Reaction Balance

Adjust whole-number coefficients while a live atom ledger checks both sides of each reaction.

5–15 min 1 learner

How it works

1. Change coefficients, never formula subscripts. Match every atom count and use the smallest positive whole-number ratio. Symbolic practice only.
2. Read the explanation after each mission. Hints are always available.
3. Choose any mission or resume a local checkpoint. Progress is practice history, not a certified grade.
