i ask you one last one
give me the formula of copper oxide

CO thing thing de !!

are you sure?
.ddrew™ __ give me your loneliness, and I'll give you my tenderness. says:
O is oxygen ma
copper + oxygen ... EHH WAIT
I MIXED UP
Cu cai shi copper >_<
CuO !!

correct

*phew*
=); ゆきと. Back to the past. (1991, 1993, 2000, 2002, 2003, 2005) says:
copper (II) oxide
nono
copper oxide right
you forgot something
if they didn't mention (II)
you must take it that copper is +1
oxygen is 2-
become Cu2O
you forgot '2'
.ddrew™ __ give me your loneliness, and I'll give you my tenderness. says:
eee .. then wad's the diff between the (II) and no (II) ?
=); ゆきと. Back to the past. (1991, 1993, 2000, 2002, 2003, 2005) says:
okays i explain in very detail
let's say copper oxide only
you must assume that copper is only +1
oxygen as usual 2-
than combine Cu2O
but if it is copper (II) oxide
Cu 2+ for copper this time round
oxygen O 2- as usual
combine together than CuO

orh ~ liao gai liao gai . wait i re-read again
=); ゆきと. Back to the past. (1991, 1993, 2000, 2002, 2003, 2005) says:
another example
Iron (II) oxide and Iron (III) oxide
for Iron (II) oxide,
as Iron in here is Fe 2+ than Oxygen as usual 2-
combine become FeO
for Iron (III) oxide,
as iron in here is Fe 3+ than oxygen as usal 2-
combine become Fe2O3
Fe and Cu are example of transition metals and they have various charges for some
and you need to look at the name carefully before writting down
.ddrew™ __ give me your loneliness, and I'll give you my tenderness. says:
especially the (II) part ?
=); ゆきと. Back to the past. (1991, 1993, 2000, 2002, 2003, 2005) says:
yes.
that is damn impt
whether can you balance eqn
is up to that
and also if let's say you forgot what is the formula of potassium sulphate
you can write K+ first than SO4 2-
then criss cross the + and - like maths that kind
the 2 bring down to K and 1 bring down to SO4
become K2SO4, ( for 1 you don have to write it down)
it works for almost all ionic compounds
which are metals and non metal join together
not suitable for organic compound like methane, ethene etc
or covalent compound like carbon dioxide, nitrogen oxide
covalent compounds-> non metal react with non-metal
that's all

woh .. very .. i need time to understand all those . >_<
=); ゆきと. Back to the past. (1991, 1993, 2000, 2002, 2003, 2005) says:
you can copy down first
tmr slowly analyse
.ddrew™ __ give me your loneliness, and I'll give you my tenderness. says:
i think i will post it all up onto my blog . easier for me to read >_<

i choose to be unnamed

who wants to put your name down anyway? =X xD

good zzz
rmb that criss cross method ONLY WORKS FOR METAL AND NON METAL COMPOUND
NOT FOR NON METAL AND NON METAL COMPOUND, IT NEVER WORKS FOR SUCH COMPOUND
sorry someone. i lazy to edit it tonight.
maybe tmr . >_<
good night !
