Stoichiometry

These flashcards cover key concepts in stoichiometry, including definitions and important terms related to chemical reactions.

Stoichiometry

The calculation of reactants and products in chemical reactions.

Limiting Reagent

The reactant that is completely consumed in a chemical reaction, limiting the amount of product formed.

Percent Yield

The ratio of actual yield to theoretical yield expressed as a percentage.

Mole

A unit of measurement in chemistry that represents 6.022 x 10^23 molecules.

Theoretical Yield

The maximum amount of product that could be formed from given amounts of reactants.

Actual Yield

The amount of product actually obtained from a reaction in the laboratory.

Stoichiometric Conversion Factor

A ratio derived from the coefficients of a balanced chemical equation that is used to convert between moles of reactants and products.

Balanced Equation

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

Molar Mass

The mass of one mole of a substance, usually expressed in grams per mole.

Excess Reactant

The reactant that remains after a chemical reaction is complete.

Chemical Reaction

A process that leads to the transformation of one set of chemical substances to another.

Reactants

The starting materials in a chemical reaction.

Products

The substances formed as a result of a chemical reaction.

Stoichiometric Ratio

The ratio of moles of reactants to moles of products in a balanced chemical equation.

Conversion between compounds

The process of using stoichiometry to calculate amounts of different substances involved in a reaction.
