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.

Chemistry is a familiar school subject

Everyone liked to observe the reaction of reagents. But few know interesting facts about chemistry, which we will discuss in this article.

Primary Voltaic Cells

Voltaic cells that cannot be recharged, no further chemical reaction is possible once the reactants are consumed.

Binary Compound

A compound consisting of two elements, may be ionic or covalent.

Metallic Conduction

Conduction of electrical current through a metal or along a metallic surface.

Chain Reaction

A reaction that, once initiated, sustains itself and expands. This is a reaction in which reactive species, such as radicals, are produced in more than one step. These reactive species, radicals, propagate the chain reaction.
