Here are some key points to remember:
* Chemical properties are not easily observed without changing the substance. They are different from physical properties, which can be observed without altering the substance's chemical composition (like color, texture, or density).
* Chemical properties describe how a substance reacts with other substances. This could be its flammability (how easily it burns), its reactivity with acids or bases, its tendency to corrode, or its ability to decompose.
* Chemical properties can be used to identify and classify substances. For example, knowing the chemical properties of a substance can help determine its potential uses and hazards.
Examples of Chemical Properties:
* Flammability: The ability of a substance to burn in the presence of oxygen.
* Reactivity: How readily a substance reacts with other substances, like acids or bases.
* Corrosion: The tendency of a substance to deteriorate when exposed to the environment, such as rusting of iron.
* Stability: How resistant a substance is to decomposition or change.
* Toxicity: The degree to which a substance is poisonous or harmful.
In contrast to physical properties, chemical properties are not easily reversible. Once a chemical reaction has occurred, the substance has been fundamentally altered.
