Atom Economy — Chemistry Interactive Simulation
An interactive ClassAdapt simulation teaching atom economy (also searched as “atom efficiency”) for Chemistry. Pupils select from six real reactions and watch the relative formula mass (Mᵣ) of products split into a colour-coded bar — green for the wanted product, red for the waste by-product — with a live atom economy percentage gauge.
Key search phrases / topics covered:
- Atom economy calculation GCSE
- Atom economy formula: (Mᵣ of wanted product ÷ total Mᵣ of all products) × 100
- Percentage atom economy
- Relative formula mass (Mᵣ) / Mr calculation
- Balanced symbol equations
- Wanted product vs waste product / by-product
- Green chemistry / sustainable chemistry / reducing waste
- Industrial reactions and reaction economics
Reactions modelled (with searchable contexts):
- Hydration of ethene → ethanol (100% atom economy, addition reaction example)
- Thermal decomposition of limestone (calcium carbonate → calcium oxide)
- Thermite reaction / extraction of iron with aluminium
- Fermentation of glucose → ethanol
- Electrolysis of water → hydrogen
- Zinc + sulfuric acid → hydrogen (low atom economy example)
