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
