Question

CU(OH)₂---->CuSO_{4 ----->}CuCl₂-------->Cu(NO₃)₂ ----->Al(NO₃)3------>Al(OH)₃------->Al₂O₃

Answer 1

(1) Cu(OH)₂ + MgSO₄ → CuSO₄ + Mg(OH)₂

(2) CuSO₄ + BaCl₂ → CuCl₂ + BaSO₄

(3) CuCl₂ + 2 AgNO₃ → Cu(NO₃)₂ + 2 AgCl

(4) 3Cu(NO₃)₂ + 2Al → 2Al(NO₃)₃ + 3Cu

(5) Al(NO₃)₃ + 3 NaOH → Al(OH)₃ + 3 NaNO₃

(6) Al(OH)₃ → Al₂O₃ + H₂O (nhiệt phân hủy)

Sai sót mong bỏ qua

Answer 2

phương trình (6) quên cân bằng

Answer 3

1/ Cu(OH)2 + H2SO4 ===> CuSO4 + 2H2O

2/ CuSO4 + BaCl2 ===> CuCl2 + BaSO4

3/ CuCl2 +2AgNO3 ===> 2AgCl + Cu(NO3)2

4/ 3Cu(NO3)2 + 2Al ===> 2Al(NO3)3 + 3Cu

5/ Al(NO3)3 +3NaOH ===> Al(OH)3 + 3NaNO3

6/ 2Al(OH)3 ==(nhiệt(==> Al2O3 + 3H2O

Chúc bạn học tốt!!!
