General chemistry
Fahrenheit
Chemistry; General chemistry
A temperature scale proposed by Daniel Gabriel Fahrenheit (1686-1736) which uses the melting point of ice (32°F) and the boiling point of water at one atmosphere (212°F) as calibration points. ...
Gibbs free energy of formation
Chemistry; General chemistry
The change in Gibbs free energy that accompanies the formation of one mole of a compound from its elements in their most stable form.
Helmholtz free energy
Chemistry; General chemistry
A thermodynamic property that can be used to predict whether a process will occur spontaneously at constant volume and temperature. Helmholtz free energy A is defined as A = U - TS where U, T and S ...
Henry's Law
Chemistry; General chemistry
Henry's law predicts that the solubility (C) of a gas or volatile substance in a liquid is proportional to the partial pressure (P) of the substance over the liquid: P = k C where k is called the ...
Hertz
Chemistry; General chemistry
The SI unit of frequency , equal to one cycle of the wave per second (s-1).
Hess's law
Chemistry; General chemistry
The heat released or absorbed by a process is the same no matter how many steps the process takes. For example, given a reaction A B, Hess's law says that H for the reaction is the same whether the ...
Hund's rule
Chemistry; General chemistry
A rule of thumb stating that subshells fill so that the number of unpaired spins is maximized, or "spread them out and line them up."
