The physical state of the reactants and products are shown by writing the symbols after each reactant and product in the reaction. The symbol “l” represents liquid, “aq” represents aqueous, “s” represents solid, and “g” represents gas.
The reaction taking place by keeping a piece of pure zinc metal into a solution of copper(II) sulfate is written as:
The reaction is already balanced as the number of each atom of each element on both the sides of the equation is same.
The chemical equation is:
