Reaction families: name the pattern

Chemists sort reactions by their pattern — and the pattern tells you what to expect. These drills give you a balanced equation and ask which family it belongs to (combustion, synthesis, decomposition, single or double replacement, precipitation, acid-base neutralization, or gas evolution), or which ions are spectators that sit out the reaction. Every equation is balanced and classified by the engine, and the explanations show the evidence — a free element changing hands, an insoluble solid dropping out, an acid meeting a base.
