Chemistry (2.1) Chemical Reactions and stoichiometry

Atomic mass

The total mass of one atom of a given element.

Molar mass

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

Molecular mass

A chemical formula of a molecular compound that shows the kinds and number atoms present in a molecule of the product.

Stoichiometry

The determination of the properties in which elements or compounds react with one another.

Law of conservation of mass

In any closed system, the total mass of the system remains constant overtime.

Balanced chemical equation

The number of atoms involved in the reactants side is equal to the number of atoms on the product side.

Quantitative relationship

Relationship between things with respect to their comparative quality, magnate or degree, ratio
