Answer:
NaOCl + H2O → HOCl + NaOH
so the mole fraction is = moles of NaOCl/(moles of NaOCl+moles of H2O)
so for 1.35 NaOCl it will require 1.35 moleof H2O
mole fraction = 1.35/(1.35+1.35)
mole fraction = 1/2 =0.5
is it correct i d ek but i tried :)
Answer:
See answer below
Explanation:
To understand this, we need to make the reaction involved with the given configuration. Configuration R means that the substituents of the molecule, the priority order goes clockwise (From heaviest to lightest) so, if an Sn2 is ocurring in the reaction this means that the nucleophile, which in this case, is the sodium ethoxide will attack the molecule in the opposite side of the leaving group (which is the chlorine).
Also when this occurs, as Sn2 is a bimolecular reaction and is held in one step, it occurs an inversion in the configuration of the product. So, it's the innitial reactant was R, then the final product will be S.
The mechanism and product can be watched in the attached picture
Hope this helps.
Answer:
C) When electrons change levels to produce the Balmer series, the emitted light is in the visible part of the spectrum
Explanation:
The Balmer Series of lines in the hydrogen atom was very important in the history of physics and astronomy. What made it so important?
A) It helped Rutherford explain the workings of the atomic nucleus.
B) Balmer's experiments with these lines helped prove Wien's Law.
C) When electrons change levels to produce the Balmer series, the emitted light is in the visible part of the spectrum.
D) The Balmer series of lines can only be observed from outer space; so the competition to see these lines led to the space race.
E) Mr. Balmer never got the Nobel prize, which made everyone in the field of spectroscopy so angry, they worked extra hard.
the most appropriate will be
C) When electrons change levels to produce the Balmer series, the emitted light is in the visible part of the spectrum
Balmer series of hydrogen lines. These lines are emitted when the electron in the hydrogen atom moves from the orbital n = 3 or greater shell down to the n = 2 shell/orbit. ... Energy is emitted from the atom when the electron leaps from one orbit to another closer to the nucleus.
Wiens law has to do with the radiation of a black body.
