a change in which one or more kinds of matter are transformed into a new kind
reaction; chemical reaction. Compare with physical change. A chemical change is a dissociation, recombination, or rearrangement of atoms.
a change in the chemical structure or composition of a substance
Interaction between chemicals in which there is a change in the chemical composition of the elements or compounds involved. Compare nuclear change, physical change.
a change in which one or more new substances with new properties are formed. (see chemical reaction, physical change)
Rearrangement of the atoms, ions or radicals or one or more substances, resulting in the formation of new substances, often having entirely different properties. Also known as a chemical reaction.
(chemistry) any process determined by the atomic and molecular composition and structure of the substances involved
a change in matter that occurs on
a change in which one kind of matter is changed into a different type of matter
a change in which something new is formed
a chemical process that produces one or more substances that are different from those that were present before the process occurred
a chemical reaction in which a sample of matter is transformed into completely different substances
a process in which (A chemical substance that is present at the start of a chemical reaction) reactants are changed into one or more different (An artifact that
a change in which one or more new substqances are produced with properties different from those of teh starting substance(s)
the change of substances into other substances through a reorganization of the atoms; a chemical reaction.
A change in a substance resulting in an entirely different substance with different properties from the first.
When a new substance is produced and the properties are different than the original compound/element, a chemical change has occurred.
a change in the chemical composition of a substance to produce a new material with new properties (An example of a chemical change is wood turning to ash and smoke when it burns.)
A chemical change is one in which there is a new substance formed.
What happens when atoms change their bonding to form different molecules. Find out why The DJ for Dr. Art's 50th Anniversary Ball had to use professional wrestlers to model chemical change (p.56-57).
Every "pigment" added to the base material contains metal ions. The application of the laser changes the crystal structure of the metal ions and the amount of hydration in the crystal. This causes a chemical change in the composition of the pigment component, resulting in a concentration of the pigment and a change in color.
A chemical change involves the change in a substance through chemical reactions. The chemical reactants form a new product with equal mass. The following is a list of evidence that can indicate that a chemical change took place.
