Is gazi (CO) va karbonat angidrid (CO₂) aralashmasida CO₂ dagi elektronlar miqdori CO dagi elektronlar miqdoridan 1 molga ko‘p. Aralashma ohakli suvdan o‘tkazilganda hosil bo‘lgan cho‘kma ajratib olindi va qizdirilganda 16,8 g qattiq qoldiq hosil bo‘ldi. Dastlabki gazlarning mol miqdorlari farqini aniqlang.

📝 Detailed explanation

CO – 14 ē, CO₂ – 22 ē. Tenglama: 22b − 14a = 1, bunda a=n(CO), b=n(CO₂). Faqat CO₂ CaCO₃ hosil qiladi; CaCO₃→CaO (56 g/mol), 16,8/56 = 0,3 mol ⇒ b = 0,3. 22·0,3 − 14a = 1 ⇒ a = (6,6 − 1)/14 = 0,4. |b − a| = |0,3 − 0,4| = 0,1.
