Year 10Equations
Balancing Chemical Equations
Applying the Law of Conservation of Mass so atom counts match on both sides.
Key Concepts
- Matter cannot be created or destroyed in a chemical reaction.
- Adjust coefficients (big numbers in front), NEVER subscripts.
- Count atoms of each element on Reactant side vs. Product side.
