Classify pure substances on the bases of the physical properties?
Answers
Answer:
Hi friends
Explanation:
The physical properties of a pure substance include well-defined melting and boiling points. The purity of a substance also impacts the chemical properties of a substance by reducing the chances of unexpected products being formed if impurities are present within the substance.

Answer:
pue substances are classified into two types : elements and compounds
Explanation:
Compound Element
Definition A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom.
Composition Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule. Elements that compose the compound are chemically combined. Elements contain only one type of atom. Each atom has the same atomic number i.e., the same number of protons in their nucleus.
Ability to break down A compound can be separated into simpler substances by chemical methods/reactions. Elements cannot be broken down into simpler substances by chemical reactions.
Types A huge, virtually limitless, number of chemical compounds can be created. Compounds are classified into molecular compounds, ionic compounds, intermetallic compounds and complexes. There are about 117 elements that have been observed. Can be classified as metal, non-metal or metalloid.
Representation A compound is represented using its chemical formula that represents the symbols of its constituent elements and the number of atoms of each element in one molecule of the compound. An element is represented using symbols.
Examples Water (H2O), Sodium chloride (NaCl), Sodium bicarbonate (NaHCO3) etc. Hydrogen (H), Oxygen (O), Sodium (Na), Chlorine (Cl), Carbon (C), Iron (Fe), copper (Cu), silver (Ag), gold (Au) etc.
