How can I balance this chemical equations? Potassium metal and chlorine gas combine to form potassium chloride.
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) + ##Cl_2## (g) ---------> 2KCl (s)
the two reactants are Potassium and Chlorine gas , and the product is Potassium Chloride.
K (s) + ##Cl_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) + ##Cl_2## (g) ---------> 2KCl (s)
reactant side K = 1 + 1= 2 product side K=2 Cl = 2 Cl =2
the equation is now balanced.
