9-sinf o’quvchilari uchun masalalar

1. 30% li kaliy gidroksid eritmasi to’rtta qismiga bo’lindi va oddiy moddalar: alyuminiy, kremniy, oltingugurt, brom eritildi. Olingan eritmalarga asta-sekin 20% li xlorid kislota qo’shildi.

1) oddiy moddalarni ishqorda eritish reaksiya tenglamalarini yozing.

2) Ishqoriy eritmalarga kislota qo’shilganda paydo bo’ladigan reaktsiyalar tenglamalarini yozing.

3) Ortiqcha kislota qo’shilgandan keyin yuz beradigan o’zgarishlarni (rang, cho’kma) tavsiflab bering?

Yechimi:

2. 36,5 g vodorod xlorid va 40 g natriy gidroksid o’z ichiga olgan suvli eritmalarning o’zaro ta’siri davomida 57 kJ issiqlik ajralib chiqdi.

1) Ion reaktsiyasining to’liq va qisqartirilgan tenglamalarini yozing.

2) 150 g 10% sulfat kislota eritmasi va 50 g 11,2% kaliy gidroksid eritmasi o’zaro ta’sirida qancha issiqlik ajralib chiqadi?

Yechimi:

3. 300 K va 2 atm bosimdagi idishda 1 mol vodorod va 1 mol xlor mavjud. Aralash ultrabinafsha nurlar bilan yoritilgandan va reaksiya tugaganidan keyin idishning harorati 600 K ni tashkil etdi.

1) Reaksiya tenglamasini yozing.

2) Nega bu reaktsiya yoritilganda boshlanish sababini ko’rsating?

3) Yorug’lik ostida reaktsiyaning birinchi bosqichi qanday jarayon?

4) Reaksiya tugaganidan keyin haroratni o’lchashda idishda qanday bosim (atm) bo’lgan?

5) Reaksiya tugaganidan keyin idishda necha gramm vodorod xlorid hosil bo’ladi ?

Yechimi:

4. 69,8 g ishqoriy metallning karbonati va bikarbonati aralashmasi xlorid kislota bilan reaksiyaga kirishganda 30,8 g uglerod(IV) oksidi ajralib chiqadi. Asl aralashmada qaysi ishqoriy metal ekanligini va tuzlarning massalarini aniqlang.

Yechimi:

5. Zarg’aldoq rangli bo’yoqning qizil pigmenti – Surik qo’rg’oshin – Pb₃O₄ tarkibiga ega.

1. Ushbu birikmada qo’rg’oshinning oksidlanish darajasi qanday bo’lishi mumkin?

2. Ushbu moddani qaysi kimyoviy birikmalar sinfiga kiritish mumkin?

3. Surik ko’mir bilan o’zaro ta’sirlashganda metall qo’rg’oshin olinishi mumkin. Reaksiya tenglamasini yozing.

4. Nazariy jihatdan mumkin bo’lgan reaktsiya unumi 97% bo’lsa, 6,85 g Surikdan necha gramm qo’rg’oshin olish mumkin?

Yechimi:
