Answer:
Heating is the best method
Explanation:
When a mass of crystals containing Water of crystallization is heated sufiiciently to a high temperature, water vapor may be driven off the crystals by the action of heat alone.
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,
Ni(s) + Cu(NO₃)₂(aq) --> Cu(s) + Ni(NO₃)₂(aq)
The phases are also written in the equation.
