General chemistry

An object whose centres of positive and negative charge do not coincide. For example, a hydrogen chloride (HCl) molecule is an electric dipole because bonding electrons are on average closer to the ...

Momentum

Chemistry; General chemistry

Momentum is a property that measures the tendency of a moving object to keep moving in the same direction. Increasing the speed of an object increases its momentum, and a heavy object will have more ...

Adsorption

Chemistry; General chemistry

Adsorption is collection of a substance on the surface of a solid or a liquid. For example, gases that make water taste bad are strongly adsorbed on charcoal granules in water filters.

Electric dipole moment

Chemistry; General chemistry

A measure of the degree of polarity of a polar molecule . Dipole moment is a vector with magnitude equal to charge separation times the distance between the centres of positive and negative charges. ...

System

Chemistry; General chemistry

In thermodynamics, the system is the part of the universe that is of interest.

Adsorption chromatography

Chemistry; General chemistry

A technique for separating or analysing mixtures that contain at least one component that is preferentially adsorbed by the stationary phase as it moves over it.

Electric field

Chemistry; General chemistry

A field of forces that act on any electric charge placed within it. The stronger the field, the stronger the force that acts on the charge. For example, the positive charge on an atomic nucleus ...
