1) $C_{x}$$H_{y}$ +$H_{2}$$SO_{4}$ → $SO_{2}$ + $CO_{2}$ + $H_{2}$O
2) $Fe_{x}$$O_{y}$ + $H_{2}$$SO_{4}$ → $Fe(NO_{3})$$_{3}$ +S + $H_{2}$O
3) M + $HNO_{3}$ → $M(NO_{3})$$_{n}$ +NO + $H_{2}$0
4) $M_{x}$$O_{y}$ + $HNO_{3}$ → $M(NO_{3})$$_{n}$ +NO + $H_{2}$0
5) $Fe_{x}$$O_{y}$ + $O_{2}$ → $Fe_{n}$$O_{m}$
