Quyidagi reaksiyalar eng kichik butun sonlar bilan tenglashtirilganda, suv (H₂O) oldidagi koeffitsiyentlarni o‘zaro taqqoslang.
a) H₂S + HNO₃ → S + NO + H₂O
b) MnO₂ + HBr → MnBr₂ + Br₂ + H₂O
c) H₂S + SO₂ → S + H₂O
a < c < b
b = c < a
c < b < a
b < a < c
📝 Detailed explanation
a) 3H₂S+2HNO₃→3S+2NO+4H₂O ⇒ 4. b) MnO₂+4HBr→MnBr₂+Br₂+2H₂O ⇒ 2. c) 2H₂S+SO₂→3S+2H₂O ⇒ 2. Demak b = c < a.
