Question
Why is the balancing of chemical equation essential?
✓
Answer
- In balanced chemical equation, the number of atoms of each element remains the same on both sides.
- Now, according to the law of conservation of mass, matter can neither be created nor be destroyed in a chemical reaction.
- Hence, the total mass of reactants and products must be equal.
- As a result, it is essential to keep the number of atoms equal in both sides of chemical reaction. Thus, it is the basic need of balancing the chemical equation.
