since the powers 3+ = 3-
the cancel each other out so the formula becomes
FeN
hope this helped.
FeCl3
n3 + 1 = n3 + 13 = (n + 1)(n2 - n + 12) = (n + 1)(n2 - n + 1)
Zn(s) → Zn2+(aq) + 2e- and Fe3+(aq) + e- → Fe2+(aq)
Let any number be n:- n3/n3 = n*n*n/n*n*n = 1 And in index form: n3/n3 = n3-3 = n0 = 1
n2+n3=n5 it's simple 8th grade pre-algebra
FeCl3
n3 + 3n2 + 4n + 12 = (n3 + 3n2) + (4n + 12) = n2(n + 3) + 4(n + 3) = (n2 + 4)(n + 3).
n3 + 1 = n3 + 13 = (n + 1)(n2 - n + 12) = (n + 1)(n2 - n + 1)

b. Fe3 plus ions
6+N3 is the sum of N*3 then you add six. 6*N3 is you multiply 6 times three times N times three.
Al3 plus and N3 combine ionically -well neither species exist but aluminum and nitrogen combine to make aluminum nitride - AlN.
When 90.0mL of 0.10M Fe3 plus 3 is added to 10.0 mL of SCN minus 1, you get an equilibrium molar concentration of FeNCS plus 2. This is determined from a calibration curve of 1.0x10-6 mol/L.

Hg will have 80 electrons.
FeBr2 + H3PO4 <--> Fe3(PO4)2 + HBr
FeSO4 + K3PO4 ---> Fe3(PO4)2 + K2SO4
