Introduction
You most likely run over one or different types of a mixture in your everyday life. The air that you inhale is the commonest form of a mixture. Did you realize that? Today, we will look into the impure substances or mixtures, as they are normally called.
Composition of Matter
Above all else, you know, you can arrange matter into two kinds:
Pure Substances: These are again arranged into elements and compounds.
Impure Substances: All mixtures are viewed as impure substances.
What is a Mixture?
Mixtures are the substances composed of two or more forms of matter. You can separate them by physical methods. Such examples include a mixture of salt and water, a mixture of sugar and water, different gases, air, etc. In any mixture, the various components do not form through any kind of chemical changes. Therefore, the components’ individual properties remain intact.
In other words, a mixture is a thing that you get when you combine two substances so that no chemical reaction happens between the substances, and you can separate them once more. In a mixture, every component keeps up its own chemical identity. Normally mechanical mixing combines components of a mixture, different procedures may give a mixture (e.g., diffusion, osmosis).
Answer:
B)The result formed due to the combination of substances does not lose its individuality nor are they combined chemically. Mixtures are the one product of a mechanical blending or mixing of chemical substances such as elements and compounds.
General Properties of Mixtures
Mixtures are made up of two or more substances that are not chemically combined with each other. The properties of mixtures are listed below.
The components of a mixture each keep their original properties.
The separation of components can be easily done.
The proportion of the components is variable.
