General chemistry
MSG
Chemistry; General chemistry
MSG is monosodium glutamate , used as a flavour enhancer in many foods.
Newtonian fluid
Chemistry; General chemistry
A fluid whose viscosity doesn't depend on gradients in flow speed. Gases and low-molecular weight liquids are usually Newtonian fluids.
Non-newtonian fluid
Chemistry; General chemistry
A fluid whose viscosity changes when the gradient in flow speed changes. Colloidal suspensions and polymer solutions like ketchup and starch/water paste are non-Newtonian fluids.
Pauli principle
Chemistry; General chemistry
No two electrons in an atom can have the same set of 4 quantum numbers. Because the n, , and m quantum numbers address a particular orbital, and because the ms quantum number has only two possible ...
PKa
Chemistry; General chemistry
The pKa of an acid is minus the base-10 log of its acid dissociation constant , pKa = - log Ka. For example, a pKa of 5 is equivalent to an acid dissociation constant of 10-5.
PKb
Chemistry; General chemistry
The pKb of an base is minus the base-10 log of its base hydrolysis constant , pKb = - log Kb. For example, a pKb of 5 is equivalent to an base hydrolysis constant of 10-5.
Planck's constant
Chemistry; General chemistry
A proportionality constant that relates the energy carried by a photon to its frequency . Planck's constant has a value of 6.6262 × 10-34 J s.
