4- Nazorat ishi
Nazorat ishi o’tkazilgan sana _________________ Mavzu:Eritma. Eruvchanlik. Nazorat shakli: Yozma ish. I-variant. 1.80gr 15%li eritmaga 20gr suv qo’shildi.Hosil bo’lgan eritmadagi moddaning massa ulushini (%) da aniqlang. 2 Eritma tarkibidagi erigan modda miqdoriga ko’ra eritmalar necha turga bo’linadi?3.300gr 20%li eritmadagi tuz va suvning massasini hisoblang.4. K2SO4 ning 40 oC dagi eruvchanlik koeffitsiyenti 64 ga teng. Shu haroratda to‘yingan eritma hosil qilish uchun 150 g K2SO4 ni necha gramm suvda eritish kerak? Kompetentlikni aniqlash uchun materiallar: 5.To’yingan va to’yinmagan eritmalarni misollar orqali tushuntirib bering. II-variant. 1. Moddalar suvda eruvchanligiga qarab qanday va necha guruhga bo‘linadi?2.120ml suvga 14,8gr magniy sulfat eritildi.Eritmadagi magniy sulfatning massa ulushini(%) da hisoblang.3. 6. Na2SO4 ning 30 oC dagi eruvchanlik koeffitsiyenti 50 ga teng. Shu temperaturada to‘yingan eritma hosil qilish uchun 100 g Na2SO4 ni necha gramm suvda eritish kerak? 4.Osh tuzini 100gr 10%li eritmasidagi tuz va suvning massasini hisoblang.Kompetentlikni aniqlash uchun materiallar: 5.Suyultirilgan va konsentrlangan eritmalarni hayotiy misollar orqali tushuntirib bering. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ ______________________________________________________________________________________________________________________________________________________________________________________________________ 5- Nazorat ishi Download 65.1 Kb.
