Balance reaction equations while preserving the number of each atom.
Blue: reactant atoms · Amber: product atoms
This browser-based chemistry game helps you balance reaction equations while preserving the number of each atom. Designed for Grades 8–12, it turns an abstract idea into a model you can control, measure, reset, and test without signing up.
Explore Conservation of mass, coefficients, atoms, reactions by changing the available controls and comparing the model’s visual and numerical evidence. Try one variable at a time, then combine changes to test a stronger explanation.
A typical investigation takes 5–10 min. Use it as a lesson demonstration, a guided inquiry activity, a homework experiment, or a quick review. The simulation runs in a modern web browser and does not require an account.
Balance reaction equations while preserving the number of each atom. The main ideas are Conservation of mass, coefficients, atoms, reactions.
Yes. You can run the simulation online for free without creating an account.
Most learners can complete one investigation in 5–10 min. You can repeat it to compare more variables or improve your explanation.
