About this Simulation

This interactive simulation allows learners to explore chemical equations by adjusting the coefficients of reactants and products. Students can experiment with different molecular combinations, observe how equations must satisfy conservation of mass, and develop intuition for balancing chemical reactions in a risk-free, visual environment.

Learning objectives: Understand the principle of mass conservation in chemical reactions | Apply coefficient rules to balance equations with multiple reactants and products | Recognise the relationship between reactant and product quantities in stoichiometry
