What name is given to the reagent that is completely used up during a chemical reaction?

1. When substances are mixed, one of them usually runs out before the others do. 2. A reagent that is completely used up in the reaction is the limiting reagent. 3. Once it is gone the reaction stops, however much of the other substances remains. 4. The reagent that is not completely used up is called the excess reagent. _Source: Siyavula Physical Sciences Grade 11 (Everything Science, CC BY 4.0), Chapter 8: Quantitative aspects of chemical change_
