Steps or process of balancing equations like barium chloride+potassium sulphate-->barium sulphate+potassium chloride.Explain.
Step 1: To write the chemical reaction into chemical equation.
BaCl2+K2SO4⟶BaSO4+KCl
Step 2: The total number of atoms of each element on the reactant side and the product side must be compared.
Elements Reactant side Product side Ba 1 1 Cl 2 1 K 2 1 S 1 1 O 4 4
Cl and K atoms are not same on both sides.
Step: 3 Now, stoichiometric coefficients are added to molecules containing an element which has a different number of atoms in the reactant side and the product side.
The coefficient must balance the number of atoms on each side.
Add coefficient 2 in front of KCl, then equation becomes
BaCl2+K2SO4⟶BaSO4+2KCl
Every element now has an equal number of atoms in the reactant and product side.Hence the reaction is balanced.

| Elements | Reactant side | Product side |
| Ba | 1 | 1 |
| Cl | 2 | 1 |
