The concentration of a solution expressed as the number of moles of solute per liter of solution.

The reactant in a chemical reaction that is completely consumed first, thus limiting the amount of product that can be formed.

PV = nRT; a relationship between the pressure, volume, temperature, and number of moles of a gas.

A diagram that shows the bonding between atoms of a molecule and lone pairs of electrons that may exist in the molecule.

The number of digits in a measurement that are known with certainty plus one uncertain digit.

The simplest whole-number ratio of atoms in a compound.

Mass per unit volume

Sets of numbers describing the properties of atomic orbitals and the electrons in them.

A systematic process of observation, experimentation, and analysis used to gain knowledge and understanding of the natural world.

Precision refers to the closeness of measurements to each other, while accuracy refers to the closeness of measurements to the true value.

Physical changes alter a substance's appearance but not its chemical composition, while chemical changes involve the formation of new substances with different properties.

A molecule is formed when two or more atoms bond together, while an ion is an atom or group of atoms that has gained or lost electrons, resulting in a net electrical charge.

A symbolic representation of a chemical reaction, showing the chemical formulas of reactants and products, and their stoichiometric coefficients.

Reactions are categorized based on their characteristics. Types include acid-base, redox, and precipitation reactions.

A model that describes the behavior of gases under ideal conditions, relating pressure (P), volume (V), temperature (T), and number of moles (n) with the ideal gas constant (R): PV = nRT.

The wavelength associated with a moving particle, demonstrating wave-particle duality, calculated by λ = h/mv, where h is Planck's constant, m is mass, and v is velocity.
