    Problem about lattice structure proof

    I have done "small bit" of studying on this concept, I have not yet come across a mathematical answer that shows this "interval". It can only be understood physically, but expressed mathematically. I'm not saying that it's not possible (I can have an "interesting" math imagination), but I have...

    Calculating Bandgaps Experimentally

    I've been doing a bit of reading on bandgaps of semiconductors and alloys of semiconductors. I was curious to know is the bandgap of a material, say Silicon, determined or calculated experimentally? How do scientists usually determine this in the lab?

    Acid/Base Comparison: Understanding Conjugate Stability and Electronegativity

    This rule is for homolous acids. When comparing phosphorous acid and phosphoric acid, again you must compare the stability of its conjugate base. The differences in determining relative stabilities is no longer comparing the electronegativities between nonoxygen atoms (not simply because the...

    Quantum Numbers: Why (3,-2,0,1/2) is Invalid

    I agree. n = 3 l = 0, 1, 2 ml = -2, -1, 0, 1, 2 ms = -1/2 or 1/2 l cannot be negative, but ml can be.

    Are these reaction mechanisms drawn correctly?

    Does this reaction have two known mechanisms? (i.e. is it given that there are two mechanisms) What is the solution (water or X-N)? And what are you "hoping" to be the final product(s)?

    Acid/Base Comparison: Understanding Conjugate Stability and Electronegativity

    Try thinking of (4) a bit differently. Chlorine is more electronegative than Bromine (Electronegativity increases up and right on PT). This implies that Cl "loves" its electrons a bit more than Br, and wants to hold on to them. Because of this, the conjugate base of chlorous acid is a bit more...
