Can someone explain this to me please 
Select the correct balanced net ionic equation
for each of the following reactions, occuring
in aqueous solution.
1) Cu(NO3)2 + Ni Cu + Ni(NO3)2
2) (NH4)2SO4 + 2NaBr Na2SO4 + 2NH4Br
3) 2HCl + Mg H2 + MgCl2
A.Mg2+ + 2Cl- MgCl2
B.Ni + Cu2+ + 2NO3- Ni2+ + Cu + 2NO3-
C.SO42- + 2Na+ Na2SO4
D.Cu(NO3)2 + Ni Cu + Ni(NO3)2
E.Ni + Cu2+ + 2NO3- Ni(NO3)2 + Cu
F.(NH4)2SO4 + 2Br- 2NH4Br + SO42-
G.2NH4+ + 2Br- 2NH4Br
H.no reaction
I.2HCl 2Cl- + H2
J.Ni + Cu2+ Ni2+ + Cu
K.Mg + 2HCl Mg2+ + 2Cl- + H2
L.none of the above
