Question

What the net ionic reaction for zn+mg(no3)2, fe +mg(no3)2, cu+mg(no3)2,Al+mg(no3)2, Fe+Zn(no3)2 , Cu+Zn(no3)2, Cu+Fe(no3)3

Answer 1

1. zn+mg(no3)2, :

Zn (s) + Mg(NO3)2 (aq) --- > Zn(NO3)2 (aq) + Mg (s)

Zn (s) + Mg2+ (aq) + 2(NO3)- (aq) --- > Zn2+ (aq ) 2(NO3)- (aq) + Mg (s)

The net ionic reaction:

Zn (s) + Mg2+ (aq) -- > > Zn2+ (aq ) + Mg (s)

2.

fe +mg(no3)2,

Fe (s) + Mg(NO3)2 (aq) --- > Fe(NO3)2 (aq) + Mg (s)

Fe(s) + Mg2+ (aq) + 2(NO3)- (aq) --- > Fe2+ (aq ) 2(NO3)- (aq) + Mg (s)

The net ionic reaction:

Fe (s) + Mg2+ (aq) -- > > Fe2+ (aq ) + Mn (s)

3.

cu+mg(no3)2,

Mg(2+) +2NO3(-) + Cu --- > Cu(2+) +2NO3(-) + Mg

NO3(-) present on both sides so the net equation is

Cu(s) + Mg2+ -> Mg(s) + Cu2+

4. Al+mg(no3)2,

2 Al (s) + 3 Mg(NO3)2 (aq)--- . 2 Al(NO3)3 (aq) + 3 Mg (s)

2 Al (s) + 3 Mg2+(aq) + 6(NO3)- (aq) -- > 2 Al3+ (aq) + 6(NO3)- (aq) + 3 Mg (s)

2 Al (s) + 3 Mg2+(aq) --- >2 Al3+ (aq) +3 Mg (s)
