Etil spirti va uchlamchi butil spirti aralashmasi CuO bilan reaksiyaga kirishganda 16 g mis hosil bo‘ldi. Xuddi shunday miqdordagi aralashma yondirilganda esa 0,9 mol CO₂ ajraldi. Dastlabki aralashmadagi uchlamchi butil spirtining miqdorini (mol) toping.

📝 Detailed explanation

Uchlamchi spirt CuO bilan oksidlanmaydi. n(Cu)=16/64=0,25 mol ⇒ n(C₂H₅OH)=0,25 mol. Yonish: 2C₂H₅OH→4CO₂, C₄H₉OH→4CO₂. n(CO₂) = 2·0,25 + 4·y = 0,9 ⇒ y = 0,1 mol.
