Okay lets wait for Ari's diagram then >_<

oki doki

[elemis]

Its should be this :

Its should be this :

but u dont hav ot extend the  C6H4 and the C2H4 :/ but its up to u

[blackberry]

WRONG
concentraion affects the amount of product ! but yeh less reactant will give u less product :/ ur sayin opposite to wht u said

umm...actually concentration affects the time it takes to form the product provided evrythin else remains the same!
so amount of product formed always remains the same!!!! (textbuk is in my face, and buks dont lie!)

oh...umm...By the way i got it!!!!!thanks!!!!!

So my diagram was correct after all .......?
ugh you scared me .. and my question was.. do you see the C double bond O at the begining .. ? This makes it -OC but the MS wrote -OOC.. but my diagram is correct so screw the MS

LOL !!!

 True what you say about extending the chain, but then again..... why take the risk ?

Whats the hardest exam between 1993-2002?
Ill solve one of them then im done >_>

it depends , if u use a higher concntaion with same amoutn of zinc , thn the product is same

but if zinc was in excess if u increase concentratin u increase product

Can someone please draw the structure of the alloy BRASS 

[mdwael]

metal+water=metal hydroxide the hydrogen? in summer 2003 p3 it says its metal hydroxide and hydrogen but why not metal oxide?theyre talking about metals caesium barium and lanathium

Any metal Above Ca reacts to give a hydroxide and H2.. im talking about the order in reactivity series..

[Raywin]

All the same......

THANKSS..

Yes when having a balanced equation it's a ratio..

Get it, i can post an example

what the hell r u talking abt??

^^Basically for ALL alloys(depending upon number of metals), By the way you don;t have to know the structures.

Guys, a silly doubt Whats the difference between Heat, Roast and burn in air.. Thanks.

Roasting in air (just means heating very strongly in air).

Heating is not as strong as roasting (by miles).
