We are asked if a reaction occurs when an aqueous solution of NiCl2(aq) is added to a test tube containing strips of metallic zinc.


According to solubility rules:
Cl-, Br-, and I- are soluble except when paired with Ag+, Pb2+, Cu+, Hg22+ 


So  NiCl2(aq) dissociates as: 

NiCl2(aq) → Ni2+(aq) + Cl-(aq)
