Pure substances combine to form new substances through chemical reactions. During a chemical reaction, the atoms of the pure substances rearrange to form new chemical bonds, leading to the creation of different compounds with unique properties. The process is governed by the laws of conservation of mass and energy.

Why these pure substances come up into mixtures?
Pure substances come up into mixtures because different substances can combine physically without undergoing a chemical reaction. These mixtures can be either homogeneous (uniform composition) or heterogeneous (non-uniform composition) depending on the interactions between the pure substances. Mixing pure substances allows for the creation of new materials with unique properties and characteristics.
