Muammoni hal qilishning misollari

Vazifa	5 tonna ammiakli selitrani olish uchun ammiakning massasi va hajmi qancha bo'ladi?
Qaror	Ammiak va nitrat kislotadan ammiakli selitrani olish reaksiya tenglamasini yozamiz: NH 3 + HNO 3 \u003d NH 4 NO 3 Reaksiya tenglamasiga ko'ra, ammiakli selitra moddasining miqdori 1 mol - v (NH 4 NO 3) \u003d 1 mol. Keyin reaksiya tenglamasi bilan hisoblangan ammiakli selitraning massasi: m (NH 4 NO 3) \u003d v (NH 4 NO 3) × M (NH 4 NO 3); m (NH 4 NO 3) \u003d 1 × 80 \u003d 80 t Reaksiya tenglamasiga ko'ra ammiak moddasining miqdori ham 1 mol - v (NH 3) \u003d 1 mol. Keyin tenglama bilan hisoblangan ammiak massasi: m (NH 3) \u003d v (NH 3) × M (NH 3); m (NH 3) \u003d 1 × 17 \u003d 17 t Keling, mutanosiblik va ammiak massasini topaylik (amaliy): x g NH 3 - 5 t NH 4 NO 3 17 t NH 3 - 80 t NH 4 NO 3 x \u003d 17 × 5/80 \u003d 1.06 m (NH 3) \u003d 1,06 t Ammiak hajmini topish uchun shunga o'xshash nisbatni tuzamiz: 1,06 g NH 3 - xl NH 3 17 t NH 3 - 22,4 × 10 3 m 3 NH 3 x \u003d 22.4 × 10 3 × 1.06 / 17 \u003d 1.4 × 10 3 V (NH 3) \u003d 1,4 × 10 3 m 3
Javob	Ammiak massasi - 1,06 t, ammiak hajmi - 1,4 × 10 m

AMMONIYA [yunoncha qisqacha? MkΜiap? Σ; Lotin sal ammiak; Liviya cho'lidagi Ammoniy vohasida tuya go'ngi yoqish natijasida olingan ammiak (ammoniy xlorid) nomi ham shunday bo'lgan] azotning vodorod bilan eng oddiy kimyoviy birikmasi, NH 3; kimyo sanoatining yirik tonajli mahsuloti.
