Quick Reference: Balancing Rules

Rule	Explanation
Only change coefficients	Numbers in FRONT of formulas (e.g., 2H₂O)
Never change subscripts	Numbers BELOW change the substance (H₂O ≠ H₂O₂)
Balance one element at a time	Start with metals, end with O and H
Count ALL atoms	Coefficient × subscript = total atoms
