Question 29
Easy

Potassium reacts with chlorine to form potassium chloride.

What is the correctly balanced symbol equation for this reaction?

K+Cl→KCl\text{K} + \text{Cl} \rightarrow \text{KCl}K+Cl→KCl

K+Cl2→KCl2\text{K} + \text{Cl}_2 \rightarrow \text{KCl}_2K+Cl2​→KCl2​

2K+Cl→K2Cl2\text{K} + \text{Cl} \rightarrow \text{K}_2\text{Cl}2K+Cl→K2​Cl

2K+Cl2→2KCl2\text{K} + \text{Cl}_2 \rightarrow 2\text{KCl}2K+Cl2​→2KCl
