Law of Conservation of Mass: Atoms are neither created nor destroyed. The number of atoms of each element must be equal on both sides.
Example: Fe + O₂ → Fe₂O₃
- Unbalanced: Fe=1 (left), Fe=2 (right) — not equal
- Balanced: 4Fe + 3O₂ → 2Fe₂O₃
- Check: Fe = 4 on both sides, O = 6 on both sides ✓
Tip: Separate compounds with + signs. Use standard chemical notation (e.g., H2O, CO2, Fe2O3).
Frequently Asked Questions
Why do we need to balance chemical equations?
Chemical equations must be balanced to obey the Law of Conservation of Mass — atoms are neither created nor destroyed in a chemical reaction. The number of atoms of each element must be the same on both sides of the equation.
How do you balance a chemical equation step by step?
Step 1: Write the unbalanced equation. Step 2: List all elements on both sides. Step 3: Start balancing elements that appear in only one reactant and product. Step 4: Balance hydrogen and oxygen last. Step 5: Verify all atoms are equal on both sides. Step 6: Ensure coefficients are in the smallest whole-number ratio.
What are the common types of chemical reactions for board exams?
The five main types are: Combination (A + B → AB), Decomposition (AB → A + B), Displacement (A + BC → AC + B), Double displacement (AB + CD → AD + CB), and Redox (involves transfer of electrons). CBSE Class 10 Chapter 1 covers all these types.
How is this tool useful for JEE and NEET?
For JEE and NEET, balancing equations is essential in stoichiometry, electrochemistry, and organic chemistry. This tool helps you verify your manual balancing and understand the correct coefficients for mole calculations.
