Question

Write two difference between pure substance and mixture​

Answer 1

Answer:

• Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. Mixtures are physically combined structures that can be separated into their original components.

• A chemical substance is composed of one type of atom or molecule.

• A mixture is composed of different types of atoms or molecules that are not chemically bonded.

• A heterogeneous mixture is a mixture of two or more chemical substances where the various components can be visually distinguished.

• A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the solution has the same properties.

• Various separation techniques exist in order to separate matter, including include distillation, filtration, evaporation and chromatography. Matter can be in the same phase or in two different phases for this separation to take place.
