7-sinf laboratoriya ishlari

Nazorat uchun savollar:

  1. Oksidlarning tasnifini tushuntirib bering.

  2. Oksidlarning yana qanday agregat holatlari mavjud?

  3. Ushbu oksidlarning (ZnO; Fe203; CuO) suvda erishi haqida nimalarni bilasiz?

4- Laboratoriya ishi: YOQILG4NING TURLI XILLARI VA ULARDAN UNUMLI FO DALANISH USULLARI BILAN TANISHISH.
M aqsad: yoqilg'i turlari bilan tanishtirish, inson hayotida yoqilg'ining ahamiyati, sanoat va qishloq xo'jaligida tutgan o'rni haqida tushuncha berish.
Reaktivlar: yog'och, faollashgan ko'mir namunasi.
O'quv-ko'rgazmali qurollar: «Ko'mirning ko'kslash mahsulotlari», «Neft va neft mahsulotlari» kolleksiyalari.
«Neft va neft mahsulotlari» kolleksiyalari Ko'mirning ko'kslash mahsulotlari
lshni bajarish tartibi:
  1. Berilgan har xil yoqilg'i namunalari diqqat bilan ko'zdan kechiriladi, berilgan yoqilg'ilarning fizik xossalarini ifodalovch jadvalini tuzib mustaqil tarzda to'ldiriladi.
