Consider the molecular views of an Mg strip and Cu²+ solution. Mg. Cu2+ Part A Describe what happens to the atoms and ions after the Mg strip is submerged in the solution for a few minutes. O Several Mg atoms will dissolve into solution as Mg²+(aq), and several Cu?+ ions will deposit on the Mg surface as solid Cu. O Several Mg atoms will dissolve to generate Mg²+(aq), and several Cu²+(aq) ions will be reduced to Cu*(aq). O Several Mg atoms will dissolve into solution as Mg(aq), and several Cu2+ ions will deposit on the beaker surface as solid Cu. O Nothing happens, Mg strip and Cu²+(aq) will remain in the system.
