wud this hav 2 do sumthin with the reactivity series???

but obv

[jellybeans]

but obv

eh? so whats the rule for this? 

[username]

but obv

yh
because i mean
im lost in that subject...

[nid404]

Read through your textbook.

There's no rule as such. it's just based on reactivity. Some metals are simply more reactive than others.

no not that way
it ws sumthin like
above 'this' metle
only elctrolysis
and so on so forth

cud u tell me bout that
like explain
plz?

and for my question, i couldnt find it in my textbook. which is why i had to ask on sf? lol

[rameeziiii]

whats your question? and could someone please explain how increasing pressure,temperature, and other stuff affects reactions in gases

[$H00t!N& $t@r]

sorry i have another question...
 s09 q9c  
If it has already been answered then can u please give me the link

its okay hehs got the answer already..

anyways.. your question.

increasing the pressure will shift the equilibrium to the side with less molecules
so for example A+B <-> C , increasing the pressure here will shift the equilibrium to the right & youll get a higher yield
decreasing the pressure will shift equilibrium to the side with more molecules
*only applies to gases

increasing the temperature will favour the forward reaction in an endothermic reaction
decreasing the temperature will favour the forward reaction in an exothermic reaction

increasing the concentration on the reactants side will shift equilibrium to the right & hence increasing yield
increased concentration on the products side will shift equilibrium to the left & hence the rate of backward reaction will be greater than the forward reaction.

hope it helps? :b lol.

Can anyone answer this?
"Draw a labelled diagram to show how could u condense and collect the water vapour produced when a hydrated salt is heated".

umm... i already know this ,see i was kinda wondering why this happens... sorry

hope this is wht u need

[blackberry]

radioactivity is not in our portion right?? (cant be bothered checkin the syllabus)
its ther in the previous papers but not in ny of the recent papers!!

[rameeziiii]

hope this is wht u need

or maybe this.... idk if its correct
