Complete the balanced reaction if it will occur.
State "does not occur" if the reaction will not take place.

3Na + 4 HNO3 = 3NaNO3 + 2H20 + NO
(will take place because Na has the higher oxidation potential)
Ni + CuO = NiO + Cu
(will take place because Ni has a higher oxidation potential)
Zn + Mg(NO3)2 = Zn(NO3)2 + Mg
(will not take place because Zn has a lower oxidation potential)

2Na + 2HNO3 ---> 2NaNO3 + H2
Ni + Cu2O ---> not possible because copper is more reactive than Nickel
Zn + Mg(NO3)2 ----> Not possible because magnesium is more reactive than zinc
