Limiting Reagents and Excess Reagents

These flashcards cover key concepts related to limiting and excess reagents, balancing chemical equations, and stoichiometric calculations.

Limiting Reagent

The reactant that determines the amount of product that can be formed in a chemical reaction, as it will be consumed first.

Excess Reagent

The reactant that remains after the limiting reagent has been completely consumed in a chemical reaction.

Chemical Equation

A mathematical representation of a chemical reaction, showing the reactants and products along with their relative amounts.

Balanced Equation

An equation in which the number of atoms for each element is equal on both sides of the reaction.

Chemical Yield

The amount of product obtained from a chemical reaction, typically expressed as a percentage of the theoretical yield.

Molar Mass

The mass of one mole of a substance, typically expressed in grams per mole (g/mol), used to convert between grams and moles.

Stoichiometry

The calculation of reactants and products in chemical reactions based on the balanced equation.

Conversion Factor

A ratio used to convert from one unit to another, which in chemistry often includes units of mass to moles.

Cycle Through

The process of repeatedly using reactants in a reaction until one or more is completely consumed.

Product

The substances formed as a result of a chemical reaction.
