💡 3 Pro-Tips to Master Chemical Reactions
1. Master the Physical States: The CBSE board frequently deducts half a mark if you forget to write the physical states (s, l, g, aq) in your final balanced equation. Always double-check this before moving to the next question on your paper.
2. Focus on Color Changes: Board examiners love asking observation-based questions. Make a small sticky note memorizing specific color changes, like the brown fumes of nitrogen dioxide during the heating of lead nitrate, or the exact green shade of ferrous sulfate.
3. The "Hit and Trial" Hack: When balancing equations, always start with the compound that contains the maximum number of atoms, whether it is a reactant or a product. Save balancing hydrogen and oxygen atoms for the very last step to save precious exam time.
