write comparison and difference between mixtures and compounds
Answers
The compound is the chemical combination of elements, bonded together in specific proportion.
The mixture is the physical combination of substances, bonded together in any proportion.
Answer:
The objects around us are created out of matter, and it is present in three forms, i.e. element, compound, and mixture. Chemistry is the branch of science which deals with these three forms of matter elements, compounds, and mixtures. It is difficult for many science students to understand the difference between mixtures and compounds, so here we’ve simplified it for you.
What is a Mixture?
A mixture is created when two or more substances are combined physically in indefinite proportions.
What is a Compound?
A compound is creating by mixing two or more elements together chemically and in a definite proportion.
Explanation:
The important difference between Mixtures and Compounds
Parameter Mixtures Compounds
Definition Mixtures are impure substances, made up of two or more physically mixed substances. They can be homogeneous or heterogeneous by nature. They are the pure form, made up of two or more elements that are chemically mixed. These are generally homogeneous.
Composition Substance mixed is not in a fixed ratio The ratio of the elements mixed is fixed.
Properties The properties of the mixtures also vary (not fixed) as it depends on the type of substances and the quantity by which these are being mixed. For the particular type of compound, the properties are fixed and do not vary, as the elements present in the compounds are fixed and are in the fixed ratio.
Formula Mixtures do not have a certain formula. They have a specific formula, which depends on the constituents present in it.
Separation The substances of the mixtures are easy to separate by different physical methods like filtration, chromatography, and evaporation. It is not easy to separate the elements of compounds. However, only chemical methods are useful in separating them.
Substances No new substances form from the mixtures, due to the unchangeable properties of its constituents. When we do the mixing of the chemical properties of the different constituents, there is always the formation of the new substances.
Melting/Boiling point Mixtures do not have a fixed melting or boiling point. The compound has a fixed melting and boiling point.
Heat change There is no heat change or involvement of energy while making a mixture. During the formation of the compounds, as it is a chemical reaction there is a heat change and consumption or release of energy.
Examples Alloys like brass, bismuth, chromium, etc. Compounds like Baking soda, Methane, Salt, etc.
