A three-mode educational chemistry simulator: mix any of the 118 elements and 50+ common compounds in an animated reactor vessel. Beginner mode tells the story of each reaction; Advanced adds real stoichiometry with limiting reagents and yields; Scientist unlocks ΔH energies, redox half-equations and reaction conditions. Built on a database of 150+ verified, balanced reactions — with honest labels when a combination is predicted or simply doesn't react.

Click any element to see its atomic mass, group and properties.
