    Chemistry Find the molecules by interpreting the H NMR spectroscopy

    Each spike counts as 3 Hydrogens...so a CH3 and then 4 CH3?

    Organic chemistry determing nucleophile strength

    To determine base strength you need to look at the pKa value for the molecules conjugate acid (add an H+ to the molecule). If the conjugate acid has a low pKa (strong acid) then the original molecule is a weak base...and high pKa=strong base.

    Chemistry Find the molecules by interpreting the H NMR spectroscopy

    Well I know (atleast I think) the integrations; 1st graph: 2:3:2:2:3; One degree of unsaturation 2nd graph: 1:3:2:3:3; One degree of unsaturation 3rd graph: 1:3; One degree of unsaturation But then I can't put everything together. I spend atleast an hour one each of these but can't figure...

    What are the systematic names of ATP?

    Besides the IUPAC name and ATP I don't think it has another common name.

    Implicit Differentiation w/ trig functions check

    y*2xcos(x2) dx/dx + sin(x2)*1 dy/dx = 0 2xy cos(x2)*dy/dx = -sin(x2) What I notice is that you separated sin(x^2)dy/dx by subtraction..which is obviously "illegal" Try isolating the term with dy/dx in it and then try to isolate just the dy/dx

    What are the systematic names of ATP?

    Those are not IUPAC NameS, that whole thing is the name.

    Convergence of Series & Sequences: Tests Explained

    Well can you list the various tests that I can try to apply I understand the a_{}n+1/a_{}n test where if the ratio is > 1 and it is bounded about then the sequence converges and < 1 and bounded below then it converges. But I don't understand the reasoning behind the other ones. Those...

    Convergence of Series & Sequences: Tests Explained

    Can somebody please explain to me: How both series and sequences converge, and the various tests to find out. I've tried searching but it seems impossible to get any explanations as to why you do the specific test.
