Stoichiometry and Chemical Reactions

These flashcards cover key concepts, definitions, and calculations related to stoichiometry, chemical reactions, and yields.

Stoichiometry

The process of using a balanced chemical equation to calculate the relative masses of reactants and products involved in a reaction.

Mole Ratios

Ratios derived from the coefficients of a balanced chemical equation, used to determine the proportions of reactants and products.

Limiting Reactant

The reactant that is completely consumed in a reaction, thus determining the maximum amount of products formed.

Theoretical Yield

The maximum amount of product that can be generated from given amounts of reactants.

Actual Yield

The measured amount of a product obtained from a reaction.

Percent Yield

A calculation that compares the actual yield of a reaction to its theoretical yield, expressed as a percentage.

Balanced Equation

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

Molar Mass

The mass of one mole of a substance, calculated using the atomic masses from the periodic table.

Avogadro's Number

The number of particles in one mole of a substance, approximately 6.022 x 10^23.

Conversion Factors in Stoichiometry

Ratios used for converting between moles, grams, and particles in chemical calculations.
