MgCl2 aq plus Zn s is the oxidation half-reaction for Mg s plus ZnCl2 aq.
Mg(s)—-> Mg2+ + 2e-
Absallutly!
Cu and ZnCl2 are being produced.
3 MgCl2 + N2 = Mg3N2 + 3 Cl2
water [H20]
single replacment

-1.68 V
Mg + MgCl2
Cu and ZnCl2 are being produced.
The type of reaction represented by Zn plus 2NaCl yields 2Na plus ZnCl2 is an impossible one. It would be the other way around. 2Na + ZnCl2 --------> 2NaCl + Zn
The net ionic equation is Zn + 2H+ --> Zn2+ + H2
3 MgCl2 + N2 = Mg3N2 + 3 Cl2
No reaction
2
CuCl2
The balanced equation is as follows: Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g)
