Reaction :: Reaction (n.) The force which a body subjected to the action of a force from another body exerts upon the latter body in the opposite direction.

Magnesia :: Magnesia (n.) A light earthy white substance, consisting of magnesium oxide, and obtained by heating magnesium hydrate or carbonate, or by burning magnesium. It has a slightly alkaline reaction, and is used in medicine as a mild antacid laxative. See Magnesium..

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..

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..

Lactucin :: Lactucin (n.) A white, crystalline substance, having a bitter taste and a neutral reaction, and forming one of the essential ingredients of lactucarium..

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..

Reflux :: Reflux (n.) A flowing back, as the return of a fluid; ebb; reaction; as, the flux and reflux of the tides..

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..

Earth :: Earth (n.) A similar oxide, having a slight alkaline reaction, as lime, magnesia, strontia, baryta..

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

Reactive :: Reactive (a.) Having power to react; tending to reaction; of the nature of reaction.

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.

Acid :: Acid (a.) Of or pertaining to an acid; as, acid reaction..

Reaction :: Reaction (n.) Backward tendency or movement after revolution, reform, or great progress in any direction..

Test :: Test (n.) A reaction employed to recognize or distinguish any particular substance or constituent of a compound, as the production of some characteristic precipitate; also, the reagent employed to produce such reaction; thus, the ordinary test for sulphuric acid is the production of a white insoluble precipitate of barium sulphate by means of some soluble barium salt..

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..

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

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..

Wheel :: Wheel (n.) A firework which, while burning, is caused to revolve on an axis by the reaction of the escaping gases..

Turbine :: Turbine (n.) A water wheel, commonly horizontal, variously constructed, but usually having a series of curved floats or buckets, against which the water acts by its impulse or reaction in flowing either outward from a central chamber, inward from an external casing, or from above downward, etc.; -- also called turbine wheel..
