    Chemistry: Post your doubts here!

    relative height of 37Cl to 35Cl is 3:1 or 75% and 25% so RAM=((75x37)+(25x35))/100=35.5 once again dont thank me just get some one to anwser my question on diazotisation please

    I asked my teacher told me this- Purines with prymidines, ocuppy same space between the backbone strands,space constant more stable complementary base-pairing(ATCG,hydrogen bond)is crucial to for replication and gene expression.,DNA is semi-conservative

    thanks Amy Bloom but i want to put an argument for the case of importance of base pairing cant we say that base pairing keeps the bases inside so that it is less likely to damage from outside,and hydrogen bondind of base pairs stablilzes DNA take no offense from the argument, i just want a...

    abruzzi the anwser is X, as when cos(120)=-0.5 resolve all forces towards s3(minus mens its in oppsite direction) we get Funknoen=.5F+.5F so funknown=F identical spring so spring constant is same (k)x(Eunkown)=kX so Eunkown=X dont thank me just find someone yo anwser dvantages and...
