Question

Write and balance the following single
replacement reaction.
i) Cl₂ + KI →

Answer 1

2KI+Cl2—>2KCl+I2

Step-by-step explanation:

This is a displacementreaction in which the less reactive iodine in potassium iodide is displaced by more reactive chlorine.

Answer 2

The balanced chemical equation for the single replacement reaction between chlorine gas (Cl2) and potassium iodide (KI) is:

Cl2+ 2KI → 2KCl + I2

Step-by-step explanation:

The balanced chemical equation for the single replacement reaction between chlorine gas (Cl2) and potassium iodide (KI) is:

Cl2 + 2KI → 2KCl + I2

In this reaction, the chlorine gas reacts with the potassium iodide to form potassium chloride and iodine. The chlorine gas replaces the iodine in the potassium iodide compound, resulting in the formation of potassium chloride and iodine. The equation is balanced because there are equal numbers of atoms of each element on both sides of the arrow.
