Limiting Reagent & Yield
Balance a reaction, then find which reactant runs out first and what it can theoretically produce.
Reaction
Unbalanced is fine — any coefficients you type are ignored. Separate species with
+ and the sides with ->.

A row appears here for each reactant once the equation balances.

What you isolated, dry. Leave blank for the theoretical figures alone.
Balanced equation
—
A reaction fails to balance for one of three reasons, and the message above says which: an element that appears on only one side, no balance at all, or more than one independent balance — which means two reactions written as one, and they have to be split.
