Question

hoan thanh phan ung hoa hoc sau:

? Mg+ ? ------> 2MgO

? Al+ ?------>HCl+ ? AlCl3+?H2

Fe2O3+?HCl------->?FeCl3+?H2O

?Fe(OH)3+H2(SO4)----->Fe2(SO4)3+?H2O

Answer 1

ai tra loi giup minh voi

 

Answer 2

+ 2Mg + O₂ → 2MgO

+ 2Al + 6HCl → 2AlCl₃ + 3H₂\(\uparrow\)

+ Fe₂O₃ + 6HCl → 2FeCl₃ + 3H₂O

+ 2Fe(OH)₃ + 3H₂SO4 → Fe₂(SO₄)₃ + 6H₂O

Answer 3

2Mg + O₂ ===> 2MgO2Al + 6HCl ===> 2AlCl₃ + 3H₂Fe₂O₃ + 6HCl ===> 2FeCl₃ + 3H₂O2Fe(OH)₃ + 3H₂SO₄ ===> Fe₂(SO₄)₃ + 6H₂O

Answer 4

2Mg + O₂ -> 2MgO

2Al+ 6HCl -> 2AlCl₃+ 3H₂

Fe₂O₃ + 6HCl ->2FeCl₃ +3H₂O

2Fe( OH)₃ +3H₂( SO₄) -> Fe₂( SO₄)₃ + 6H₂O

tick cho mk nhá :)

Answer 5

2Mg + O₂ -> 2MgO

2 Al+ 6HCl -> 2AlCl₃+3H₂

Fe₂O₃+6HCl------->2FeCl₃+3H₂O

2Fe(OH)₃+3H₂(SO₄)----->Fe₂(SO₄)₃+6H₂O
