💡 How to Use

Use = or → to separate reactants and products
Separate multiple substances with +
Supports parentheses in formulas, e.g., Ca(OH)₂, Al₂(SO₄)₃
Supports ionic equations with + and - charge notation, e.g., Fe³⁺ as Fe+3
Use standard subscripts: glucose = C6H12O6
Balancing uses linear algebra method for mathematical precision

🔬 Common Reaction Types

Synthesis: A + B → AB (e.g., H₂ + O₂ → H₂O)
Decomposition: AB → A + B (e.g., CaCO₃ → CaO + CO₂)
Single Replacement: A + BC → AC + B (e.g., Fe + CuSO₄ → FeSO₄ + Cu)
Double Replacement: AB + CD → AD + CB (e.g., NaCl + AgNO₃ → AgCl + NaNO₃)
Redox: Electron transfer reactions (e.g., KMnO₄ + HCl)
Acid-Base Neutralization: Acid + Base → Salt + Water (e.g., HCl + NaOH → NaCl + H₂O)
