Agent :: Agent (n.) An active power or cause; that which has the power to produce an effect; as, a physical, chemical, or medicinal agent; as, heat is a powerful agent..

Sequence :: Sequence (n.) Simple succession, or the coming after in time, without asserting or implying causative energy; as, the reactions of chemical agents may be conceived as merely invariable sequences..

Protyle :: Protyle (n.) The hypothetical homogeneous cosmic material of the original universe, supposed to have been differentiated into what are recognized as distinct chemical elements..

Ossein :: Ossein (n.) The organic basis of bone tissue; the residue after removal of the mineral matters from bone by dilute acid; in embryonic tissue, the substance in which the mineral salts are deposited to form bone; -- called also ostein. Chemically it is the same as collagen..

Link :: Link (n.) A bond of affinity, or a unit of valence between atoms; -- applied to a unit of chemical force or attraction..

Reaction :: Reaction (n.) The mutual or reciprocal action of chemical agents upon each other, or the action upon such chemical agents of some form of energy, as heat, light, or electricity, resulting in a chemical change in one or more of these agents, with the production of new compounds or the manifestation of distinctive characters. See Blowpipe reaction, Flame reaction, under Blowpipe, and Flame..

Voltaism :: Voltaism (n.) That form of electricity which is developed by the chemical action between metals and different liquids; voltaic electricity; also, the science which treats of this form of electricity; -- called also galvanism, from Galvani, on account of his experiments showing the remarkable influence of this agent on animals..

Nitrogen :: Nitrogen (n.) A colorless nonmetallic element, tasteless and odorless, comprising four fifths of the atmosphere by volume. It is chemically very inert in the free state, and as such is incapable of supporting life (hence the name azote still used by French chemists); but it forms many important compounds, as ammonia, nitric acid, the cyanides, etc, and is a constituent of all organized living tissues, animal or vegetable. Symbol N. Atomic weight 14. It was formerly regarded as a permanent noncon

A process which consists in surrounding a solid body with the powder of other substances, and heating the whole to a degree not sufficient to cause fusion, the physical properties of the body being changed by chemical combination with powder; thus iron becomes steel by cementation with charcoal, and green glass becomes porcelain by cementation with sand..
