damn.
what a day.
chem pract sucks la.
titration i don't know did it how many times man.
six times?!
cuz the thing keep turning colourless.
then have to do it again.
the wonderful thing is i put P into the burette when Q is supposed to be inside the burette,
then how? take out and wash again la.
wasted time there man.
then QA.
first, i don't know where silver nitrate is.
then guess where i found it?
next to the sink. right in front of my beautiful eyes.
then my mind went completely blank for calculation.
when i finally remembered how to do it, there's only TEN minutes left.
so i did. i rushed.
i for Ar of 23.5 ( cuz of my titration reading, went abit off.)
i
stupidly went to round it up.
so i put magnesium.
the answer is sodium (Ar: 23)
then when i hand up the paper
then i remembered: element M is supposed to be in grp 1 not grp two!!!
damn should have looked at the formula first.
anyways, i gotta do well for my theory man.
anyone who got other school papers,
i need more school papers!
lols. good luck.
