A
Copper (Cu)
B
Zinc (Zn)
C
Gold (Au)
D
Silver (Ag)
Verified step by step guidance1
Understand that a single displacement reaction occurs when a more reactive metal displaces a less reactive metal from its compound.
Refer to the activity series of metals, which ranks metals based on their reactivity from highest to lowest.
Locate nickel (Ni) on the activity series to determine its relative reactivity.
Compare the positions of copper (Cu), zinc (Zn), gold (Au), and silver (Ag) relative to nickel (Ni) in the activity series.
Identify that only metals above nickel in the activity series, such as zinc (Zn), can displace nickel from NiSO_4 in a single displacement reaction.
