Explosive

A chemical or compound that causes a sudden, almost instantaneous release or pressure, gas, heat and light when subjected to sudden shock, pressure, high temperature or applied potential.

Nonpolar Bond

Covalent bond in which electron density is symmetrically distributed.

Solubility Product Principle

The solubility product constant expression for a slightly soluble compound is the product of the concentrations of the constituent ions, each raised to the power that corresponds to the number of ions in one formula unit.

Standard Molar Enthalphy of Formation

Coordinate Covalent Bond

A covalent bond in which both shared electrons are donated by the same atom, a bond between a Lewis base and a Lewis acid.

Disproportionation Reactions

Redox reactions in which the oxidizing agent and the reducing agent are the same species.

Le Chatelier's Principle

States that a system at equilibrium, or striving to attain equilibrium, responds in such a way as to counteract any stress placed upon it.
If a stress (change of conditions) is applied to a system at equilibrium, the system shifts in the direction that reduces stress.
