If you have a book, read it!! I promise you, it tells you this answer!
Answer:
Explanation:
Given:
A solution contains one or more of the following ions such as Ag, and
Here the Lithium bromide is added to the solution and no precipitate forms
Solution:
Since with LiBr no precipitation takes place therefore Ag+ is absent
Here on adding to it precipitation takes place.
Precipitate is as follows,
Thus,
is present
When is added again precipitation takes place.
Therefore the reaction is as follows,
Therefore,
are present in the solution
Neon-22 is the isotope with the greater mass.
P.S. When you have two isotopes of the same element, the one with the greater number will always have the greater mass
