differences between mixtures and compounds
In a mixture, the molecules of two or more substances are mixed to form alloys, solutions, suspensions and colloids. When a compound is formed, energy is given off or absorbed but when a mixture is formed, no energy is given off or absorbed.
Other examples of mixtures are air (mixture of gases) and brass (mixture of copper and zinc). Summary: 1. In a compound, there is chemical union between the elements, while there is no chemical reaction or bonding between elements in a mixture.
The components of a compound can only be separated using chemical methods. The constituents of a mixture can be separated using physical methods. For example, a mixture of copper and phosphorus can be separated using a magnet but the same cannot be done for copper phosphide. A common example of a mixture is air. Carbon dioxide is a good example of compound.
