Two modes. Draw: build the structure atom-by-atom on a canvas and get graded. Pick: identify the correct formula for a rendered structure. Covers molecules, ions, oxoacids, and more.
Four modes of stoichiometry drill. Balance equations, classify reaction types, pick the limiting reagent, or race the clock on molar masses. 80-question pool across difficulties.
