Chemical change
From Biocrawler, the free encyclopedia.
A chemical change is a process in which reactants are changed into one or more different products. A chemical change occurs whenever compounds are formed or decomposed. During this reaction, there is a rearrangement of atoms that makes or breaks chemical bonds. This change is usually not reversible.
There are several different types of chemical change. These include synthesis, decomposition, single displacement, double displacement, neutralization, precipitation and redox.
Indicators of a chemical change include a color change, the formation of a precipitate, the formation of gas, or a change in temperature.
When new substances are formed, a chemical change has occurred, and a chemical reaction has taken place.
