list four difference between a compound and a mixture
Answers
Explanation:
Parameter Compound Mixture
Meaning A compound is a pure form comprising of two or more elements in a chemical combination A mixture is an impure substance involving two or more substances that are physically mixed.
Composition The presence of elements in compounds is in a definite quantity The presence of substances in mixtures is not in a definite quantity
Formula A compound certainly has a specific formula on the basis of its constituents Mixtures are devoid of a chemical formula
Properties The properties of a specific type of compound are definite and there is no variation in them The properties of a mixture tend to vary due to their dependence on the type of substances present
Substances The formation of new substances always results in a compound because of the mixing of properties of the various elements Formation of new substances does not take place from the mixtures because the properties of its constituents are not changeable
Separation The elements of a compound are not easy to separate by physical methods The substances of a mixture are certainly easier to separate by various physical methods like chromatography, evaporation, filtration, etc
Change of heat There is a change of heat during the formation of a particular compound There is no heat change in mixtures when their formation takes place
Melting or Boiling point Compounds have an unchangeable definite melting or boiling point Mixtures lack a definite melting or boiling point
Examples of Compound and Mixture Methane, salt, baking soda, etc Brass, chromium, bismuth, etc
Explanation:
Difference Between Compound and Mixture
The difference between compound and mixture plays an important role in the field of chemistry as many people can easily confuse between the two. Moreover, the mixture refers to a substance that has two or more substances mixed together physically. In contrast, compound means a combination of two or more elements in a definite ratio. Learn more about the difference between compound and mixture to better understand the two concepts.
Definition of Compound
Compound refers to a pure form that comprises of two or more substances by way of chemical combination. A difference between compound and mixture can be seen from the fact that compounds are generally homogenous.
Definition of Mixture
Mixture refers to an impure substance that comprises of multiple physically mixed substances. Furthermore, a mixture can be either heterogeneous or homogeneous in nature. Moreover, the ratio of the substances present in the mixture is not of definite quantity and hence can vary.
