(Solved): The reaction Zn(s)+Cu(NO3)2(aq)Zn(NO3)2(aq)+Cu(s) is a redox reaction where Cu( ...

The reaction $${\mathrm{Zn}}_{(s)}+\mathrm{Cu}{\left({\mathrm{NO}}_3\right)}_{2(aq)}{}^{\circledR }\mathrm{Zn}{\left({\mathrm{NO}}_3\right)}_{2(aq)}+{\mathrm{Cu}}_{(s)}$$ is a redox reaction where $$\mathrm{Cu}(\mathrm{II})$$ is reduced and $$\mathrm{Zn}$$ is oxidized is a precipitation reaction, but not an oxidation reaction is a substitution reaction, but not an oxidation reaction is a redox reaction where $$\mathrm{Cu}(\mathrm{II})$$ is oxidized and $$\mathrm{Zn}$$ is reduced can be used for analysis only, so the above situations do not apply
