Lecture 20 – Limiting Reagents, Percent Yield

These flashcards cover key vocabulary related to limiting reagents and percent yield, essential for understanding chemical reactions.

Limiting Reagent

The reactant that runs out first in a chemical reaction.

Theoretical Yield

The amount of product formed assuming complete reaction of the limiting reagent.

Actual Yield

The amount of product actually formed in a chemical reaction.

Percent Yield

The percent of the theoretical yield that is actually obtained from a chemical reaction.

Mole Ratio

The ratio between the amounts in moles of any two compounds involved in a chemical reaction.

Excess Reactant

The reactant that is not completely consumed in a chemical reaction.

Complete Reaction

When all of the limiting reagent is consumed in a chemical reaction.

Mass-to-Mole Conversion

The process of converting mass of a substance to moles using its molar mass.
