Dr B, is wrong
People, I don't know if I'm in the right way... Could someone HELP too??
w = what we want to know h = 6.63 x 10^-34 J s m = 9.1 x 10^-31 kg (mass of an electron?) v = I think that I calculete not im m/s
now, we use the de Broglie equation to find the wavelength. Broglie equation: w = h / m v, where w = wavelength; h = Planck's constant in J/s; m = mass in kg; v = speed in m/s.
the velocity of the electron is sqrt(2E/m) where E is the bond energy for NN and m is the mass of electron. So, v = sqrt (2 x 36.49 / 0.000548597 amu) v = 72.98/0.000548597 v= 133030.25
as bonjo said, let's try to do together - rearrange the equation to make BE(N-N) the subject. BE(NCl) - 96.3[X(N)-X(Cl)]^2 = sqrt[BE(N-N) x BE (Cl-Cl)] BE(NCl) - 96.3[X(N)-X(Cl)]^2 = sqrt[BE(N-N) x BE (Cl-Cl)] (BE(NCl) - 96.3[X(N)-X(Cl)]^2) / sqrt [BE

I put the answer of ongrwa and it's WRONG
manfred, your answer is WRONG
According to Miller Index we express the vector as a set of whole numbers, so I multiply through by 3. So, I've tried the crystallographic direction of the red vector as(10-3), but it's still wrong...
apply synonym write a different sentence.use a synonym we had a nice time at the picnic.
Thanks a lot I figured it out yesterday by byself.. Thanks a bunch anyways
