I believe the correct answer would be E. When aqueous solutions of NiBr 2 and AgNO3 are mixed, a precipitate forms. As these two solutions are being mixed a reaction would happen resulting to two new compounds which are nickel nitrate and silver bromide. The reaction would be:
NiBr2 + AgNO3 = NiNO3 + AgBr2
The precipitate that would be formed would be the silver bromide since most of the silver compound are not or has low solubility in water while most of the nitrate compounds are very soluble in water. Most likely, it would be the silver bromide that is the precipitate.
It is the beginning stage
