Sariq rangli qattiq A oddiy modda konsentrlangan sulfat kislota bilan ta’sirlashsa o‘tkir hidli B gaz hosil bo‘ladi (quruq turshak tayyorlashda ishlatiladi). B gaz boshqa bir C gaz bilan reaksiyaga kirishib A modda va murakkab D moddani hosil qiladi. Barcha reaksiya tenglamalaridagi A, B, C, D moddalar oldidagi koeffitsiyentlar yig‘indisini hisoblang.

📝 Detailed explanation

A — oltingugurt (S); B — SO₂; C — H₂S; D — H₂O. Reaksiyalar: S+2H₂SO₄→3SO₂+2H₂O va SO₂+2H₂S→3S+2H₂O. Koeffitsiyentlar yig‘indisi: 1+2+3+2 + 1+2+3+2 = 14.
