The entire paper was easy
for physic the g value of gravitational acceleration is ~9.8
confirm chop correct cuz when u make inference with physical theory,free fall is 10m/s^2
for experiment,there are minor human error
so 9.8m/s^2 is definelty correct

jia lat jia lat liao lah!

thank Godddddddddddd! this is the first time ever i attempted calculating gradient...Originally posted by 0lala:The entire paper was easy

dun u do it in maths?
Y difference/X difference -
I didn't get the answer correct for both PHY and CHEMOriginally posted by 0lala:y?
For chem,more marks are given for observation rite? -
i dun think so,
for observational skills,the marks are usually 1 per question. -
All the best

For the last chem question,how did u answer?Originally posted by Madeleine:thank Godddddddddddd! this is the first time ever i attempted calculating gradient...
for me,
brieftly-
add suphuric acid to the zinc oxide until in excess,then pour them over a filter funnel with filter paper.colelct the filtrate in a beak and heat them until there is a hot and saturated solution.leave it to cool for the formation of crystal and thereafter dry them inbetween sheets of filter paper.

i rbm abt 10 marks for observationOriginally posted by 0lala:i dun think so,

Nt very sure though -
total marks is arnd 10Originally posted by xiaosotong:i rbm abt 10 marks for observation
Nt very sure though
but they are segmented in to i),ii),iii)
and each is 1 marks -
the practical that you all are talking about is combined science isit?

yesOriginally posted by jaydunkfull:the practical that you all are talking about is combined science isit? -
orh... when i first read it i thought i missed my practical or sth gave me a scareOriginally posted by 0lala:yes

I thought Zinc Sulphate is in the mixture of Zinc Sulphate and water. So I wrote down the crystalization process before drying it with filter paper.Originally posted by 0lala:For the last chem question,how did u answer?

u?
I've add in an equation.
ZnO(s) + H2SO4(aq) ---> ZnSO4(aq) + H2O(l)
[Neutralization process.] -
When I do the Flame Test. .Wahhh the colour Soooo NIce, So i try it afew more times. ^^,
-
I wonder why they give filter paper and other useless stuff like measuring cyclinder, filter funnel, etc.. for the chem. Lame lor..
And for the bio, walau, the 3 marks question jialat. I wrote use potometer... -
What was the flame test for ah? I just wrote a green flame was observed.Originally posted by Darkness_hacker99:When I do the Flame Test. .Wahhh the colour Soooo NIce, So i try it afew more times. ^^,

correct

Correct. Nice hor the colour.Originally posted by dahliamorie:What was the flame test for ah? I just wrote a green flame was observed. -
nabei they didnt give magnesium
could have stole em -
I dunno what will happened if one year's question come out on potassium.
