Question

It is your task to develop a cycle of reactions involving copper that begins with the use of elemental copper and ends with the production of elemental copper. Shown below are the 4 reactions involved in the Cu cycle listed in random order.

Cu3(PO4)2(s) + HCl(aq) CuCl2(aq) + H3PO4(aq)

CuCl2(aq) + Mg(s) MgCl2(aq) + Cu(s)

Cu(s) + 4 HNO3(aq) Cu(NO3)2(aq) + 2 NO2(g) + 2 H2O(l)

Cu(NO3)2(aq) + Na3PO4(aq) Cu3(PO4)2(s) + NaNO3(aq)

Balance the 4 equations if needed, then place them in the proper order such that the first reaction starts with elemental copper, the 2nd reaction starts with the products of the first, and so on until the 4th reaction ends with the production of elemental copper. (Include states-of-matter under the given conditions in your answer. Use the lowest possible whole number coefficients.)
