About Chemical Equation Balancing
Chemical equation balancing ensures that the number of atoms of each element is the same on both sides of the equation, following the law of conservation of mass.
Balancing Rules:
- Never change subscripts in formulas
- Only change coefficients (numbers in front)
- Start with elements that appear in only one compound
- Balance polyatomic ions as units
- Check your work by counting atoms
Equation Format:
- Use + to separate reactants/products
- Use = to separate reactants from products
- Use proper chemical formulas
- Include state symbols if needed
- Example: H2 + O2 = H2O
