Chemistry ­ Study of matter and the changes it undergoes

LT MATTER 1: Identify the different types of matter including elements, compounds, mixtures and pure substances.

Sep 11­8:10 PM

All matter is made up of tiny particles called __________ .

Pure substances

Element  ­ cannot be separated into simpler substances. Made up of only one type of atom.C, O2, Cu, S8Elements are listed in the periodic table.

Sep 11­10:30 PM Sep 2­9:14 PM

CompoundMade up of more than one type of atom. The different atoms are chemically bonded.Sodium Chloride NaCl

Elements and compounds are pure substances.

Pure substances have uniform and unchanging composition

MixturesCombination of two or more pure substances.Each pure substance retains its individual properties.

Heterogeneous MixtureIndividual substances remain distinct.Mixture does not blend smoothly.

Matter can undergo change.Physical Change (Composition does not change)

• One or more physical properties are altered • Size, shape, color and state of matter• Grinding, melting, dissolving and        evaporating are physical changes.

No new substance or substances are formed as a result of physical change.

LT MATTER 3: Differentiate between physical and chemical changes

Chemical ChangeChemical change (Composition of the substance changes)

• results in the formation of one or more new substances• these new substances differ in chemical properties and composition from the original substance• iron rusting and paper burning are 2 examples of chemical change

Recognizing Chemical Change

Formation of a new substanceA gas is evolvedColor change

OdorEnergy is absorbed or given out

Dec 2­9:43 PM

Physical property ­ can be observed without changing the composition of the substance

Ex: density, boiling point, melting point

Chemical property ­ observed when the composition of the substance changes.

Ex: reaction with air, reaction with an acid
