(1) 2Cu + O2 ---> 2CuO
(2) CuO + H2SO4 ---> CuSO4 + H2
(3) CuSO4 + 2NaOH ---> Cu(OH)2 + Na2SO4
(4) Cu(OH)2 + 2HCl ---> CuCl2 + 2H2O
(5) CuCl2 + 2AgNO3 ----> Cu(NO3)2 + 2AgCl
\(2Cu+O_2\underrightarrow{t^o}2CuO\)
\(CuO+2HCl->CuCl_2+H_2O\)
\(CuCl_2+2NaOH->Cu\left(OH\right)_2\downarrow+2NaCl\)
\(Cu\left(OH\right)_2+H_2SO_4->CuSO_4+2H_2O\)
\(CuSO_4+Ba\left(NO_3\right)_2->Cu\left(NO_3\right)_2+BaSO_4\downarrow\)
2Cu + O2 ---> 2CuO
CuO + HCl ---> CuCl2 + H2O
CuCl2 + Ba(OH)2 ---> Cu(OH)2 + BaCl2
Cu(OH)2 ---to--> CuO + H2O
CuO + SO3 ---> CuSO4
CuSO4 + Pb(NO3)2 --->Cu(NO3)2 + PbSO4
