Question

铝，镁，锌，铁，与稀硫酸和稀盐酸反应的化学方程式

Answer 1

锌和稀硫酸Zn + H2SO4 = ZnSO4 + H2↑
铁和稀硫酸Fe + H2SO4 = FeSO4 + H2↑
镁和稀硫酸Mg + H2SO4 = MgSO4 + H2↑
铝和稀硫酸2Al +3H2SO4 = Al2(SO4)3 +3H2↑
锌和稀盐酸Zn + 2HCl === ZnCl2 + H2↑
铁和稀盐酸Fe + 2HCl === FeCl2 + H2↑
镁和稀盐酸Mg+ 2HCl === MgCl2 + H2↑
铝和稀盐酸2Al + 6HCl == 2AlCl3 + 3H2↑

Answer 2

2Al+ 3H2SO4 == Al2(SO4 )3+3 H2 ↑
2Al+ 6HCl == 2 AlCl3+3 H2 ↑
Mg + H2SO4 == MgSO4 + H2 ↑
Mg + 2HCl == MgCl2 + H2 ↑
Zn + H2SO4 == ZnSO4 + H2 ↑
Zn + 2HCl == ZnCl2+ H2 ↑
Fe + H2SO4 == FeSO4 （硫酸亚铁）+ H2 ↑
Fe + 2HCl == FeCl2（氯化亚铁）+ H2 ↑

Answer 3

2Al+6HCl=2AlCl3+3H2↑ 2Al+3H2SO4=Al2（SO4）3+3H2↑
Mg+2HCl=MgCl2+H2↑ Mg+H2SO4=MgSO4+H2↑
Zn+2HCl=ZnCl2+H2↑ Zn+H2SO4=ZnSO4+H2↑
Fe+2HCl=FeCl2+H2↑ Fe+H2SO4=FeSO4+H2↑
