What is the balanced equation of iron (iii) hydrogen carbonate?

Lynna [10]

<h3>Answer:</h3>

2Fe(HCO₃)₃ → Fe₂(CO₃)₃ + 3H₂O + 3CO₂

<h3>Explanation:</h3>

A decomposition reaction is one in which a large compound is broken down into smaller compounds or individual elements.
The decomposition reaction Iron (iii) hydrogen carbonate yield iron (iii) carbonate, water and carbon dioxide.

Fe(HCO₃)₃ → Fe₂(CO₃)₃ + H₂O + CO₂

A balanced equation is the one in which the number of atoms of each element are equal on both side of the equation.

Therefore; the balanced equation for the decomposition of Iron (iii) hydrogen carbonate is given by;

2Fe(HCO₃)₃ → Fe₂(CO₃)₃ + 3H₂O + 3CO₂

Write the NET IONIC EQUATION between iron and copper (II) sulfate.

ratelena [41]

<u>Answer:</u> The net ionic equation is written below.

<u>Explanation:</u>

Net ionic equation of any reaction does not include any spectator ions.

Spectator ions are defined as the ions which does not get involved in a chemical equation. They are found on both the sides of the chemical reaction when it is present in ionic form.

The chemical equation for the reaction of iron and copper (II) sulfate is given as:

$Fe(s)+CuSO_4(aq.)\rightarrow FeSO_4(aq.)+Cu(s)$

Ionic form of the above equation follows:

$Fe(s)+Cu^{2+}(aq.)+SO_4^{2-}(aq.)\rightarrow Fe^{2+}(aq.)+SO_4^{2-}(aq.)+Cu(s)$

As, sulfate ions are present on both the sides of the reaction. Thus, it will not be present in the net ionic equation and are spectator ions.

The net ionic equation for the above reaction follows:

$Fe(s)+Cu^{2+}(aq.)\rightarrow Fe^{2+}(aq.)+Cu(s)$

Hence, the net ionic equation is written above.
