(POM) Chemical Properties Lesson

Chemical Properties

Chemical properties can be measured or observed only when matter undergoes a change to become an entirely different substance. They include flammability and reactivity. Flammability is the ability of matter to burn. Wood is flammable; iron is not. When wood burns, it changes to ashes, carbon dioxide, water vapor, and other gases. After burning, it is no longer wood. Reactivity is the ability of matter to combine chemically with other substances. For example, iron is highly reactive with oxygen. When it combines with oxygen, it forms the reddish powder called rust. Rust is not iron but an entirely different substance that consists of both iron and oxygen.
