Hello, How can I calculate the bond dissociation energy for K+Br- when I only know the the length of the bond? Equation D0 = De - 0.5hω does not help because I do not know ω and De. ω is the vibrational frequency of the bond. Thank you for your advice beforehand.

Thank you for answering. But I don't really understand the point. Actually this time the explanation and deduction is more useful than the actual answer.

Homework Statement The values for the charges on oil drops are 3,99 6,65 2,66 10,64 3,99 and 9,31 all these multiplied with x10-19C. What is the largest value of the fundamental unit of charge that is consistent with the measured charges? Homework Equations Fundamental unit...

I my case it is cosθm. Yep, I think this should be the right answer because the angle is bigger than 45o.

Homework Statement What is the angle of the first order diffraction, m=1, when X-rays diffract from a crystal in which a spacing between atomic planes is 0,175nm? The 2nd diffraction, m=2, occurs at 45o. Homework Equations Δr=2dcosθm=mλ m+1/m = cos45/cosθm , because when the m...
