Answer:
The overall change in the oxidation number of sulfur is 8.
Explanation:
Oxidation number is defined number assigned to an element in reaction which represent the loss or gain of electrons by an atom of an element in a compound.
In
let the oxidation number of S in hydrogen sulfide be x.
x = -2
In
let the oxidation number of S in sulfate ion be x.
x = -2 + 8 = +6
The overall change in the oxidation number of sulfur :
= [+6] - [-2] = 8
Answer:
Explanation:
Part two of Dalton's theory had to be modified after mass spectrometry experiments demonstrated that atoms of the same element can have different masses because the number of neutrons can vary for different isotopes of the same element. ... Scientists have even developed the technology to see the world on an atomic level!
