of catalyst
- Factor of temperature

12. Manufactured substances in industry
- Uses of alloy, glass and polymers
(Question No.1 in Paper 2)

13. Experiment of vulcanized and unvulcanized rubber
