Hi ^^ hindi ko man naperfect ito pero parang may mali na answer.. diba po ung derivation ng combined gas law ay P1V1T2=P2V2T1 ? tapos ang pagkuha ng final volume ay V2=P1V1T2/P2T1. ung naging equation po kasi ng combined gas law dito ay P1V1T1 imbes na T2 kaya wala ung tamang sagot sa choices correct me if I’m wrong.
padouble-check nalang ^.^
medyo madali nman…sna gan2 rn ang mga tanung
If only, he he
Hindi naman masyadong mahirap. nagiging mahirap lang ang exam kapag walakang alam, ang technique lang sa pag Exam, sa bi ng teacher ko 99% pray to god, 1% Study
ang hirap naman ..!sana makasagot ako sa exam pag ganto kahirap yung given hhharrr XD
Hi!
Madadalian ka lang nyan sa exam kasi dun lang naman sa itinuro sa school sila kumukuha ng question ideas. Time pressure lang naman ang problema – at syempre, may luck factor din kasi di mo talaga alam kung alin sa mga pinag-aralan mo (o hindi nabalikan) ang lalabas sa exam.
ang hirap ng chemistry…..nosebleed!
nkaka-challenge..
extremely difficult! it needs to be reviewed before answering.
this quiz is really good… I love it…
Thank you upcat review, kung nalaman ko lang ng mas maaga edi mas maganda sana but it’s okay i’ve learned a lot.
Hmmmm… these questions are supposed to be easy but I’ve also forgotten them already.
parang mali yung Q9…shouldn’t answer be “atomic number is equal to the number of protons”
the questions given here is not hard as i expect. actually its suppose to be perfect . ahahaha !!! nakalimutan ko lang .
Thanks a lot.. sana ma help ako sa exam bukas.
whoa… NOSEBLEED! we had these lessons only last year but i forgot them already!! peace Ma’am.. O.o but Chemistry is still the BEST! ha ha ha.
