LianKeXuan SG =) jia you all...and i hope u can get into the schools u want =) continue to strive harder !!! jia you !!!!
0lala SG 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 ^^
xiaosotong SG I didn't get the answer correct for both PHY and CHEM For chem,more marks are given for observation rite?
0lala SG For the last chem question,how did u answer? 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. u?
Darkness_hacker99 SG 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. I've add in an equation. ZnO(s) + H2SO4(aq) ---> ZnSO4(aq) + H2O(l) [Neutralization process.]
Darkness_hacker99 SG When I do the Flame Test. .Wahhh the colour Soooo NIce, So i try it afew more times. ^^,
Darkness_hacker99 SG 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...
