composition of a mixture

Mixtures - A mixture is a combination of two or more elements or compounds in any proportion so that the components do not lose their identity. Air is an example of a mixture (several gases mix to form air). Mixtures are of two types, homogeneous and heteroge..

Complex mixture of hydrocarbons, chiefly alkane..

Based on the composition, mixtures can be broadly divided into three groups depending on whether the constituents are elements or compounds or bo..

Azeotropic Mixtures - In case of solutions showing positive deviation from Raoult's law, at one of the intermediate compositions, the total vapor pressure is the highest and the boiling point is the lowest. Similarly in case of solutions showing negative deviations from Raoult's..

Composition of Air - For thousands of years, air was considered to be a mixture of many gases. The true composition of air was not known for a long time. Air is a mixture of various gases. The main gases present in air are nitrogen (78.1% by volume) and oxyge..

Butane with small quantities of ethane and propane. These gases can be liquified under pressure and bottled in cylinders. By itself LPG is odourless. On leakage, it is toxic if inhaled. It also forms an explosive mixture with air. LPG can be hazardous if handled carelessly. A strong smel..

Impure Substances - Mixtures - "Impure substances are commonly called mixtures." The constituents of a mixture may be elements, compounds, or both. These substances may be present in any proportion and exhibit their individual properties. Mixtures can be homo..

Mixtures Compounds A mixture can be separated into its constituents by physical processes (filtration, evaporation, sublimation, distillation) A compound cannot be separated into its constituents by physical processes. It can be separated by chemical means A h..
