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.

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..

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..

Reactionist :: Reactionist (n.) A reactionary.

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

Xanthoproteic :: Xanthoproteic (a.) Pertaining to, or derived from, xanthoprotein; showing the characters of xanthoprotein; as, xanthoproteic acid; the xanthoproteic reaction for albumin..

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..

Reactionary :: Reactionary (n.) One who favors reaction, or seeks to undo political progress or revolution..

Resist :: Resist (v. t.) To counteract, as a force, by inertia or reaction..

Basic :: Basic (a.) Apparently alkaline, as certain normal salts which exhibit alkaline reactions with test paper..

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

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..

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

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

Electro-muscular :: Electro-muscular (a.) Pertaining the reaction (contraction) of the muscles under electricity, or their sensibility to it..

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..

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.
