Potassium iodide (KI) combines with mercury chloride (HgCl2) to form potassium chloride (KCl) and mercury iodide (HgI2) during a
double replacement reaction.
Which of the following shows the balanced chemical equation for this reaction?
2 answers:
<u>Answer:</u> The balanced chemical equation is written below.
<u>Explanation:</u>
Double displacement reaction is defined as the chemical reaction in which exchange of ions takes place.
The chemical equation for the reaction of potassium iodide and mercury (II) chloride follows:
By Stoichiometry of the reaction:
2 moles of potassium iodide reacts with mercury (II) chloride to produce 1 mole of mercury (II) iodide and 2 moles of potassium chloride
Hence, the balanced chemical equation is written above.
2Kl+HgCl2 --> 2KCl + HgI2
