осуществите превращения
K⇒K₂O⇒KOH⇒KI
S⇒SO₂⇒H₂SO₃⇒ZnSO₃
Mn⇒MnO⇒Mn(OH)₂⇒MnBr₂
N⇒N₂O₅⇒HNO₃⇒Fe(NO₃)₃

Answers & Comments

IrVB 1) 4K + O2 = 2K2O
K2O + H2O = 2KOH
KOH + HI = KI + H2O

2) S + O2 = SO2
SO2 + H2O = H2SO3
H2SO3 + ZnCl2 = ZnSO3 + 2HCl

3) 2Mn + O2 = 2MnO
оксид марганца в воде не растворяется, поэтому напрямую получить гидроксид нельзя
MnO + 2HCl = MnCl2 + H2O
MnCl2 + 2KOH = Mn(OH)2 + 2KCl
Mn(OH)2 + 2HBr = MnBr2 + 2H2O

4) 2N2 + 5O2 = 2N2O5
N2O5 + H2O = 2HNO3
3HNO3 + Fe(OH)3 = Fe(NO3)3 + 3H2O
