Select the correct balanced net ionic equation for each of the following reactions, occuring in aqueous solution. Input the associated letter labels, in order (i)-(iii), no spaces, no commas. e.g. GBF

(i) 2HCl + Mg --> H2 + MgCl2
(ii) CuSO4 + CaCl2 --> CuCl2 + CaSO4
(iii) Cu(NO3)2 + Ni --> Cu + Ni(NO3)2

A. CuSO4 + Ca2+ --> Cu2+ + CaSO4
B. Mg + 2HCl --> Mg2+ + 2Cl- + H2
C. Cu2+ + Ni --> Cu + Ni2+
D. Ni + Cu2+ + 2NO3- --> Ni(NO3)2 + Cu
E. Ni + Cu2+ + 2NO3- --> Ni2+ + Cu + 2NO3-
F. Mg2+ + 2Cl- --> MgCl2
G. CaCl2 + Cu2+ --> Ca2+ + CuCl2
H. 2Cl- + Cu2+ --> CuCl2
I. Cu(NO3)2 + Ni --> Cu + Ni(NO3)2
J. 2H+ + Mg --> H2 + Mg2+
K. SO42- + Ca2+ --> CaSO4
L. none of the above
