Explanation:
C. Precipitate the crystals as fast as possible
Precipitation if done fast , can lead to the formation of impure crystals , as impurities also get stuck inside the crystals. So it must be done slowly to obtain the pure crystals . Slower the crystals form , purer they are .
All the other options can lead to a successful recrystallization.
Answer:
C
Explanation:
The electrons in an atom are specifically housed in locations that could be referred to as shells. These shells are the places where we can find an electron.
Now, within each shell, we have different energy levels in which these occupants electrons occupy. These energy levels have different energies and the amount of electrons they can take.
For example, the number of electrons S can take is 2 while that in which d can take is 10
