Today in our Chemistry Class, we discussed the Classifications of Matter- such as Homogeneous and Heterogeneous Substances.
Homogeneous Substances can be divided into Pure Substances (Elements and Compounds) and Homogeneous Mixtures (Solutions). While Heterogenous Substances has one category, Mechanical Mixtures which are mixtures that we can seperate manually with our own hands.
Pure Substances are made up of two groups, Elements and Compounds. Elements are substances that cannot be broken down into simpler substances by chemical reactions (Hydrogen, Oxygen, Carbon, Nitrogen, etc). Compounds on the other hand are substances that are made up of two or more elements and can be changed into elements by chemical reactions (Water, Salt, Sugar, Carbon Dioxide, etc).
In order to separate Compounds, a process called Electrolysis is done. Electrolysis can split the compound apart into its constituent elements through and electric current. This process can also be an example of a Chemical Change.
Before we can further study Chemistry, we must have to understand the different classifications of Matter. These are simple stuffs that can help us go a long way with Chemistry. :)

Homogeneous Substances are substances that contains only one visible component (Example: Water). While Homogeneous Substances are substances that contain more than one visible component. (Example: Chocolate Chip Cookies)Homogeneous Substances can be divided into Pure Substances (Elements and Compounds) and Homogeneous Mixtures (Solutions).
