Post  Guest001 on Tue Apr 28, 2009 1:14 pm

1) the # given (pos)
2) havent figure that out..
3) mu*B*cos(degrees given)=ans (pos)
4) the # given (neg)



Can someone pls post how to solve Question #2

number 2

Post  :) on Tue Apr 28, 2009 1:21 pm

for number 2

negative

e^-(given a * given x)

then square that

Smile

For Question 3 though, i keep trying

-(magnetic moment * magnetic field * cos(given angle))

and i still am not getting the answer =/

number 3

Post  :) on Tue Apr 28, 2009 1:26 pm

okies sorry for so many posts..

but i see now, you have to set your calculator to radians and after that equation, divide by (1.6x10^-19)

and ALSO my answer was negative.

cheers Smile

Question number THree aid

Post  Big Boy on Tue Apr 28, 2009 4:33 pm

You should not put your calculator in radians. Leave it in DEG.

Do:
(magnetic moment * magnetic field * cos(given angle))

Then divide what you get by 1.6E-19

Firstly, I get money. Secondly, question four requires that you haven't wasted all of your brain cells away since freshman gen chem.

Principle quantum number = n = 1,2,3,4...

Azimuthal Quant. # = l = 0,1,2,... n-1

Therefore for principle quantum number 3, l = 0,1,2 and there are therefore three predicted subshell or orbital shapes, the s, p and d shells.

#3 -- got it!!

Post  PHy on Tue Apr 28, 2009 11:57 pm

so for # 3 the above formula is correct, but most of you who are not getting it is probably because you are not seeing the * 10^-24 in for the magnetic moment number.. its easy to miss since its in the left corner of the second line...
and no need to change to radians..even if you get a negative number, the answer is pos.

#3

Post  gamblerz on Wed Apr 29, 2009 1:16 pm

if ur questions stated the angle in degrees set calculator to degrees, if radians then set to radians and then follow the other guys directions for #3

Post  gamblerz on Wed Apr 29, 2009 1:27 pm

and for #4 so take the negative of the number n...one significant digit is enough

Question 2

Post  an0n on Wed Apr 29, 2009 3:36 pm

this is what i understand from it (please correct me if I'm wrong!)

based on Slide 14: probability to observe particle at location x = (psi(x))^2

psi(x) = e^-(a*x)

ratio:

psi(x) = (e^-(a given * x given))^2 / (e^-(a given * 0))^2

e^-(a given * 0) = 1. Therefore, the ratio is just (e^-(a given * x given))^2

hope that helps

Question 2 continued

Post  an0n on Wed Apr 29, 2009 3:54 pm


ratio:

psi(x) = (e^-(a given * x given))^2 / (e^-(a given * 0))^2

ignore the crossed out part


remember, answer is negative, as posted earlier by someone else
