3) Distinguish between compound and mixtute. maga Compound Mixture Proportion of constituent elements are fixed. Properties of compounds are different from their constituent elements. w No chemical change takes place. Physical method is used to separate components of the mixture.

Answer:
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.

Answer:
compound and mixture
Explanation:
- A compound is a substance that are formed by two or more chemical elements.
- The mixture is a substance created from two or more matter that can be separate with the help of physical methods.
