Understanding Chemical Equations

A balanced chemical equation has equal numbers of each type of atom on both sides, following the Law of Conservation of Mass. Common reaction types include:

• Combustion - CH4 + O2 → CO2 + H2O
• Synthesis - N2 + H2 → NH3
• Decomposition - H2O → H2 + O2
• Single Replacement - Fe + O2 → Fe2O3

Common Use Cases

• Class 10-12 chemistry homework
• CBSE, ICSE chemistry exam preparation
• JEE Main and Advanced chemistry practice
• NEET chemistry preparation
• Stoichiometry calculations
• Chemical reaction understanding

Tips for Balancing Equations

• Always write correct chemical formulas first
• Balance one element at a time
• Save polyatomic ions for last
• Use the smallest whole number coefficients
• Verify that all atoms are balanced
• Never change subscripts, only coefficients
