Reaction (n.)

Reactionary :: Reactionary (n.) One who favors reaction, or seeks to undo political progress or revolution..
Bromoform :: Bromoform (n.) A colorless liquid, CHBr3, having an agreeable odor and sweetish taste. It is produced by the simultaneous action of bromine and caustic potash upon wood spirit, alcohol, or acetone, as also by certain other reactions. In composition it is the same as chloroform, with the substitution of bromine for chlorine. It is somewhat similar to chloroform in its effects..
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..
Water Wheel :: Water wheel () Any wheel for propelling machinery or for other purposes, that is made to rotate by the direct action of water; -- called an overshot wheel when the water is applied at the top, an undershot wheel when at the bottom, a breast wheel when at an intermediate point; other forms are called reaction wheel, vortex wheel, turbine wheel, etc..
Reactionary :: Reactionary (a.) Being, causing, or favoring reaction; as, reactionary movements..
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

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..
Revulsion :: Revulsion (n.) A sudden reaction; a sudden and complete change; -- applied to the feelings.
Reflux :: Reflux (n.) A flowing back, as the return of a fluid; ebb; reaction; as, the flux and reflux of the tides..
Reaction :: Reaction (n.) Any action in resisting other action or force; counter tendency; movement in a contrary direction; reverse action.
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..
Basic :: Basic (a.) Apparently alkaline, as certain normal salts which exhibit alkaline reactions with test paper..
Reaction :: Reaction (n.) An action induced by vital resistance to some other action; depression or exhaustion of vital force consequent on overexertion or overstimulation; heightened activity and overaction succeeding depression or shock.
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..

Reflex :: Reflex (a.) Produced in reaction, in resistance, or in return..
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..
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..
Incompatible :: Incompatible (a.) Incapable of being together without mutual reaction or decomposition, as certain medicines..
