Question

2. Differentiate mixtures and compounds.​

Answer 1

Explanation:

Compound are substances which can be formed by chemically combining two or more elements. Mixtures are substances that are formed by physically mixing two or more substances.

Answer 2

Explanation:

The differences between mixtures and compounds are tabulated below.

Difference Between Compound and Mixture

Sl. No.Differentiating PropertyCompoundMixture1DefinitionCompound are substances which can be formed by chemically combining two or more elements.Mixtures are substances that are formed by physically mixing two or more substances.2TypesCompounds can be of three types, which are: covalent compounds, metallic compounds and ionic compounds.

Note: Compounds can be classified as organic compounds or inorganic compounds depending on the presence of carbon in the molecular structure.

Mixtures are mainly of two types i.e. homogenous mixtures and heterogeneous mixtures.3Substance CategoryCompounds fall under pure substances.Mixtures can be categorized as impure substances.4Composition DetailsThe chemical composition of compounds is always fixed.A mixture can have a variable composition of the substances forming it.5NatureCompounds are always homogeneous in natureMixtures can either be homogeneous or heterogeneous in nature.6Separation of ConstituentsThe constituents of a compound can only be separated by either chemical or electrochemical methods (like extraction).Mixtures can be separated into their constituents via physical separation methods such as filtration. Thus, the separation of mixtures is relatively easier than the separation of chemical compounds.7PropertiesThe properties of compounds are unique to themselves and need not necessarily reflect the properties of the constituent elements.The constituents of a mixture do not lose their properties and so, the properties of a mixture are generally the sum of the properties of its constituents.8New SubstanceA new substance is formed after the constituents are chemically combined. So, a compound has different properties from its constituents.No new substances are formed in mixtures and their properties are dependent on the properties of their respective constituents.9Melting and Boiling PointsThe melting and boiling points of a compound are always defined.The melting and boiling points of a mixture are not defined.10ExampleWater, salt, baking soda, etc.Oil and water, sand and water, smog (smoke + fog), etc.

These were the main mixtures and compounds differences that are crucial for not only examinations but also for competitive exams.
