So, can you find the answer for stating Observation atau pemerhatian khas untuk Paper 3?
Lets discuss it here;
For Set I:
Observation 1 : Before the reaction the colour of solution is blue, but after the reaction the colour of solution is colourless
ANSWER : Blue solution turns to colourless.
Observation 2 : Initial temperature is 28 degrees C, but the highest temperature is 36 degrees C.
ANSWER : Temperature increases through out the experiment // The reaction is exothermic reaction.
For Set II:
Observation 3 : Before the reaction there are solid Ammonium chloride, but after the reaction Ammonium chloride solution is formed.
ANSWER : Solid dissolve to form colourless solution
Observation 4 : Initial temperature is 29 degrees C, but the lowest temperature is 25 degrees C.
ANSWER : Temperature decreases through out the experiment // The reaction is endothermic reaction.
So, now everybody can get 3 full marks for stating observation in Paper 3 Chemistry.
Good Luck!
