let us write a chemical equation; word equation is Potassium metal + Chlorine Gas --------> Potassium Chloride The chemical equation using symbols and formula is K (s) + C l 2 (g) ---------> 2KCl (s) the two reactants are Potassium and Chlorine gas , and the product is Potassium Chloride. K (s) + C l 2 (g) ---------> 2KCl (s) reactant side K = 1 product side K=2 Cl = 2 Cl =2 the number of Cl atoms on both the sides are equal, in order to balance the number of K atoms on both the sides, we add one K on the reactant side. 2K (s) + C l 2 (g) ---------> 2KCl (s) reactant side K = 1 + 1= 2 product side K=2 Cl = 2 Cl =2 the equation is now balanced. I’m very sorry if it’s wrong I tried my best
