**Organic chemistry: dehydrohalogenation**

P.S. I understand the mechanisms of E1, E2, and dehydrohalogenation. I just don't know how to find out whether an alkyl halide undergoing dehydrohalogenation will follow an E1 or an E2 reaction.

**Organic chemistry: dehydrohalogenation**

Hello. I know you guys don't do organic chemistry but because I got so much help from you guys in general chemistry, I was wondering if you guys can help me out again. :P Here's my question. In dehydrohalogenation, how do you know whether a reaction is E1 or E2? My tex...

I have 20 puzzle tables (1,2,3,…,20) that contain of 10 rows (1,2,3,…,10) each. There are numbers 1,2,3,4,… in each of every tables, which has a unique position to every rows. I am just wondering if you can help me how to find the relations between them, so the ...

**Calculus**

OK trying again. For what (numerical) of the constant "c" is the function f(x)= {x^2-cx if x is greater than -1 {cx^3+x if x is less than or equal to -1 continuous on (- infinity, +infinity)?(Justify answer!)

**Calculus**

For some reason the answer to this question is alluding me, Im sure its probbly something simple im just over looking. For what (numerical) value of the constant "c" is the function continous on (-?,?)?( Justify Answer) f(x)= x^2-cx if x>-1 cx^2+x if x?-1

**General chemistry ligand**

Hello. I have a question about ligands. How do you figure out how many ligands a central metal cation can have? For example, Cu^2+ and NH3. When they combine, it forms Cu(NH3)4^2+ Why does it form 4 ligands oppose to 6? A general rule, which isn't always followed, is to do...

Please.... I need your help! I posted this question yesterday and no one has answered it yet. Can anyone help me please? My question was: The Taylor series about x=5 for a certain function f converges to f(x) for all x in the interval of convergence. The nth derivative of f at...

**calculus-- need help desperately!**

The Taylor series about x=5 for a certain function f converges to f(x) for all x in the interval of convergence. The nth derivative of f at x=5 is given by f^(n) (5)= (-1)^n(n!)/((2^n)(n+2)), and f(5)=1/2. Write third degree Taylor polynomial for f about x=5. Then find the rad...

**Math help!**

I dont understand this. Solve -5x - 6 = -6x^2 Rearrange to 6x^2-5x-6=0 (3x + 2)(2x - 3)= 0 Set each factor equal to zero and solve for x. I hope this helps.

**Math help 2**

And this one is troubling me. 3x^0 - 2(x - 3^0) - |-11 - 2| = 4x(2-5^0) - 7x please help. Thanks I don't know if you are aware of this, but anything to the "zero power" = 1 and the vertical lines indicate absolute value (regardless of sign). So this translates to...

**Math Help**

How is this problem done? it's not coming out right for me. solve for c: x = p(1/a + m/c) cax=pc+ ma c(ax-p)=ma then divide by ax-p check my thinking.
