Answer 1

a)\(3M+4nHNO_3-->3M\left(NO_3\right)_n+nNO+2nH_2O\)

b)

\(2M+2nH_2SO_4-->M_2\left(SO_4\right)_n+nSO_2+2nH_2O\)

c)

\(8M+30HNO_3-->8M\left(NO_3\right)_3+3N_2O+15H_2O\)

d)

\(8M+10nHNO_3-->8M\left(NO_3\right)_n+nN_2O+5nH_2O\)

e)\(\left(5x-2y\right)Fe+\left(15x-3y\right)HNO_3-->\left(5x-2y\right)Fe\left(NO_3\right)_3+3N_xO_y+\left(\dfrac{15x-3y}{2}\right)H_2O\)

Answer 2

f) \(3Fe_xO_y+\left(6x+2y\right)HNO_3-->3xFe\left(NO_3\right)_3+\left(2y-3x\right)NO+\left(3x+y\right)H_2O\)

g)\(Fe_xO_y+\left(6x-2y\right)HNO_3-->xFe\left(NO_3\right)_3+\left(3x-2y\right)NO_2+\left(3x-y\right)H_2O\) h)\(Fe_xO_y+2yHCl-->xFeCl_{\dfrac{2y}{x}}+yH_2O\)

i)\(2Fe_xO_y+2yH_2SO_4-->xFe_2\left(SO_4\right)_{\dfrac{2y}{x}}+2yH_2O\)
