制取氢气的化学方程式

Question

如题所述

Answer 1

实验室制取氢气
Zn+H2SO4=H2↑+ZnSO4
2Al + 6HCl = 2 AlCl3 + 3 H2↑
2Al + 2NaOH + 2H2O = 2NaAlO2 + 3H2↑
Fe+2HCl=FeCl2+H2↑
Mg+ 2HCl === MgCl2 + H2↑
2Al +3H2SO4 = Al2(SO4)3 +3H2↑
Zn + 2HCl === ZnCl2 + H2↑
Fe + H2SO4 = FeSO4 + H2↑
Mg + H2SO4 = MgSO4 + H2↑

Answer 2

实验室制取氢气
Zn+H2SO4=H2↑+ZnSO4
2Al + 6HCl = 2 AlCl3 + 3 H2↑
2Al + 2NaOH + 2H2O = 2NaAlO2 + 3H2↑
Fe+2HCl=FeCl2+H2↑
Mg+ 2HCl === MgCl2 + H2↑
2Al +3H2SO4 = Al2(SO4)3 +3H2↑
Zn + 2HCl === ZnCl2 + H2↑
Fe + H2SO4 = FeSO4 + H2↑
Mg + H2SO4 = MgSO4 + H2↑

可燃性
2H2 + O2= 点燃= 2H2O

还原性
H2 + CuO =加热= Cu + H2O

Answer 3

制取氢气有很多方法，利用活泼金属与酸反应

Zn＋H2SO4=H2+ZnSO4

或者电解水: 2H2O == 2H2 + O2

Answer 4

锌和稀硫酸反应制氢气：Zn+H2SO4=ZnSO4+H2↑

Answer 5

Zn+2Hcl=Zncl2+H2(气体)
