Detailed explanation-1: -A chemical property describes the ability of a substance to undergo a specific chemical change. To identify a chemical property, we look for a chemical change. A chemical change always produces one or more types of matter that differ from the matter present before the change.
Detailed explanation-2: -One chemical property of matter is reactivity. Reactivity is the ability of a substance to change into a new substance. One kind of reactivity is flammability.
Detailed explanation-3: -Some properties, such as solubility, melting point, boiling point, and density are independent of the amount of substance being examined. These properties are known as intensive properties and are used to identify a substance.
Detailed explanation-4: -Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
