With an aqueous solution containing Cu(I) ions complexed by ammonia, isomer P gave a red precipitate. On vigorous oxidation by aqueous manganate (VII) ions, isomer Q gave only ethanoic acid whereas isomer R gave an unbranched chain, dicarboxylic acid. Write structual formulae for isomers P, Q...

Thank you v. much. I'm going to read my physics book about what you said to learn more about them.

Sorry I meant this : What I think is that changing the energy of the electrons is the same as changing the velocity of the electrons. If you know the velocity then you know the wavelength of the electrons, due to de Broglie's equation (lambda=h/mv). And if you know the wavelength and the...

Q: Electron diffraction can be used to investigate both the arrangement of atoms and the dimensions of nuclei. Explain how changing the energy of the electrons can be used to achieve this. I need help again, but this time, not alpha-scattering experiment but electron diffraction. What I...

Thanks for good explanation. :smile:

Hi, thanks but may I ask why for b)?

I'm stuck with these questions. Please help if you can. In Rutherford's experiment, alpha-particles were directed at a thin gold foil. A small fraction of the alpha-particles were back-scattered. Explain how this result would be affected if each of the following changes was (separately)...
