Unit 7B Classification of Chemical Reactions: Mole and Mass Relationships

These flashcards cover key vocabulary and concepts related to the mole and mass relationships in chemical reactions, as discussed in the lecture notes.

Mole

A counting unit in chemistry used to quantify a specific number of particles, such as atoms, ions, or molecules.

Avogadro’s Number

The number of particles in one mole of a substance, equal to 6.02 imes 10^{23}.

Molar Mass

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

Theoretical Yield

The maximum amount of product that can be produced in a chemical reaction based on the balanced equation.

Percent Yield

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

Balanced Chemical Equation

An equation that shows the equal number of each type of atom on both sides and reflects the conservation of mass.

Mole Ratio

A ratio of the coefficients of any two substances in a balanced chemical equation.

Unit Conversion

A mathematical process used to convert a quantity from one unit to another.

Actual Yield

The amount of product that is actually obtained from a chemical reaction.

Conservation of Mass

The principle stating that mass cannot be created or destroyed in a chemical reaction; the mass of reactants equals the mass of products.
