Question

In the experiment Chemistry of Copper we started out with pure Copper and then did the synthesis of:
Cu(NO3)2 (aq)
Cu(OH)2 (s)
CuO (s)
CuSO4 (aq)

Copper (II) sulfate to copper metal. Write a full description of the reaction that occured. Include a balanced equation.

Answer 1

You have to write the equations for the reactions you have used. Here is only a proposal:

                                               

Cu (s) + 4 HNO3 (aq) → Cu(NO3)2 (aq) + 2 NO2 (g) + 2 H2O (l)
Cu(NO3)2 (aq) + 2 NaOH (aq) → Cu(OH)2 (s) + 2 NaNO3 (aq)
Cu(OH)2 (s) →CuO (s) + H2O (g)

CuO (s) + H2SO4 (aq)→ CuSO4 (aq) + H2O (l)
CuSO4 (aq) + Mg (s) → Cu (s) + MgSO4 (aq)
