what an ultra bad day.. =(
the practical sucks.
FOR THOSE PEOPLE TAKING SUB SCIENCE:
the salt X is NOT ammonium nitrate. it is SODIUM nitrate.
AHHHHH! almost everyone put ammonium nitrate. INCLUDING ME!
and in order not to conflict with my answers, i put the moist red litmus turns blue when it is suppose to be no visible reaction.
im the dumbest asshole in the world.
the metal oxideY is copper(II) oxide. for those people who put a different answer, you ought to be shot.
or prepare to retain this year. the answer is sooo damn obvious.how can anybody get that wrong.
the physics prac sucked just as much too.
its a lens experiment. i had difficulty comprehensing the question.
it wrote, "find the height of the image."
IT SHOULDN'T BE HEIGHT FOR GOODNESS SAKE.
its width!!! [stupid lee phek guat. she should brush up more on her english]
i was thinking whether to measure from the base to the image or only the size of the image.
and i looked around me for information.
the first person i turned to was eunice. she measured from the base to the image.
i turned everywhere. and almost everyone was measuring from the base to the image.
majority wins. hahaa. and dickson too, measured from the base.
EVERYONE IS WRONG!
lalala~ fail.
i even got the focal length wrong.
tsk tsk.
i think i should have spent the time cleaning my test tubes.
since i flunk the whole shit thing.
okay.
sorry diane, for the fifth time i guess.
