Question

Fe-FeCI2-Fe(NO3)4-Fe(OH)2-FeO-Fe

Answer 1

Fe + 2HCl = FeCl2 + H2

FeCl2 + 2AgNO3 = Fe(NO3)2 + 2AgCl

Fe(NO3)2 + Ba(OH)2 = Ba(NO3)2 + Fe(OH)2

Fe(OH)2 (t)= FeO + H2O

FeO + C (t)= Fe + CO

Answer 2

The given sequence appears to be a list of chemical compounds involving iron (Fe). Here's how each compound is named and a brief description of each:

1. Fe: This simply represents elemental iron, which is a pure metal consisting of iron atoms.

2. FeCl2: This is iron(II) chloride, also known as ferrous chloride. It is a compound containing one iron (Fe) atom and two chloride (Cl) ions.

3. Fe(NO3)4: This is iron(III) nitrate, also known as ferric nitrate. It is a compound containing one iron (Fe) atom and four nitrate (NO3) ions.

4. Fe(OH)2: This is iron(II) hydroxide, also known as ferrous hydroxide. It is a compound containing one iron (Fe) atom and two hydroxide (OH) ions.

5. FeO: This is iron(II) oxide, also known as ferrous oxide or iron monoxide. It is a compound containing one iron (Fe) atom and one oxygen (O) atom.

The sequence appears to be listing different iron compounds with varying oxidation states and anions. If you have any specific questions about these compounds or their properties, feel free to ask!
