A process in which one substance is transformed into another.

Reaction between chemicals where there is a change in the chemical composition of the elements or compounds concerned.

A process leading to chemical changes in matter; involves the making and/or breaking of chemical bonds.

process that involves a change in atoms, ions, or molecules of the substances (reagents) involved.

A chemical reaction is a chemical change which forms new substances.Also Known As: reaction, chemical changeExamples: The chemical reaction H2(g) + ½ O2(g) → H2O(l) describes the formation of water fr [..]

A process that leads to the transformation of one set of chemical substances to another.

  The transformation of substances by the rearrangement of their atoms.

The formation of new substances from one or more reactants, by breaking existing electrical bonds and creating others.

Change that takes place when two or more substances (reactants) interact to form new substances (products).

A change that alters the chemical composition of a substance.

A process in which the composition or structure of a chemical is changed to form another substance.

A process by which one substance is transformed into another; a process in which a chemical change occurs (Lessons 9, 12)

a process by which one substance is chemically converted to another. Chemical reactions involve the formation or destruction of bonds between atoms.

Any change that comes about through the chemical action of substances on each other, i.e. rusting and combustion are both chemical reactions involving the oxidation of a substance.

A process that results in the interconversion of chemical species. Chemical reactions may be elementary reactions or stepwise reactions. (It should be noted that this definition includes experimentally observable interconversions of conformers.) Detectable chemical reactions normally involve sets of molecular entities, as indicated by this definiti [..]

Interactions in which atoms exchange or share electrons, forming new chemicals.

A chemical process in which substances are changed into different substances. Chemical reactions are manifested by the disappearance of properties characteristic of the starting materials and the appearance of new properties that distinguish the products. Examples of chemical reactions include burning of wood, fermentation of crops to make alcohol, [..]

The interaction of two or more substances resulting in chemical changes in them.

(chemistry) A process, typically involving the breaking or making of interatomic bonds, in which one or more substances are changed into others.
