Stoichiometry

These flashcards cover key vocabulary terms related to stoichiometry, chemical reactions, and their mathematical principles.

Stoichiometry

The relationship between various amounts of reactants and/or products in a chemical equation.

Law of Conservation of Mass

The law stating that during a chemical reaction, the total mass of reactants must equal the total mass of products.

Coefficients

Numbers placed in front of reactants and products in a chemical equation to indicate the number of moles of each.

Balanced Chemical Equation

An equation where the number of atoms for each element is the same on both sides.

Limiting Reactant

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

Excess Reactant

The reactant that remains after the limiting reactant is completely consumed.

Empirical Formula

The simplest whole number ratio of the elements in a compound.

Molar Mass

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

Mole-to-Mole Conversions

Calculations that relate the quantities of reactants and products using their coefficients from a balanced chemical equation.

Percent Yield

A measure of the efficiency of a chemical reaction, calculated as (actual yield/theoretical yield) x 100.
