Получение so2,h2so3,kcl,fe(oh)3,mg(oh)2,mgbr2

S + O2 = SO2

SO2 + H2O = H2SO3

K2SO4 + BaCl2 = 2KCl + BaSO4

FeCl3 + 3NaOH = 3NaCl + Fe(OH)3

Mg(NO3)2 + NaOH = NaNO3 + Mg(OH)2

MgSO4 + BaBr2 = BaSO4 + MgBr2

SO2 = S + O2

H2SO3 = SO2+H2O

KCl = 2K + Cl2

2FE(OH)3 = Fe2O3 + 3H2O

Mg(OH)2 = MgO + H2O

MgBr2 + BaSO4 = MgSO4 + BaBr2
