\(Fe_xO_y+HNO_3\rightarrow Fe\left(NO_3\right)_3+NO+H_2O\)
\(\overset{\frac{+2y}{x}}{3FexOy}+\overset{^{+5}}{\left(12x-2y\right)HNO3}\rightarrow\overset{^{+3}}{3xFe\left(NO3\right)3}+\overset{^{+2}}{\left(3x-2y\right)NO}+\left(6x-y\right)H2O\)
\(3y+36x-6y\) _______________\(27x+3x-2y+6x-y\)
\(36x-3y=36x-3y\)
