It doesn't.
They could, since magnesium is more reactive than copper, and could displace it to form magnesium nitrate.
It forms copper oxide
by electrolysis(molten or aqueous they are the same in results)
Yes, this reaction is possble.
For example the nitric oxide (NO2) extracted by the thermal decomposition of a nitrate (as copper nitrate) is passed through water.
The chemical formula for copper (I) nitrate is CuNO3.
copper oxide, nitrogen and oxygen
They could, since magnesium is more reactive than copper, and could displace it to form magnesium nitrate.
copper (thiocyanate)2 and potassium nitrate
Copper nitrate dissolves in water, hence it is a chemical reaction.
copper nitrate
copper nitrate and water
no
oxygen
It forms copper oxide
By dissolving the silver nitrate in water, then stirring finely divided copper into the water. The copper will displace silver from the silver nitrate as a solid and form copper nitrate in the solution.
heating of copper nitrate at 200 degree yields copper oxide
