Answer 1

Answer:

ANS.1   A solution is a homogeneous mixture of two or more substances. A solution has a solvent and a solute as its components. ... The component of the solution that is dissolved in the solvent (usually present in lesser quantity) is called the solute.

ANS.2  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 which are not chemically combined with each other. The components of a mixture each keep their original properties.

ANS.3  The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant.

Answer 2

A colloidal solution

${\blue{\underline {\underline{ \mathtt{\pink{colloidal \: solution:-}}}}}}$

is a heterogeneous system in which one substance is dispersed (dispersed phase) as very fine particles in another substance called dispersion medium. It is the intermediate system between a solution and a suspension. The size of colloidal particles is between 1 nm and 1000 nm.

${\blue{\underline{\blue{\underline {\underline{ \mathtt{\pink{mixture \: {\blue and \: its \: properties:-}}}}}}}}}$

A mixture is a substance that is made by combining two or more substances without any chemical bonding .Here the identities of the constituents are retained. Mixture is capable of being separated into its constituents. Mixtures es basically of two types-homogenous and heterogeneous mixtures.

${\blue{\underline {\underline{ \mathtt{\pink{Law \: of \: conservation \: of \: \: matter :-}}}}}}$

a fundamental principle of classical physics that matter cannot be created or destroyed in an isolated system.
