Question

Закончите уравнения реакций:

Молекулярное уравнение                                             Сокращено ионное уравнение

1)__FeO+__HCl-->                                                             1)

2)__Fe2O3+__HCl-->                                                         2)

3)__Fe(OH)2+__HCl-->                                                      3)

4)__Fe(OH)3+__HCl-->                                                      4)

Answer 1

 1) FeO + 2HCl = FeCl₂ + H₂O

FeO + 2H⁺ + 2Cl⁻ = Fe²⁺ + 2Cl⁻ + H₂O

FeO + 2H⁺ = Fe²⁺ + H₂O

 

 

2)Fe₂O₃ + 6HCl= 2FeCl₃ + 3H₂O

Fe₂O₃ + 6H⁺ + 6Cl⁻ = 2Fe³⁺ + 6Cl⁻ + 3H₂O

Fe₂O₃ + 6H⁺ = Fe³⁺ + 3H₂O
