I need to know what kind of reactions and anything else you could tell me about these reactions... like observations etc. I think I have them balanced.

Na (s) + H2O(l)NaOh (aq) +H2(g)
Na  Na+ + e-
H2O + e- OH-
2Na + 2H2O  2(Na+ )(OH-) + H2

Ca + H2O(l)-CaO(s) + H2(g)
Ca  Ca+2 + 2e-
H2O + 2e-  O-2 + H2
Ca + H2O  (Ca+2)(O-2) + H2

Mg +H2O(l)-Mg (OH)2(aq) +H2(g)
Mg  Mg+2 + 2e-
H2O + e-  OH-
Mg + 2 H2O  (Mg+2)(OH-)2 + H2

Ni(NH4)2(SO4)2 +6H2O(s)NiSO4(s) + H2O(g) +NH3 (g) +H2SO4(g)
Ni(NH4)2(SO4)2 + H2O(s)  NiSO4(s) + H2O(g) + 2NH3 (g) +H2SO4(g)

Mg(s) +HCl(aq)H2(g) +MgCL2(aq)
Mg  Mg+2 + 2e-
2H+ + 2e-  H2
Mg + 2HCl  H2 + (Mg+2)(Cl-)2


Zn (s) +HCl (aq)H2(g) +ZnCl2(aq)
Zn  Zn+2 + 2e-
2H+ + 2e-  H2
Zn + 2HCl  H2 + (Zn+2)(Cl-)2

Cu(s) +AGNO3(aq)Ag(s) + Cu(NO3)2(aq)
Cu  Cu+2 + e-
Ag+ + e-  Ag
Cu + (Ag+)(NO3-)  Ag + (Cu+)(NO3-)2

Zn(s) + Pb(NO3)2(aq)-Pb(s) + Zn(NO3)2(aq)
Zn  Zn+2 + 2e-
Pb+2 + 2e-  Pb
Zn + (Pb+2)(NO3-)2  Pb + (Zn+2)(NO3-)2

Pb(NO3)2(aq) +KI(aq)Pbl2(s) +KNO3(aq)
(Pb+2)(NO3-)2 + 2(K+I-)  PbI2 + 2[ K+(NO3-)]

Fe(NO3)3(aq) + NaOH(aq)NaNO3(aq) +FE(OH)3(s)
(Fe+3)(NO3-)3 + 3[Na+OH-]  3[(Na+)(NO3-)] + Fe+3(OH-)3

CuSO4(aq) +NH3(aq)- Cu(NH3)4{+2}(aq) + SO4{-2(aq)
(Cu+2)(SO4)-2 + 4NH3  Cu(NH3)4{+2} + (SO4)-2
