Question

решить цепочку.Cu-CuO-CuCl2-Cu(OH)2-CuO-CuSO4

Answer 1

2Cu+O2=2CuO    Cuo+2HCl=CuCl2++H2O CuCl2 +2NaOH=Cu(OH)2+2NaCl
Cu(OH)2= CuO+H2O
CuO+H2SO4= CuSO4+H2O

Answer 2

2Cu + O2 = 2CuO
CuO + 2HCl = CuCl2 + H2O
CuCl2 + 2KOH = Cu(OH)2 + 2KCl
Cu(OH)2 ---t-- > CuO + H2O
CuO + H2SO4 = CuSO$ + H2O
