At constant temperature, the product of an ideal gas's pressure and volume is always constant.

For an ideal gas at constant pressure, the volume is directly proportional to its temperature.

The volume occupied by an ideal gas is proportional to the number of moles (or molecules) present in the container.

The pressure exerted on the sides of a container by an ideal gas of fixed volume is proportional to its temperature.

The rate at which gas molecules diffuse is inversely proportional to the square root of its density.

At constant temperature, the amount of gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium w/ the liquid

If a chemical system at equilibrium experiences a change in concentration, temperature, volume, or partial pressure, then the equilibrium shifts to counteract the imposed change.

All samples of a given chemical compound have the same elemental composition by mass.

If 2 elements form more than 1 compound between them, the ratios of the masses of the 2nd element combined with a fixed mass of the 1st element will be ratios of wholes #'s

The pressure of a mixture of gases is the sum of the partial pressures of the individual components.

An approximation of the behavior of many gases in many situations. (PV=nRT)

Shows the relationship between the pressure, volume, and temperature for a fixed mass of gas.

The total enthalpy change during the complete course of a reaction is the same whether the reaction is made in one step or in several steps.

The partial vapor pressure of each component of an ideal mixture of liquids is equal to the vapor pressure of the pure component multiplied by its mole fraction in the mixture.

States the classical expression for the molar specific heat capacity of a crystal

Two identical fermions cannot occupy the same quantum state simultaneously.

Electrons fill orbitals starting at the lowest available energy levels before filling higher levels.

Every orbital in a subsehell must have one electron before any orbital can have two.

Any of a variety of mathematical inequalities asserting a fundamental limit to the precision with which certain pairs of physical properties of a particle can be measured.

A thermodynamic potential that measures the 'usefulness' or process-initiating work obtainable from a thermodynamic system at a constant temperature and pressure.

Atoms of main-group elements tend to combine in such a way that each atom has eight electrons in its valence shell.

The reaction rate is proportional to the product of masses of the reacting substances using coefficients as powers

Useful for estimating the pH of a buffer solution and finding the equilibrium pH in acid-base reactions.

Relates the attenuation of light to the properties of the material through which the light is traveling.

Also know as the Madelung, Janet, and Klechowski Rule, it states that orbitals with a lower n + ℓ value are filled before those with higher n + ℓ values.
