What is Pure Substance? Pure Substance is substances that are made up of only one type of atom or only one type off molecule. Pure substance is either a element or a compound. Ex carbon is an element and sugar is a compound.
Water is a pure substance.
Element- a class of substances that cannot be separated into simpler substances by chemical means.
Compound- A thing that is composed of two or more separated elements.
The organic in coal are composed of the elements carbon, hydrogen, oxygen,nitrogen, sulfur, and trace amount of a variety of other elements.
Mixture- a substance made by mixing other elements together.
This is a mixture because the m&ms are all different colors but you can still divide them by there colors.
Homogeneous mixture- of the same kind ; alike... For example water itself is a homogeneous mixture It often contains dissolved minerals and gases, but these are dissolved throughout the water.
Heterogeneous Mixture- any combination of substances that does not have uniform composition and properties; a mixture of physically distinct substances with different properties
Homogeneous solution- is a mixture of two or more components that have a uniform appearance and composition.
Heterogeneous suspension- A suspension is a heterogeneous mixture in which solute-like particles settle out of a solvent-like phase some time after their introduction. We apply the word 'suspension' when particles are big enough to eventually settle.An example of a suspension is a mixture of water and sand. When mixed up, the sand will disperse throughout the water. If left alone, the sand will settle to the bottom.
Heterogeneous Colloid- A colloid is a mixture where very small particles of one substance are evenly distributed throughout another substance.
