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

Answer 2

It looks like you've listed various chemical compounds containing iron (Fe) with different combinations of elements. Here's the breakdown of each compound:

1. Fe: This is just the chemical symbol for iron, representing the element itself.

2. FeCl2: Iron(II) chloride, also known as ferrous chloride. It consists of one iron (Fe) atom and two chlorine (Cl) atoms.

3. FeCl3: Iron(III) chloride, also known as ferric chloride. It contains one iron (Fe) atom and three chlorine (Cl) atoms.

4. Fe(NO3)2: Iron(II) nitrate, also called ferrous nitrate. It comprises one iron (Fe) atom and two nitrate (NO3) groups.

5. Fe(OH)3: Iron(III) hydroxide, also known as ferric hydroxide. It consists of one iron (Fe) atom and three hydroxide (OH) groups.

6. Fe2O3: Iron(III) oxide, commonly known as ferric oxide or rust. It contains two iron (Fe) atoms and three oxygen (O) atoms.
