That’s a dumb question, because It depends on the experiment. I would guess “a” or “d” because in most cases running out of time during a lab, or getting impatient, etc can give you a lower yield.
Unless I’m misreading “d”, it just seems like a more in-depth version of “a”. So it wouldn’t hurt to try that one.
Answer:
The reaction forming aluminum bromide is Al + 3Br2 → 2AlBr3
Answer:
When there are too many protons, some of the outer protons are loosely bound and more free to react with the electron. But most atoms do not have too many protons, so there is nothing for the electron to interact with. As a result, each electron in a stable atom remains in its spread-out wavefunction shape.
In an atom, there is a nucleus made up of neutral charged, neutrons, and positively charged protons. The reason why electrons which are negatively charged, don't fly off is due to its stronger attraction to the protons. ... This, however, still allows the electrons to move around the nucleus of an atom.
