Химия: S- so2- h2so3- h2so4- znso4- zns- h2s- so2- so3- h2so4- baso4

Elenawow · Answer

S+O2=SO2

SO2+H2O=H2SO3

H2SO4+2NaOH=Na2SO4+2H2O

5H2SO4+4Zn=4ZnSO4+H2S+4H2O

ZnSO4 + Na2S = ZnS + Na2SO4

ZnS + 2 HCl = ZnCl2 + H2S

2H2S + ЗО2 = 2Н2О + 2SO2

2SO2+O2= 2SO3

S03+H2O=H2SO4

H2SO4+BaCL2= BaSO4+2HCL

S-> so2-> h2so3-> h2so4-> znso4-> zns-> h2s-> so2-> so3-> h2so4-> baso4
