Решите пожалуйста !!! 1)ZnO-Zn-H2-HCl-H2-KH-KOH 2)H2-H2O-O2-CuO-H2O-H2-H2S
1) ZnO + H2 = Zn + H2O Zn + 2HCl = ZnCl2 + H2↑ H2 + 2Cl = 2HCl HCl + Zn = ZnCl + H2↑ 2K + H2 = 2KH KH + H2O = KOH + H2↑ 2) 2H2 + O2 = 2H2O 2H2O = 2H2↑ + O2↑ 2Cu + O2 = 2CuO CuO + H2 = Cu + H2O 2H2O = 2H2↑ + O2↑ H2 + S = H2S↑
