Chemical Change:
Chemical change is the process in which one or more substances are transformed into new substances with different physical and chemical properties. This change involves the breaking and forming of chemical bonds. When a chemical change occurs, new substances are formed.
Explanation:
During a chemical change, the original substances undergo a chemical reaction to produce new substances. This can involve the rearrangement of atoms, the breaking of old bonds, and the formation of new bonds. These new substances may have different properties such as color, odor, density, or chemical composition compared to the original substances.
Example:
An example of a chemical change is the rusting of iron. When iron reacts with oxygen and water in the air, it forms iron oxide (rust). The properties of iron oxide are different from those of iron, as rust is brittle and reddish-brown in color while iron is malleable and silver-gray.
Conclusion:
In summary, a chemical change results in the formation of new substances with different properties. This distinguishes chemical changes from physical changes, which do not involve the formation of new substances.
