Question

Fe-➡️FeCl2➡️Fe(oh)2➡️FeCo3➡️Fe3(po)2

Answer 1

Fe +2HCl->FeCl2+H2
FeCl2+2NaOH->2NaCl+Fe(OH)2
Fe(OH)2+Na2CO3->2Na(OH)+FeCO3
3FeCO3+2K3PO4->Fe3(PO4)2+3K2CO3

Answer 2

The sequence you provided seems to represent a series of chemical reactions involving iron (Fe) and various compounds. However, there are a few issues with the representation you've given. Chemical reactions typically involve reactants and products, and the reactants on the left side of the arrow should convert into the products on the right side of the arrow.

Assuming you meant to represent a series of reactions, I'll correct the equations for you and provide some additional information about each reaction:

1. Fe → FeCl2 This equation represents the reaction between iron (Fe) and chlorine (Cl2) gas, resulting in the formation of iron(II) chloride (FeCl2). The balanced equation for this reaction is: 2 Fe + Cl2 → 2 FeCl2

2. FeCl2 → Fe(OH)2 In this reaction, iron(II) chloride (FeCl2) reacts with a base to form iron(II) hydroxide (Fe(OH)2). The balanced equation for this reaction is: FeCl2 + 2 NaOH → Fe(OH)2 + 2 NaCl

3. Fe(OH)2 → FeCO3 This equation represents the reaction where iron(II) hydroxide (Fe(OH)2) undergoes a chemical change and transforms into iron(II) carbonate (FeCO3). The balanced equation for this reaction is: Fe(OH)2 + CO2 → FeCO3 + H2O

4. FeCO3 → Fe3(PO4)2 This equation shows the reaction between iron(II) carbonate (FeCO3) and phosphoric acid (H3PO4), resulting in the formation of iron(III) phosphate (Fe3(PO4)2). The balanced equation for this reaction is: 3 FeCO3 + 2 H3PO4 → Fe3(PO4)2 + 3 CO2 + 3 H2O

It's important to note that the stoichiometry and conditions (such as temperature and pressure) of these reactions can vary, and additional information would be required to provide more specific details.
