Part A: Cu(s) + 4HNO3(aq) → Cu(NO3)2(aq) +2H2(g) + 2NO2(g)
Double replacement because the copper and the Hydrogen switched

Part B: Cu(NO3)2(aq) +2NaOH(aq) → Cu(OH)2(s) + 2NaNO3(aq)
NaOH(aq) + HNO3(aq) → NaNO3(aq) + H2(l)



This is a Double Replacement Percipitation Reaction because there is a formation of a solid, which is the driving force in this reaction.





Part C: Cu(OH)2(s)→ CuO + H2O(l)
Decomposition, and redox, because copper and hydroxide broke up.








Part D: Cu(s) + 2HCL(aq) → CuCL(aq) + H2O(l)
Double Replacement, because copper and hydrogen switched places.




Part E: 3CuCl2(aq) + 2Na3PO4(aq) → Cu3(PO4)2(s) + 6 NaCl(aq)
percipitation, double replacement, because the copper and sodium switch. copper and phosphate make a solid ( percipitate).




*This reaction was also a Double replacment Percipitation Reaction. The driving force in this reaction was the formation of a solid, Cu3(PO4)2.








NaOH(aq) + HCL(aq) → NaCl(aq) + H2O(l)







Part F: Cu3(PO4)3(s) + 3H2SO49aq) → 3CuSO4(aq) + 2H3PO4(aq)
Double Replacement.








Part G: Zn(s) + CuSO4(aq) → ZnSO4(aq) + Cu(s)
Single replacement, because the SO4 is being replaced by Zn and the driving force is the copper forming.

Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g)

single replacement, the Zn is replacing the H2.
