Out of mercury, brine, and bromine.
It is Brine which will leave behind a residue when heated and evaporated.
This is because mercury is metal and bromine is an element but brine is a solution of salt in water, and when it is burned, the salt is left behind as a residue which can be easily seen.
Brine is not a pure element.
