Reciprocity :: Reciprocity (n.) Mutual action and reaction.

Reactionary :: Reactionary (a.) Being, causing, or favoring reaction; as, reactionary movements..

Lactamide :: Lactamide (n.) An acid amide derived from lactic acid, and obtained as a white crystalline substance having a neutral reaction. It is metameric with alanine..

Recoil :: Recoil (n.) Specifically, the reaction or rebounding of a firearm when discharged..

Casein :: Casein (n.) A proteid substance present in both the animal and the vegetable kingdom. In the animal kingdom it is chiefly found in milk, and constitutes the main part of the curd separated by rennet; in the vegetable kingdom it is found more or less abundantly in the seeds of leguminous plants. Its reactions resemble those of alkali albumin..

Catalysis :: Catalysis (n.) A process by which reaction occurs in the presence of certain agents which were formerly believed to exert an influence by mere contact. It is now believed that such reactions are attended with the formation of an intermediate compound or compounds, so that by alternate composition and decomposition the agent is apparenty left unchanged; as, the catalysis of making ether from alcohol by means of sulphuric acid; or catalysis in the action of soluble ferments (as diastase, or ptyali

Barker''s Mill :: Barker's mill () A machine, invented in the 17th century, worked by a form of reaction wheel. The water flows into a vertical tube and gushes from apertures in hollow horizontal arms, causing the machine to revolve on its axis..

Preaction :: Preaction (n.) Previous action.

Benzamide :: Benzamide (n.) A transparent crystalline substance, C6H5.CO.NH2, obtained by the action of ammonia upon chloride of benzoyl, as also by several other reactions with benzoyl compounds..

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..

Revulsion :: Revulsion (n.) A sudden reaction; a sudden and complete change; -- applied to the feelings.

Coagulation :: Coagulation (n.) The change from a liquid to a thickened, curdlike, insoluble state, not by evaporation, but by some kind of chemical reaction; as, the spontaneous coagulation of freshly drawn blood; the coagulation of milk by rennet, or acid, and the coagulation of egg albumin by heat. Coagulation is generally the change of an albuminous body into an insoluble modification..

Abutment :: Abutment (n.) A fixed point or surface from which resistance or reaction is obtained, as the cylinder head of a steam engine, the fulcrum of a lever, etc..

Synthesis :: Synthesis (n.) The art or process of making a compound by putting the ingredients together, as contrasted with analysis; thus, water is made by synthesis from hydrogen and oxygen; hence, specifically, the building up of complex compounds by special reactions, whereby their component radicals are so grouped that the resulting substances are identical in every respect with the natural articles when such occur; thus, artificial alcohol, urea, indigo blue, alizarin, etc., are made by synthesis..

Incompatible :: Incompatible (a.) Incapable of being together without mutual reaction or decomposition, as certain medicines..

Protamin :: Protamin (n.) An amorphous nitrogenous substance found in the spermatic fluid of salmon. It is soluble in water, which an alkaline reaction, and unites with acids and metallic bases..
