Question

Cho dãy chất Cu(OH)2, CuCl2, CuS, Cu(NO3)2, Cu,CuO, CuSO4. Viết thành một chuỗi gồm 11 phản ứng hoàn hoàn thành chúng

Answer 1

(1)2Cu + O2=2CuO
(2)CuO+H2O=Cu(OH)2
(3)Cu+S=CuS
(4)CuS+4H2SO4=4H2O+4SO2+CuSO4
(5)CuSO4+2HCl=CuCl2+H2SO4
(6)CuCl2+2AgNO3=Cu(NO3)2+2AgCl
(7)2Cu(NO3)2=2CuO+4NO2+O2
(8)Cu(OH)2=CuO+H2O
(9)2CuSO4=2CuO+2SO2+O2
(10)CuO+2HNO3=Cu(NO3)2+H2O
(11)3Cu+8HNO3=3Cu(NO3)2+4H2O+2NO

Answer 2

(1)2Cu + O2------>2CuO
(2)CuO+H2O------>Cu(OH)2
(3)Cu+S------>CuS
(4)CuS+4H2SO4----->4H2O+4SO2+CuSO4
(5)CuSO4+2HCl----->CuCl2+H2SO4
(6)CuCl2+2AgNO3---->Cu(NO3)2+2AgCl
(7)2Cu(NO3)2------>2CuO+4NO2+O2
(8)Cu(OH)2----->CuO+H2O
(9)2CuSO4----->2CuO+2SO2+O2
(10)CuO+2HNO3----->Cu(NO3)2+H2O
(11)3Cu+8HNO3------->3Cu(NO3)2+4H2O+2NO
