[nga Ngô]

Viết các quy tắc hóa trị:

VD: BaCO₃ => QTHT: 1 x II = 2 x I

1. Fe(OH)₂

2. Fe(OH)3

3. Cu(NO₃)₂

4. CuCl₂

5. Al₂O₃

6. Al(NO₃)₃

7. ZnSO₄

8. AgNO₃

9. Mg(PO₄)₂

Answer 1

[Minh Nhân]

1. Fe(OH)2 => II*1 = I*2

2. Fe(OH)3 => III*1 = 3*I

3. Cu(NO3)2 => II*1 = I*2

4. CuCl2 => II*1 = I*2

5. Al2O3 => 2*III = 3*II

6. Al(NO3)3 => III*1 = 3*I

7. ZnSO4 => II*1 = II*1

8. AgNO3 => 1*I = 1*I

9. Mg3(PO4)2 => II*3 = III*2
