расставить коэффициенты
1. S + 02= So2
2. So2+H2O=H2So3
3. H2So3+NaOH= Na2So3+H2O
4. S+H2=H2S
5. H2S+2KOH=K2S+2H2O
6. FeS+2HCL=FeCl2+H2S (стрелочка вверх)
7. 2FeS+3O2= 2FeO+2S02
8. 2H2S+02=2S+2H2O
9. 2H2S+4HClO3= 3H2SO4+4HCl
10. Hg+S=HgS
11. 2So2+O2= 2So3
12. So2+2NaOH=Na2So3+H20
13. H2SO3+ So2=So2+H2O
14. H2So3+Br2+H2O=H2So4+2HBr
15. Na2So3+H2So4=Na2So4+So2+H2O
16. So3+H2O=H2So4
17. 2Al(OH)3+3H2SO4=Al2(SO4)3+6H20
18. CuSo4+H2S=CuS(стрелочка вниз)+ H2SO4
19. CuSo4+H2S=Cus(стрелочка вниз)+H2So4
20. Na2S+H2So4=Na2So4+H2S
помогите пж!​
