Question

Fe Fecl_2 Fecl_3 Fe(NO_3)_2 Fe(OH)_3 Fe_2O_3 Fe

Answer 1

Ответ:

Fe→ FeCI₂→ Fe(NO₃)₂

↓

→ FeCI₃→ Fe(OH)₃ →Fe₂O₃→ Fe

Fe+HCI= FeCI₂+H₂↑

FeCI₂+2AgNO₃= Fe(NO₃)₂+2AgCI↓

Fe→FeCI₃→ Fe(OH)₃ →Fe₂O₃→ Fe

2Fe+3CI₂=2FeCI₃

FeCI₃+3NaOH= Fe(OH)₃↓+3NaCI

2Fe(OH)₃+t°C =Fe₂O₃+3H₂O

Fe₂O₃+2AI= 2Fe+AI₂O₃
