What are the chemical properties of matter?

Chemical properties describe how a substance interacts with other substances to form new products. Key chemical properties include:Main chemical properties:- Reactivity - How readily a substance undergoes chemical change- Flammability - Ability to burn in presence of oxygen- Toxicity - Degree to which a substance can damage organisms- Acidity/Basicity - Measured by pH level- Oxidation states - Tendency to gain or lose electrons- Chemical stability - Resistance to chemical change- Heat of combustion - Energy released during burning- Radioactivity - Emission of radiation from atomic nucleiUnlike physical properties (color, density), chemical properties can only be observed during chemical reactions that change the substance's molecular structure.

To understand the difference between physical and chemical properties, here's a simple test: If the change can be reversed easily, it's probably physical. If it creates a new substance, it's chemical.For example:- Physical change: Ice melting to water (still H₂O)- Chemical change: Wood burning to ash (new substances formed)Chemical properties matter because they determine:- How we use materials (non-reactive containers for chemicals)- Safety handling (flammable materials need special storage)- Environmental impact (how substances break down in nature)- Industrial applications (catalysts, manufacturing processes)Understanding these properties helps chemists create new materials and predict how substances will behave in different situations.
