Решить цепочки: Cu-CuO-CuCl2-Cu(OH)2-CuO-CuSO4 и AlCl3-Al(OH)3-Al2O3-Al2(SO4)3-Al(OH)3

Answer 1

2Cu+O2=2CuO , CuO + 2NaCl=CuCl2 + Na2O , CuCl2 + 2NaOH = Cu(OH)2 , Cu(OH)2 = CuO + H2O , CuO + H2SO4 = CuSO4 + H2O
AlCl3 + 3NaOH = Al(OH)3 + NaCl, 2Al(OH)3 = Al2O3 + 3H2O, Al2O3 + 3H2SO4 = Al2(SO4)3 + 3H2O, Al2(SO4)3 + 6NaOH= 2Al(OH)3 + 3Na2SO4
