Yes…even soalan definion is one mark je..satu markah pun markah juga!! Fahamkan then baru hafal, Inysaallah boleh😼

Hi guys!!!
baru habis exam ke tuuuu
result chemist dah dapat ke? 😱😱
spill sikit guys and bagi review exam chemist macam mana 😼😼

Halo guyss!! Ini tips untuk mengenal pasti Inorganic & Organic compounds :
- Untuk Inorganic compound, kita tengok sama ada dia:
Takde Carbon
Oxide of Carbon (cth: CO2, CO),
Carbonate compound (cth: Calcium Carbonate),
Cyanide compound (cth: Hydrogen Cyanide)
Compound yang berakhir dengan “element-ide” (cth: Calcium Carbide)(bukan cth: acetamide, formamide)
- Untuk Organic compound:
Mesti ad Carbon,
Originate from living things (cth: Protein, Sugar),
Homologous series, berakhir dengan “-ane, -ene, -yne, -ol, -oic, -oate” (cth: Propane, Methyl etanoate)

Tips!
wajib - BUAT OHEN YG SECOND LEVEL
option one
1) try untuk kenal dulu chapter/subtopic/diagram/kata kunci soalan
2) in this case, diagram tunjukkan abt the conversion of fe2+ to fe3+
3) in order to become Fe3+, iron must increase in oxidation number
4) according to ohen, increasing in oxidation number means undergo oxidation
5) Also according to ohen second level, negative terminal undergo oxidation
6)so in negative terminal..reaction occur is Fe2+ to Fe3+
the colour changes is green to brown
Option 2
3) ataupun..kita boleh je igt the oxidising agent yg empat tuu ( bromine water, chlorine water , acidified potassium manganate solution (VII) , acidified dichromate (VI) solution
4) dalam gambar pakai acidified potassium manganate (VII) solution so automatic la dia oxidising agent
5) INGATT oxidsing agent undergo reduction while reducing agent undergo oxidation
6) if satu side dah reduction, so reaction Fe2+ to Fe3+ lah undergo oxidation
7) kalau soalan tnya negative terminal…Negative terminal always undergo oxidation in VOLTAIC CELL JE TAUU!! (according to ohen second level)
8) so reaction in negative terminal is Fe2+ to Fe3+
9) colour changes is from green to brown
