Nickel is the 28th chemical in the periodic table and the chemical symbol of copper (II) nitrate is Cu(NO₃)₂. The chemical reaction that occurs between these compounds is a single-replacement reaction.
From the activity series of metals, nickel is able to replace copper in the compound and this is expressed in the balanced equation,
