Question

Помогите составить уравнения реакций! CU---CuO---CuCl2---Cu(OH)2---CUO---CU---CuSO4---Cu(OH)2

Answer 1

2Cu + O2 = 2CuO
CuO + 2HCl = CuCl2 + H2O
CuCl2 + 2 NaOH = Cu(OH)2 + 2NaCl
Cu(OH)2 = CuO + H2O
CuO + C = Cu + CO
Cu + 2H2SO4(конц) = CuSO4 + SO2 + 2H2O
CuSO4 + 2NaOH = Cu(OH)2 + Na2SO4

Answer 2

$2Cu+O_{2}=2CuO$
$CuO+2HCl=CuCl _{2}+H_{2}O$
$CuCl _{2}+2NaOH=Cu(OH) _{2} +NaCl$
$Cu(OH) _{2}=CuO+H_{2}O$
$3CuO+2Al=3Cu+Al_{2}O_{3}$
$Cu+2H _{2}SO_{4}=CuSO_{4}+SO_{2}+H_{2}O$
$CuSO_{4}+2NaOH=Cu(OH)_{2}+Na_{2}SO_{4}$
