2. Write any three differences between mixture and compounds
Answers
Answer:
Difference between compound and mixture can be best understood if their compositions and other related details are completely known. The compound and mixture difference is one of the most commonly asked questions in chemistry. In this article, the detailed differences between a compound and mixture in tabular form are given.
It is important to know what compounds and mixtures are before going to their differences. To get a detailed idea about mixtures and compounds, visit the following links:

After knowing their details, it is now easy to understand the main comparisons and differences between mixtures and compounds. Check the following table to know the main differences between a compound and a mixture.
Difference Between Compound and Mixture
Sl. No. Differentiating Property Compound Mixture
1 Definition 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.
2 Types Compounds 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.
3 Substance Category Compounds fall under pure substances. Mixtures can be categorized as impure substances.
4 Composition Details The chemical composition of compounds is always fixed. A mixture can have a variable composition of the substances forming it.
5 Nature Compounds are always homogeneous in nature Mixtures can either be homogeneous or heterogeneous in nature.
6 Separation of Constituents The 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.
7 Properties The properties of compounds are unique to themselves and need not necessarily reflect the properties of the constituent elements. The constituents of a mixture does not lose their properties and so, the properties of a mixture are generally the sum of the properties of its constituents.
8 New Substance A 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.
9 Melting and Boiling Points The melting & boiling points of a compound are always defined. The melting and boiling points of a mixture is not defined.
10 Example Water, salt, baking soda, etc. Oil and water, sand and water, smog (smoke + fog), etc
Answer:
1. Mixtures are impure substance while compounds are pure
2. Mixtures can be physically separated while compounds need to be separated chemically
3.Compounds are homogeneous while mixtures are heterogeneous
