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
