Stoichiometry & Balancing Chemical Equations

Integrated Sciences (Biology, Chemistry, Physics)

Your child applies the Law of Conservation of Mass to balance basic chemical equations on paper, ensuring that the number of reactant atoms matches the product atoms.

In real life

Noticing moisture above a gas hob, your child asks where the water came from. They balance CH₄ + 2O₂ → CO₂ + 2H₂O on paper and explain that burning methane makes water vapour as well as carbon dioxide and heat.
