a limiting reactant
Explanation: the limiting reactant (or limiting reagent) is the substance that is completely consumed first, stopping the reaction and determining how much product can form. (A "reactant" is any starting substance; "product" is formed, not run out; "limiting product" is not a standard term.)
Example: 2 H2 + O2 → 2 H2O. If you have 3 mol H2 and 1 mol O2, O2 is the limiting reactant (it will be used up first), leaving 1 mol H2 unreacted.
