emath paper was really screwed today. O:
i practically threw away 45 marks.
thats like more than half the paper can.
even the first question was so demoralizing.
its like, seemed really easy when you read it and when you actually try it out, you find out you cant solve it.
what the pink.
spent the whole half on hour doodling on my paper.
and drawing the entire hall on the last pg.
gonna heck the whole paper.
if Os is gonna be like this, omg.
i so dont know what i'll do okay.
chem paper in the morning wasnt so bad.
considering that i didnt study much for it, i though i did quite okay.
except the electrolysis part -_-
i forgot where's the cathode and anode. wtp right.
and the first question that came out was MOLE CONCEPT!!
wtppppppppppppink. half of the class (including me, lol) didnt know how to do it.
the question was like,
whats the concentration of CaCO3.3NaSO4.Mg(OH)2 somethingsomething
with respect to SO4 2-? !!! right. -_-
and i made a really freaking careless mistake! O_O
1(a) calculate the no. of moles of zinc used.answer: 0.02 mol (i got the answer)
(b) calculate the no. of moles of sulphuric acid used.answer: 40 mol (i got the answer)
(c) write the chemical equation with state symbols.answer:
0.02 Zn + 40 H2So4 -> ZnSo4 + H2
(and then i tried to get rid of the 0.02 by balancing the equation.)
(final answer) 40 Zn + 40 H2So4 -> 40 ZnSo4 + 40 H2
!!!!!! i shouldnt even put the extra 40 infront at all!
it was already balanced!
gahhhhhhhhhhhh stupid mistake!
other than that, it was relatively easy.
oh and hahahaha.
may tan came up to where i sitting before chem paper.
so funny can.
ms tan: -pinches my arm- you dare to ask me if the question was comparison or evaluting!
me: ow ow oww! i wrote evaluating!
ms tan: -walk away- then you die lor (and then she gives the evil smile)
me: but alot of other people also wrote evaluating!
ms tan: then you all die lor!
-____________- whatever can. HAHA.
ms tan is so funnnyyyyyyy.
sigh. gotta go.

i think i'll totally screw amath, but bio im confident. HAHAAHA :D
see you around.
