a] so let the hydrocarbon be 100g then mass of C is 82.6g mass of H is 17.4g then n(C)=7.. n(H)=17.4 mole ratio: C:H is 1:2.5 so empirical formula is C2H5 so no, i dont it is an alkane.. XD..but mite be wrong, wat u do think...

i dont realli think the Q is set right but hell it is maths Q Q1. a] on the same graph, graph y=|x| and xy=1 b] on the same graph, colour the region y<or=|x| and xy<1 the thing is, i found the region, but to draw both question on the same graph is stupid coz a] requested xy=1, so do i...

i don realli haf Qs but .. XD.. i cant remember anything in specific~~~ how did u test go? Oo

ok i will answer the sample of metal will increase in mass due to the mass of the oxygen in its oxided form. =P bingo

ohh so when they talk about "samples of metals" we include the oxygen too? xD?? i thot it is juz the mass of the metal... thx =P

nah the whole thing is heavier coz of oxygen...hmmm..i reckon it is gonna remain the same oh well, finger crossed, hope there is no that Q in my test. =P

like umm... potassium, sodium, magasium..etc. etc. =] i catn remember all that equations, so i will juz go with my instinct... =O=..usual wrong tho

thx for da paper. =P i need to cram badly juz did maths 2u... reckon it was easy, juz stuck on one question chem tomorrow. XD

LOLZ.. nah not realli, i juz travel around a lot. =P... and meet pplz. but neva got to know them as such ...we didn't cover the whole trig section either. =\..

diamond graphite fullerene real world application??? diamond - jewellery - sparkles when polished and cut glass cutting and polishing, mineral exploration drills, dentist's drills record player needles graphite - electrode in dry cells, dry...

err then the whole sentence is correct, i am looking at that page in "chem context 1" rite now,, juz not consuming anything inside my brain.. XD

u srs? i think our whole yearly is gonna be base on that crap it is juz the heat energy required to change the temperature of 1g of a substance by 1Kelvin ....i think i spelt the last word rite... X___X

*looks around* betta not go off the topic b4 someone yells at us.. hmm.. economics test papers.. ^O^

lolz. =P chatty is like yonks away for me.. =\ i onli go there for special occasions..xD

grrr.. studying is not my hobbie... =|.. oh well.. i will cram.. like the word "explain" the meaning of specific heat capacity .. wat u explain about?.. wat is the cause? effect? the relationship.. XD

yea i am kinky =] i bet i can trace u up in like.. a day i know people who know people in st ive who know u.. xD

=| i live in lidcombe....xD... even tho i am like an epping person.. (well half half now) gr8t.. i should realli use this holiday to travel around and go to all the colleges..xD
