Chemistry is the study of substances and how they interact with other substances. A substance can be broken into two categories: mixtures or pure substances. In chemistry, a pure substance is an element or compound made up of one type of particle. Pure substances have a fixed structure with ...
In everyday usage, a pure substance is a material that is free of impurities or contaminants. However, the definition of a pure substance is more narrow in chemistry. In chemistry, a pure substance has a constant chemical composition. No matter where you sample a substance, it is the same....
