9priyam its gud that u too ve done that , so then they must be rong na ?

11. Ans given B but then isnt stat 2 false ( lnK is prop to ΔH )
12. Ans given C but then (stat 2 is true bcos of the const solubility product and stat 1 is false )
99resolved ;)

ans given as A tell how stat 2 explains stat 1

this ones a REAL IMP Q 
ANS GIVEN A pqr B pq C qrs D pqr i wonder how speed of sound changes ? doesnt it depend only on medium and vel of medium ?
13Obs B ans must be wrong.... i think there should be s atleast
21hey cele!!
On dilution, the concentration of AgCl will decrease na....
Solubility product is a const quantity only 4 saturated soln. so the ionic product will be lesser than the Ksp in this case(i.e. on dilution)
Correct me if I'm wrong
9q resolved ;)

how many nos btw 1 AND 2000 exist such that the sum of the digits of its sqr is 21. 5 , 7 ,20 or none ? ANS /hide]none of these ;)
9tapan yes agreed but atleast stat2 is partially right na
isnt stat 1 fully wrong ?
33hey in that match the column... doppler effect.. i also wrote the same answers..
qrs

62this is done by F=d(mv)
You have to use this alone.. that will help you solve it.
13any one plz... Q23...[7]
doppler effect ans wrong....must be....
9@nish i solved usin that method and got ans as 8√5Ï which din match wit their ans ;(
pls solve it and confirm if u r also gettin my ans or their ans
also try that doppler q its very imp for me
21Cele,
for que12
Ur post reads the answer as C....
so it conforms with wat u say.... stat2 is rite, stat1 is wrong
21dude,
how is compound in question a meso one, it doesnt seem 2 hav a plane of sym coz ther is no image of C=O
1how many nos btw 1 AND 2000 exist such that the sum of the digits of its sqr is 21.
5 , 7 ,20 or none ?
ANS none of these ;)
if sum of digits = 21 ,no is divisible by 3 but not by 9,an impossibilty for a perfect square
1hey celes, for q.12 >> stat 2 is false only naa...
with dilution, conductivity ALWAYZ increases...
1and there are loads of other mistakes as well..
in chem , in hydrolysis of esters in second paper ... ans shoud be A ..
then , there was a road map ... of amines ... there they didn gv the option of +ve carbylamine test as corect ...
God knows wat they do...
this test had more mistakes than any of the previous ones...
then how to rely on the rank they will gv !!
33Yippie!! solved the one at the top of the page...
was doing 2+2=5 [3]
33koi comprehension me kuch karo naa.. chem wala (q21 22 23) post :5
nahi bana... [7][12][2]
11Q10
the ball rises to high temp showing it is a bad emitter
so good reflector and so appears dark
15.) solved this in a stupid way...
see.. only 41 is a square of two no.s ...25 + 16..
and there is very low possibilty of D ... i mean generally ...
so it was a perfect tukka...
