Viết PTHH cho những chuyển đổi hh. CuO---->CuSO4--->Cu(NO3)2--->Cu(OH)2---->CuO--->CuCl2--->Cu (mọi ng giúp e với ạ)

Câu 4: Viết PTHH thực hiện chuỗi biến hóa sau:
Cu(OH)2 ->CuO -> CuSO4 ->CuCl2 ->Cu(NO3)2 -> Cu -> CuO.
$Cu(OH)_2 \xrightarrow{t^o} CuO + H_2O$
$CuO + H_2SO_4 \to CuSO_4 + H_2O$
$CuSO_4 + BaCl_2 \to BaSO_4 + CuCl_2$
$CuCl_2 + 2AgNO_3 \to 2AgCl + Cu(NO_3)_2$
$Cu(NO_3)_2 + Fe \to Cu + Fe(NO_3)_2$
$2Cu + O_2 \xrightarrow{t^o} 2CuO$
