aluminum + nickel(II) sulfate --> aluminum sulfate + nickel
2Al + 3Ni(SO4) --> Al2(SO4)3 + 3Ni

ammonium phosphate + magnesium nitrite --> magnesium phosphate +ammonium nitrite
2(NH4)3(PO4) + 3Mg(NO2)2 --> Mg3(PO4)2 + 6(NH4)(NO2)

lead + nitrogen --> lead(IV) nitride
3Pb + 2N2 --> Pb3N4

Answer 1

For aluminum + nickel(II) sulfate --> aluminum sulfate + nickel:

Al + NiSO4 --> Al2(SO4)3 + Ni

Using the tally method:

Al: 2

Ni: 1

S: 3

O: 12

The balanced equation is:

2Al + 3Ni(SO4) --> Al2(SO4)3 + 3Ni

For ammonium phosphate + magnesium nitrite --> magnesium phosphate + ammonium nitrite:

(NH4)3PO4 + Mg(NO2)2 --> Mg3(PO4)2 + 6NH4NO2

Using the tally method:

N: 6

H: 28

P: 2

O: 16

Mg: 3

The balanced equation is:

2(NH4)3(PO4) + 3Mg(NO2)2 --> Mg3(PO4)2 + 6(NH4)(NO2)

For lead + nitrogen --> lead(IV) nitride:

3Pb + 2N2 --> Pb3N4

Using the tally method:

Pb: 3

N: 8

The balanced equation is:

3Pb + 2N2 --> Pb3N4
