Quá trình cho e:
\(xF{e^{\frac{{ + 2y}}{x}}}\xrightarrow{{}}xF{e^{3 + }} + (3x - 2y){\text{ x(5n - 2m)}}\)
Quá trình nhận e:
\(n{N^{ + 5}} + (5n - 2m)e\xrightarrow{{}}n{N^{\frac{{ + 2m}}{n}}}{\text{ x(3x - 2y)}}\)
Cân bằng:
\((5n - 2m)F{e_x}{O_y} + (18nx - 6mx - 2ny)HN{O_3}\xrightarrow{{}}(5nx - 2mx)Fe{(N{O_3})_3} + (3x - 2y){N_n}{O_m} + (9nx - 3mx - ny){H_2}O\)
