ANSWERING ALL BIO/CHEM PAPER 1 DOUBTS :)

[igcsedude_Jor]

sorry for late reply...i was solving L.V.D's doubt

Thanksssssssss aloot!!!

Displacement wont occur…Displacement is when a metal replaces a less reactive one from its solution…In that case,there are two compounds so displacemnt doesn't occur…

in this case they are ions...not metal!
so a reaction will take place.

thanks..no prob tyt!

Thanksssssssss aloot!!!

it's okie...juss remember me in your prayers

 

[сᴏᴏʟ сяуѕтᴀʟѕ]

thanks..no prob tyt!

Your welcome

y its not possible if a more reactive metal takes place of the less reactive one?

 

[Skynox]

If A reation will take place but not displacement :/Double substitution

sorry...didn't get you!

i donno what izzit called...may be not displacement but whatever it is...a reaction will occur...i am sure that is what matters

Yeah…I am saying that displacement metal-compound of less
Reactive one …
In that case a very slow reaction will take place……

 

[svenas]

sorry...didn't get you!

I mean if reaction was like between sodium and calcium hydroxide..wat happens...?

 

[сᴏᴏʟ сяуѕтᴀʟѕ]

I mean if reaction was like between sodium and calcium hydroxide..wat happens...?

a displacement reaction will take place cuz sodium is more reactive than calcium, forming sodium hydroxide and calcium..

BUT
calcium + sodium hydroxide = no reaction

 

[сᴏᴏʟ сяуѕтᴀʟѕ]

Reactive one …

umm you mean this reaction will be slow?

aha ok thanks!

 

[сᴏᴏʟ сяуѕтᴀʟѕ]

aha ok thanks!

Your welcome ^_^

Look he was asking about reacting sodiUm chloride with calciu chloride…A reaction will occur not because sodium is more reactive than calcium …These are compounds so it is not displacement…According to your sayings if the reaction was between calcium hydroxide an sodium chloride,nothing happens ????!!!

these are ions so reactivity doesn't matters..

a reaction will occur in both the ways!

 

[Skynox]

So it is not displacement and the reaction will occur not because of reactivity…It is not called displacement again GAK!!

 

[сᴏᴏʟ сяуѕтᴀʟѕ]

yeah...i don't think it is called displacement...
GAK?

 

[svenas]

yeah...i don't think it is called displacement...
GAK?

maybe double displacement?
