Compounds <br /> A compound is made up of two or more types of elements (e.g. water and carbon dioxide) that are chemically combined in a set ratio. They cannot be broken down into two or more simpler substances by physical means, only by chemical means. Properties of compounds differ from those of their elements.
A compound is a pure substance that is made up of two or more different elements that are chemically combined. Several common compounds include water (H2O), limestone (CaCO3), salt (NaCl) and carbon dioxide (CO2). It is not easy to separate the elements in a compound because it requires a chemical reaction.his ability to react to oxygen to form rust is called a chemical property. A chemical property is a characteristic that can only be determined by changing the chemical identity of a substance. What we started with was iron, but when it reacts with the oxygen in the air, it turns into iron oxide, or rust.
