The given diagram has to be classified as a mixture, an element or a compound. The given diagram is, Figure 1 Concept Introduction: Matter can be classified into two type’s namely pure substance and mixture. Pure substance: A single component that has a constant composition, irrespective of the sample size and the sample origin is called as pure substance. A pure substance could not be broken down to other pure substances by any physical change. Example: Water, sugar etc. A pure substance can be classified into an element and a compound. Element: A pure substance, which cannot be broken down into smaller substances by a chemical reaction is called as an element. Example: Hydrogen gas, Magnesium ribbon and copper wire etc. Compound: A pure substance that is formed by combination of two or more elements by chemical process is called as a compound. Example: Sodium chloride is a compound because it is formed from elements sodium and chlorine. Mixture: A mixture consists of more than one substance and the composition of a mixture is dependent on the sample. The separation of mixture into its components can be done by physical changes.
