Question

Hoàn thành các phương trình sau :

a, Fe(OH)₃ \(\rightarrow\) ....... + ........

b, Fe + Cl₂ \(\rightarrow\) ........ + ..........

Answer 1

2Fe(OH)₃ -> Fe₂O₃ + 3H₂O

2Fe + 3Cl₂ -> 2FeCl₃

Answer 2

2Fe(OH)₃ ----t^o--- > Fe₂O₃ + 3H₂O

2Fe + 3Cl₂ ----t^o----> 2FeCl₃

Answer 3

a, 2Fe(OH)₃ → Fe₂O₃ + 3H₂O

b, 2Fe + 3Cl₂ →2FeCl₃

Answer 4

_{\(a.2Fe\left(OH\right)_3\rightarrow Fe_2O_3+3H_2O.\)}

\(b.2Fe\left(OH\right)_3+3Cl_2\rightarrow2FeCl_3\).
