NH4^ so N is -3 (because H is 1 that means -3 4 = 1)

Mn = 2

N = 5

O = -2

Mn No3 2

NH4^ so N is -3 (because H is 1 that means -3 4 = 1)

O is 2- so you have -14 for O 2 for NH4^ and 2 something for Cr

-14 2 2x = 0 (the compound is neutral)

so from that you get that Cr is 6

Mn No3 2

Mn = 2

N = 5

O = -2
