Re: Quiz 2 Prep. Question 6 [ENDORSED]
So the question is asking me the resonance for (NH2)COCH3 I've managed to find one structure for it. But I can't seem to find the other, unless I change the formal charge of the compound. Is that what I'm supposed to do? How did you find the structure? I've been trying to do it for the past twenty ...

Atomic Spectra Post-Module, Question 17 [ENDORSED]
The meter was defined in 1963 as 1,650,763.73 wavelengths of radiation emitted by krypton-86 (it has since been redefined). What is the wavelength of this krypton-86 radiation? To what region of the electromagnetic spectrum does this wavelength correspond (i.e. infrared, ultraviolet, x-ray, etc.)? ...
