Закінчити рівняння можливих реакцій: 1. Cr + CuSO4 = 2. Ni + AlCl3 = 3. Fe + AgNO3 = 4. Pb + Hg(NO3)2 = 5. Sn + ZnBr2 = 6. Cu + HgCl2 =

Answer 1

Ответ:

1. 2 Cr + 3 CuSO4 → Cr2(SO4)3 + 3 Cu

2.  3Ni + 2AlCl3 → 3NiCl2 + 2Al

3. Fe + 2 AgNO3 → 2 Ag + Fe(NO3)2

4. Hg + Pb(NO3)2 = Pb + Hg(NO3)2

5.  Zn + SnBr2 → ZnBr2 + Sn

6. Cu + HgCl2 = CuCl2 + Hg
