C помощью каких реакций можно осуществить превращения?! S - H2S - S - SO2 - Na2SO3 - SO2 - SO3?
H2 + S = H2S 2H2S + O2 = 2S↓ + 2H2O S + O2 = SO2 SO2+2NaOH=Na2SO3+H2O Na2SO3+ N2O5=SO2+2NaNO3 2SO2+O2=2SO3

H2 + S = H2S
2H2S + O2 = 2S↓ + 2H2O
S + O2 = SO2
SO2+2NaOH=Na2SO3+H2O
Na2SO3+ N2O5=SO2+2NaNO3
2SO2+O2=2SO3
