Let us observe several examples of matter and find out how they differ. We may first classify them according to two general categories-homogeneous or heterogeneous. This classification is based on easily observable properties.so as not to get confused,try to rememenber the origin of each term. The term homogenous comes from homo ( the same) and…[Read more]

. These are properties that are permanent or that depend on the kind of substance itself. For example, we kn0w that pure water is c0l0rless and is a liquid at room temperature; does n0t burn,freezes at 0’c, and boils at 100’C at sea level. Carbon dioxide is a colorless ,odorless gas at room temperature and does not burn. Ethanol, the common…[Read more]

Any material under study is called a system. Chemists in general are interested in the study of chemical or material systems. When we study a chemical system,we first observe and describe its properties. If we want to group different kinds of matter,we should lo0k for similarities and differences in their instrinsic properties. These are…[Read more]

Compounds may be classified based on the presence of the element caraon. There is a a very large group of compounds containing the element carbon that possess a unique set of properties. They number in milli0ns but it is convenient to study them as a group.some are naturally occurring and and mostly present in living organisms or are of living…[Read more]
