Classifications of Matter

Matter Has mass Takes up space ex…. Chemistry is the study of MATTER!

Physical means: a. Sorting b. Filtering c. Heating and cooling Each component keeps the same characteristics after separation

Mixtures Contain more than one kind of matter Can be separated physically

Types of Mixtures Homogeneous mixtures – are the same throughout; every sample has the same ratio of ingredients Ex: Chocolate Ice Cream Heterogeneous Mixtures – vary throughout; each sample has the potential to have a different ratio from the next Ex: Chicken noodle soup

Mixture Examples Petroleum (Crude Oil) – 1,000,000 molecular compounds Milk – Fat, Whey, Liquids Soda – Carbonated water, corn syrup, caramel color, phosphoric acid, natural flavors and caffeine Paint – Pigment, Latex, thinning agents

Substances Cannot be separated by physical means May contain more than one kind of matter but can only be separated by chemical means

Types of Substances Elements – Contain only one kind of matter; specifically one kind of atom Compounds – contain two or more elements and cannot be separated without chemical means

Review Questions: Types of matter What are the four main classifications of matter? Give two examples of each type of matter What are three ways to separate a mixture by physical means? What kind of substance is Iron?
