1️⃣ 200 g 34% li AgNO₃ eritmasiga 10 g mis plastinka tushirildi. Birmuncha vaqt oβ€˜tgach, plastinka eritmadan chiqarib olindi va hosil boβ€˜lgan eritma toβ€˜liq elektroliz qilindi. Elektroliz jarayoni yakunlangach, katodda 28 g massali metallar aralashmasi hosil boβ€˜ldi.
33. Elektroliz jarayonida ajralgan kislorod massasini (g) aniqlang.
34. Eritmadan chiqarib olingan plastinkada qolgan mis massasini (g) aniqlang.
35. Plastinkaga ajralib chiqqan kumush massasini (g) aniqlang.

Javob: 33) 3,2; 34) 3,6 g; 35) 21,6 g
