Mixtures can be Heterogeneous Mixture or HOMOGENEOUS Mixture (Solutions)
Pure Substances can be : ELEMENTS or COMPOUNDS
Explanation:
There are two major classifications of matter - pure substances and mixtures. A pure substance can further be classified into elements and compounds. Elements are made up of one kind of atom and cannot be broken down or transformed by a chemical reaction into a different element. Examples are carbon, hydrogen, iron, or oxygen. All other elements can be found in the periodic table of elements. Compounds are made of two or more elements that are chemically bonded. Components of compounds are also in fixed ratio or amount. Examples of compounds are water which is made of hydrogen and atom, carbon dioxide which is made of carbon and oxygen, and salt or sodium chloride which is made of sodium and chlorine.
A mixture is composed of different types of substances that are not chemically bonded. A heterogeneous mixture is a mixture of two or more substances where the various components can be easily distinguished. Examples are mixed nuts, sandwiches, and salad. A homogeneous mixture is a type of mixture in which the composition is uniform and components are not easily distinguished. They are referred to as solutions. Examples are the salt solution, orange juice, or alcohol.
