Mixtures and Compounds are different. Let me show you how.
Mixtures | Compounds |
Don't have chemical formulas | Have Chemical formulas |
Do not have definite densities | Do have definite densities |
Do not have definite melting points | Have definite melting points |
Are not pure substances | Are pure substances |
Molecules are not chemically combined | Molecules are chemically combined |
Are separated by physical changes | Are separated by chemical reactions |
Mixtures and Compounds are not always different, they do have similarities. For example they both are made of other substances.
MIXTURES:
There are many types of mixtures. For example solutions and suspensions. Also known as Homogeneous and Heterogeneous. These are examples of homogeneous and heterogeneous mixtures.
COMPOUNDS:
Compounds are pure substances. They can be broken down,but only by chemical means. They are composed of different elements. Each compound has a set of physical properties such as melting points, density and color. Some compounds have definite boiling points but, not all of them do.
Here is an example of a compound that is made up of many different elements and has it's own set of physical properties. Such as . . . it is made up of sodium, oxygen, carbon and hydrogen. It has a definite melting point and density, but not a definite boiling point.
