Hmm... According to my TEACHER. ( My uncle actually... so i can really trust him =D )
Weak acid has PH of 3-6. So.... =D

Give me some examples. I'll try and enlighten you if i can.
If the question asks Concentrated Ethanoic Acid. IMHO, its still a weak acid. Because ethanoic acid IS A WEAK ACID.


For example,
A weak man.
A weak man is STILL A MAN. Even though he is weak. ( Lol out of topic)

Sejarah is d worst-hellofa subject that d Malaysian Education Minister shd NEVA put in SPM. Seriously, you're not the only one facing this problem bro.
My advice is, Go to a library. Or, throw away your comp, phone, tele, PS, balblabla...
Go to library. Tell ur mum to lock ur comp. etc etc....
Im sure you will have no choice but to FOREC URSELF to study. DOn't worry, you'll do fine =D

Form 5 add maths hmmm.....
None are hard. But i'd guess MORE student would have difficulties in

1) Integration ( the volume part)
2) Trigonometry
3) Probability Distribution


Cmon la vick... score 89 in Chem u think Add maths is hard for you ? You kidding ?

Vick.... i have a task for you. Re-read all your form 4 chapters. Everything you don't understand. Just assume its from Form 5, and you have a long way to go. And, go read ALL THE STORY BOOKS from d store. U sure can pass ur time one. =D

Okay..... go to the nearest bookstore. =D

Care to explain ?

Proof ?

how'd u even do question
i) ?

can't even get the x^2 + y^2

I thought we find the vale of "x" from this equation ? 2x^2 - 3x + 4 = 0
Then from there, we get the value of X ( 2 values since its ^2 ) to sub as X and Y.
But cannot solve the equation.

Sry, i don't know your method

Okay i got it. thanks

SWT.... I ALSO STIL DOTA MARH...
