Question | Answer |
---|---|
Pauli Exclusion Principle: | an atomic orbital may describe at most two electrons, each with opposite spin directions. |
Henry's Law: | at a given temperature the solubility of a gas in a liquid is directlt proportional to the pressure of the gas above the liquid. |
Heisenberg Uncertainty Principle: | it is impossible to know exactly both the volocity and the position of a particle at the same time. |
Hund's rule: | electrons occupy orbitals of the same energy in a way that makes the number of elecrons with the same spin direction as large as possible. |
Aufbau principle: | the rule that elecrons occupy the orbitals of lowest energy first. |
Boyle's Law: | for a given mass of gas at constant temperature, the volume of gas varies intervesely with pressure. |
Le Châtelier's Principle: | If stress is applied to a system in dynamic equilibrium, the system changes in a way that relieves the stress, dude! |
Dalton's law: | at constant volume and temperature, the total pressure exerted by a mixture of gasses is equal to the sum of the partial pressures of the component gases. |
Ideal gas law: | P x V= n x R x T or PV=nRT |
Gay-Lussacs Law: | a pressure of a gas is directly proportional to the Kelvin temperature if the volume remains constant. |
Charles's law: | the volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant. |
Combined gas law: | Boyle's, Charles's and Gay-Lusac's laws combined. |
Graham's law of effusion: | the rate of effusion of a gas is inversely proportional to the square root of the gases's molar mass. |
