Question

Hoàn thành PTHH

1. Al + HCl ----> +

2. Fe + H2SO3 ----> +

3. H2 + Fe3O4 ----> +

4. Zn + H2SO4 ----> +

Answer 1

2Al + 6HCl →2AlCl₃ + 3H₂

Fe + H₂SO₃ → FeSO₃ + H₂

4H₂ + Fe₃O₄ ---t^o---> 3Fe + 4H₂O

Zn + H₂SO₄ → ZnSO₄ + H₂

Answer 2

2Al+6HCl--->2AlCl3+3H2

Fe+H2SO3--->FeSO3+H2

2H2+Fe3O4---t*-->3Fe+2H2O

Zn+H2SO4--->ZnSO4+H2

Answer 3

2Al + 6HCl → 2AlCl₃ + 3H₂

Fe + H₂SO₃ →FeSO₃ + H₂

4H₂ + Fe₃O₄ → 4H₂O + 3Fe

Zn + H₂SO₄ →ZnSO₄ + H₂

Answer 4

2Al + 6HCl → 2AlCl₃ + 3H₂

Fe + H₂SO₃ →FeSO₃ + H₂

4H₂ + Fe₃O₄\(\underrightarrow{t^o}\)4H₂O + 3Fe

Zn + H₂SO₄ →ZnSO₄ + H₂
