Pure Substances every sample has the same

characteristic properties & composition

ELEMENTS one type of atom

Ex: iron (Fe), gold (Au), oxygen (O) (anything off the periodic table)

COMPOUNDS2 or more types of atoms:

Ex: salt (NaCl), sugar (C6H12O6), water (H2O)

Page 4: Classification of Matter. Pure Substances every sample has the same characteristic properties & composition ELEMENTS one type of atom Ex: iron.

Mixtures2 or more substances that aren’t

chemically combined and can be separated by physical means

each component keeps its own identity and properties

Page 5: Classification of Matter. Pure Substances every sample has the same characteristic properties & composition ELEMENTS one type of atom Ex: iron.

Homogeneous Mixtures uniform in

composition so NO visible parts

also called a solution

Ex: vinegar air salt water brass

brass

Brass is any alloy of copper and zinc

Page 6: Classification of Matter. Pure Substances every sample has the same characteristic properties & composition ELEMENTS one type of atom Ex: iron.

Heterogeneous Mixtures

NOT uniform in composition so you CAN see visible parts

Ex: soil concrete blood chocolate chip

cookies sand in water soda

More Examples of Mixtures

Physical Separation Techniques

Filtration- solid part is trapped by filter paper and the liquid part runs through the paper

Vaporization- where the liquid portion is evaporated off to leave solid

Page 9: Classification of Matter. Pure Substances every sample has the same characteristic properties & composition ELEMENTS one type of atom Ex: iron.

Physical Separation Techniques Decanting- when

liquid is poured off after solid has settled to bottom

Centrifuge- machine that spins a sample very quickly so that components with different densities will separate

Physical Separation Techniques

Paper Chromatography- used to separate mixtures because different parts move quicker on paper than other

PracticeDetermine whether each of the following is element, compound, homogeneous mixture or heterogeneous mixture.

air zinc chlorine granite aluminum sugar in water blood sucrose stainless steel sodium chloride

brass whole milk apple table salt soft drinks vinegar concrete sodium baking soda (NaHCO3) gravel
