Hisoblash: Barcha yoqilgan yoqilg'ini toza uglerod deb taxmin qilamiz. Uning miqdori yonish koeffitsienti bilan yoqilg'i massasi mahsuloti bilan aniqlanadi:
(1.5)
yoki
Yoqilg‘ini yonishi parallel holda ikkita jarayonda boradi:
(1.6)
(1.7)
Karbonad angidrid bir qismi cho‘g‘langan ko‘mir bilan ikkilamchi reaksiyaga kirishadi:
(1.8)
(1.6) da keltirilgan reaksiyada qatnashadigan uglerodning massasi quyidagiga teng:
(1.9)
yoki
(1.7) da keltirilgan reaksiyada qatnashadigan uglerodning massasi quyidagiga teng:
(1.10)
yoki
CO ni hosil qiluvchi uglerodning umumiy massasi quyidagiga teng:
(1.11)
yoki
Osonlashtirish maqsadida is gazini hosil bo‘lish jarayonini (1.7) dagi reaksiya bo‘yicha olib borilmoqda deb hisoblaymiz. Kimyoviy reaktsiyaga jalb qilingan massalarning nisbati asosida (1.1-vazifani echish uchun tushuntirishlarga qarang), hosil bo’lgan uglerod oksidining massasini topamiz.
(1.12)
yoki .
(CO ni molekular og‘irligini uglerod va kislorod atom og‘irligi yig‘indisidek topamiz; (1.7) tenglamadagi CO va C dan oldingi koeffitsientlar bir-birini bekor qiladi).
Normal sharoitlarda ushbu miqdordagi uglerod oksidi olinadigan hajm qo’yidagich hisoblanadi:
yoki 4,480 m3.
(CO ning bir mol massasi - 0,028 kg; normal sharoitda bir mol gaz egallagan hajmi - 22,4 litr, 1.1 vazifani echish uchun tushuntirishlarga qarang).
Birlashtirilgan gaz qonunining tenglamasiga binoan biz T = 313K darajasida uglerod oksidining haqiqiy hajmini topamiz:
(1.13)
Bu yerda
Xonaning maydoni
Uglerod oksidi bilan to'ldirilgan zonaning balandligini aniqlaymiz:
Ko‘rinib turibtiki xonada is gazi miqdori meyordan yuqori yoki
Javob: uglerod oksidi bilan to'ldirilgan zona 2,375 metrdan yuqori.
