Stoichiometry and Yield topic test

Use one compact chemistry branch where a visible recipe bench connects stoichiometric ratios, limiting reagent, and percent yield without leaving the same particle-and-recipe language.

What this run covers

This first-pass topic test reuses the shared quiz engine, but it balances question selection across the included concepts so the topic is assessed as a broader branch instead of a single concept replay.

Every topic test still points back to the published topic page and the included concept pages, so you can review the exact learning surfaces behind the questions.

Chemistry

Stoichiometric Ratios and Recipe Batches

Keep one reaction recipe visible so stoichiometric ratios read as complete batches, not detached worksheet proportions.

Chemistry

Limiting Reagent and Leftover Reactants

Use one recipe bench to see which reactant caps the output first and why the other reactant can remain in excess.

Chemistry

Percent Yield and Reaction Extent

Compare actual output with the same theoretical recipe cap so percent yield stays visual and honest on one shared bench.
