The two types of matter that are pure substances are elements and compounds.
An enormous number of compounds can by purified.

Pure salt, NaCL, is a chemical compound made from two elements. So yes it is a combination of two pure substances
No. This is because a pure substance is a compound (or element) and can only be separated chemically but mixtures can be separated physically. P.S. This answer was written by a 14 year old from Dearborn Michigan

The main reason is simply one of dichotomy: either a substance is pure or it is not pure. If it is not pure then it consists of two (or more) substances which are chemically separate - a mixture.
Pure substances and mixed substances
Some people divide matter into pure substances and mixtures. Pure substances are elements and compounds. Mixtures include homogeneous and heterogeneous mixtures. Some people divide matter into homogeneous matter and heterogeneous matter. Homogeneous matter includes pure substances and homogeneous mixtures (solutions). Heterogeneous matter is heterogeneous mixtures.
The two primary types of homogeneous matter are elements and compounds. Homogeneous matter is a substance that has uniform properties and compositions.
The two main branches are pure substances and mixtures.
Pure substances (elements and compunds) and mixed substances (mixtures, solutions, alloys).
The matter can be decomposed into two parts: - the first part is named electrocinematicoxyme or positive matter - the second and last part is named transvakineticase or neutral matter. This was demonstrated by Alibert Montrocq, a French astrophysicist in 1926 and is known as the dual experimentation of Montroq (entered the history with the wrong spelling, too bad for Mr Montrocq).
- One basic division is into pure substances (elements and compounds) and mixed substances (mixtures, solutions, alloys). Mixed substances do not contain molecules that are all the same.- Another way to classify matter is:organic (from living things) and inorganic(natural elements and compounds).

There are three main states of matter; solid, liquid and gas. There are two categories of matter; pure substances and mixtures. Pure substances are either elements such as iron, silver, gold or uranium or they are compounds of elements such as water (H20), carbon dioxide (CO2), ad infinitum.
