The balancing of chemical equation is based upon:a)Law of conservation...
A chemical equation consists of reactants, products and an arrow showing the direction of reaction. The equation in which number of atoms of all the molecules is equal on both sides of the equation is known as balanced chemical equation. Law of conservation of mass governs the balancing of a chemical equation.

Understanding the Balancing of Chemical Equations
Balancing chemical equations is a fundamental concept in chemistry that ensures the conservation of mass during chemical reactions.
Law of Conservation of Mass
- The law states that matter cannot be created or destroyed in a chemical reaction.
- Therefore, the total mass of reactants must equal the total mass of products.
Importance in Balancing Equations
- When balancing an equation, one must ensure that the number of atoms of each element on the reactant side matches the number on the product side.
- This is done by adjusting coefficients (the numbers placed before compounds) in the equation without changing the chemical formulas.
Example of Balancing
- Consider the reaction of hydrogen and oxygen to form water:
- Unbalanced: H2 + O2 → H2O
- Balanced: 2H2 + O2 → 2H2O
- Here, there are 4 hydrogen atoms and 2 oxygen atoms on both sides.
Conclusion
- Option A, the "Law of Conservation of Mass," is crucial because it underpins the entire process of balancing chemical equations.
- By adhering to this law, chemists can accurately represent chemical reactions and ensure that mass is conserved, which is essential for understanding chemical processes.
Understanding this law not only helps in balancing equations but also lays the groundwork for further studies in chemistry.
