Chemistry Review: Moles, Stoichiometry, and Balancing Equations

These flashcards cover essential vocabulary related to chemistry concepts including moles, stoichiometry, balancing equations, and related calculations.

Chemical Equations

Represent chemical reactions on paper showing reactants and products.

Law of Conservation of Mass

Mass is neither created nor destroyed in a chemical reaction.

Balanced Chemical Equation

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

The Mole

A standard measurement in chemistry representing 6.022 x 10²³ entities.

Avogadro's Number (NA)

The number of particles in one mole, approximately 6.022 x 10²³.

Mole Ratio

The ratio of moles of one substance to moles of another in a balanced equation.

Limiting Reactant

The reactant that is consumed first, limiting the amount of product formed.

Percent Yield

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

Molecular Weight

The sum of the atomic weights of all atoms in a molecule.

Molar Mass

The mass of one mole of a substance, expressed in grams per mole (g/mol).
