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↑
