Potassium metal and chloride gas combine to form potassium chloride

The chemical equation for the reaction can be represented as follows:

2 K (s) + Cl2 (g) → 2 KCl (s)

In this reaction, solid potassium metal (K) reacts with gaseous chlorine (Cl2) to produce solid potassium chloride (KCl). The reaction is exothermic, meaning it releases heat.
