About this app
Balancing Chemical Equations is an interactive middle-school chemistry learning app focused on molecules, coefficients, and conservation of atoms. Learners build molecules by selecting atoms, balance chemical equations by adjusting coefficients, and explore how hydrogen and oxygen combine into water with different leftover materials.
Use cases
- Middle-school students learning chemical formulas
- Teachers introducing conservation of mass
- Practice with molecular subscripts and coefficients
- Classroom review of common chemical reactions
Features
- Builds water, carbon dioxide, methane, and ammonia from selectable atoms
- Explains how subscripts represent the number of atoms in a molecule
- Balances equations for water, ammonia, methane combustion, and iron rusting
- Displays before-and-after element counts while balancing
- Models water formation using a 2:1 hydrogen-to-oxygen molecule ratio
- Includes reset and next-activity controls
