Its gna be D ! Cuz half mole of oxygen is produced !

rightie..thanks

 

[a.abid]

I think u got it wrong

D hi hay tumhaara?

 

[kitecrystal]

D hoga ..

2 moles h2o2 kay aik mole bna rahay hain O2 ka .. then 1 mole half mole banaye ga ..

and the volume of product always starts from 0.

JazakAllah!

Lekin un ka molecular structure to same ha na .. :-\

OH aik group hai dada .. O aur H ko alag kardia tu OH group kahan raha!!!!!! aur hamesha iss tarah ki bond hoti hai ..

C-O-H bhalay ye O-H kahin bhi lagay .. but O C kay sath hoga aur H O Kay sath ..

D hi hay tumhaara?

lekin maydah ne to organic se sawal se pucha tha kuch isomers wala aap ne shayed wrong bandey ko reply kiahai..

 

[MustafaMotani]

D hi hay tumhaara?

leave it or confusion hogi..

tum keh rahoi to maan leta hun..

Q and R only.

P mein beech mein aaraha hai O.. and is not forming the OH as in others .. so others are alcohols while idk what this P is .. but its not an alcohol.

The answer is option D ! But i dnt get it y is this also an isomer ?

 

[a.abid]

leave it or confusion hogi..

wat if it comes? :O batao wat did u get? :O i got D

 

[kitecrystal]

which two gases are formed when copper(II) carbonate and magnesium react with each other?

 

[MustafaMotani]

wat if it comes? :O batao wat did u get? :O i got D

I meant u got on different mCQ..
the mcq she asked was about isomers

 

[Mayedah]

wat if it comes? :O batao wat did u get? :O i got D

Im talking abt the isomers question !

 

[MustafaMotani]

Im talking abt the isomers question !

do you know the answer.. ?

 

[Mayedah]

do you know the answer.. ?

Yes irs D but y ?

 

[MustafaMotani]

which two gases are formed when copper(II) carbonate and magnesium react with each other?

where did u get this question .. ?? no gas should be made..

 

[MustafaMotani]

Yes irs D but y ?

den its becoz all have same structural formula I guess

 

[daredevil]

MustafaMotani u're talking abt ur post where u told wo overcoming the change wala point ryt?? i read it and i perfectly understand that temperature part. but i don't understand the role of pressure in equilibrium. i undertnd temperature bcuz of the reaction being exo- or endo- thermic the changes take place accordingly but ye pressure kis marz ki dawa hai!! >__<

 

[Mayedah]

But O is attached to thefirst and second carbon in option P and so is the same in option q and R !

 

[daredevil]

where did u get this question .. ?? no gas should be made..

y won't a gas b made?? wud carbonate not react with Mg?

mein ne aap ko pressure wala parhne ko kaha tha w8 i ll post again

Mg should simply displace Copper
