of copper and do the following chemical reactions: 1. Dissolve the copper metal and make copper (II) ion: When nitric acid is added to copper metal, each copper atom gives 2 electrons to the 2 nitrogens in nitric acid: Molecular equation: Cu(s) + 4HNO3(aq) à 2NO2 (g) + Cu(NO3)2 (aq) + 2H2O(l) Ionic Equation:...
