Answer:
See the answer below
Explanation:
Aqueous solution of copper II nitrate contains solute of copper II nitrate dissolved in water. The equation for the reaction is as below:
[tex]Cu(NO_3)_2 (s)[/tex] + [tex]H_2O (l)[/tex] --> [tex]Cu(NO_3)_2 (aq)[/tex]
Hence, the solute chemical is copper II nitrate while the solvent is water.
Chemical formula of copper II nitrate - [tex]Cu(NO_3)_2[/tex]
Chemical formula of water - [tex]H_2O[/tex]
