Excited state
An electronic state having a higher energy than the ground state.Exothermic reaction
Exothermic reaction
A reaction that gives off heat (negative ∆H) to the surroundings as the reaction proceeds.f subshell
f subshell
The subshells corresponding to the angular momentum quantum number l = 3, found in the
fourth and higher principal energy levels, each containing seven orbitals.
Faraday (F)
Faraday (F)
The total charge on 1 mole of electrons (1 F = 96,487 coulombs).Fatty acids
Fatty acids
Carboxylic acids with long hydrocarbon chains, derived from the hydrolysis of fats.First law of thermodynamics
First law of thermodynamics
The law stating that the total energy of a system and its surroundings remains constant. Also
expressed as ∆E = Q – W: the change in energy of a system is equal to the heat added to it minus the
work done by it.
