of course thapar

kindly give the detailed solution.i'm not getting the answer yaar plzzzz

according to me its just a convention,there is no logic reason behind it

find the area of the reigon enclosed by the parabola x²=y and the line y=x+2

answer:50/3 sq. units

it is a reaction shown by aldehydes having alpha hydrogen.

find the area included b/w the parabolas  y²=4ax and x²=4by?

answer:(16/3)ab sq. units

thnxs guys

thnxs a lot

yaar even i'm also not understanding the p statement

1.integral of tanxdx=log [secx]

2.integral of secxdx=log[secx+tanx]

3.integral of cosecxdx=log[cosecx-cotx]

when delta g is negative,it means that the reaction is spontaneous i.e it takes place by itself without the help of an external agent e.g. a hot cup of tea when kept at room temp. becomes relatively cooler after some time.this reaction is spontaneous.so,according to me no work is done by the surroundings!!!!!!!! 

i was having the same problem but after i bought op aggarwal's organic chemistry by disha publication,all my problems have disappeared in thin air.believe me.its a gr8 book having mcqs,exercise questions,topic wise questions and comprehension questions.its just a gr8 book!!!!!!!!!!

go and buy it!!!!!!

A.simple cubic and face-centred cubic parameters

B.cubic and rhombohedral

C.cubic and tetragonal

D.hexagonal and monoclinic

P.have these cell

Q.are two cell systems

R.have only two crystallo-graphic angles of 90⁰

S.belong to same crystal system

answer:

A-P,S

B-P,Q

C-Q

D-Q,R

plz explain me all the answers
