Question

Уравнение реакции S-so2-h2so3-k2so3

Ba-BaO-ba(oh)2-baso4

Answer 1

S+O2-->SO2
SO2+H2O-->H2SO3
H2SO3+2KOH-->K2SO3+H2O

2Ba+O2-->2BaO
BaO+H2O-->Ba(OH)2
Ba(OH)2+H2SO4-->BaSO4+2H2O

Answer 2

S + O2 -> SO2
SO2 + H2O -> H2SO3
H2SO3 + K2O -> K2SO3 + H2O

2Ba + O2 -> 2BaO
BaO + H2O -> Ba(OH)2
Ba(OH)2 + H2SO4 -> BaSO4↓ + 2H2O
