Chemistry Properties of Matter 1 Name __________________________________ 8-14-13 LEARNING GOAL: I can __________________________________________________________________________ ______________________________________________________________________________________________ MATTER AND ITS PROPERTIES What is a _____________________________? • A ________________ or ______________ associated with a particular type of matter. • Properties that matter possess can be placed into ____________ groups: • PHYSICAL Properties – those characteristics that can_____________________________________ ________________________________________________________________________________ Examples - _____________________________________________________________________________ _____________________________________________________________________________ _________________________________ – properties which describe ______________________________ _______________________________________________________________________________________ Examples - ______________________________________________________________________________ ______________________________________________________________________________ The SUBMICROSOPIC VIEW, SCIENTIFIC MODELS and INDIRECT EVIDENCE Much of science deals with the MACROSCOPIC and MICROSCOPIC world. Chemistry also deals with the __________________________________ world – those things that _______________ _______________________________________________________________________________________________ • • Since the submicroscopic world cannot be seen, our understanding of it is largely based on ____________ __________________________. Scientific models are _______________________________ that helps us understand and explain that which cannot be seen. Scientific Models are based on __________________________evidence. ______________________________________ is information gathered from _______________________ that _____________________ a particular idea or explanation of a natural phenomenon. o For example, much of what has been learned about atoms has result from how substances behave when _________________________________________________________________________ etc. SAMPLE PROBLEM - Describe the QUALITATIVE and QUANTITATIVE expressions in the following: • Substance #1 contains 10.2 grams of Calcium, 5.4 grams of Sulfur and 10.5 grams of Oxygen. Quantitative ______________________________________________________________________ Qualitative _______________________________________________________________________ • Substance #2 contains 45.5% Oxygen and 54.5 % Carbon. Quantitative ______________________________________________________________________ Qualitative _______________________________________________________________________ SOME WAYS TO CLASSIFY SUBSTANCES • • Substances can also be classified as either _________________________ or ________________________. A _____________________________ contains _________________________________________[element]. example _______________ – only contains Cu atoms or one kind of ______________________________ [compound] example _____________________ – only contains H2O molecules. • A _____________________ contains _________________________________________________________ with each other [elements or compounds]. PROPERTIES OF PURE SUBSTANCES • • • Made of only _____________________ of atom or molecule. Compounds ___________________________________________________ of the elements they are made up from!! Components are _______________________________! PROPERTIES OF MIXTURES • • • Can be any _____________________________________________________________________________. The individual components in the mixture ____________________________________________________. Usually ___________________________________ into the various components in the mixture. PRACTICE PROBLEM - CLASSIFY the following as PURE SUBSTANCES [label as element or compound] or MIXTURES. • Aluminum • Water • Table Salt • Gasoline • Sugar • A cake • Kool-Aid • Mouthwash • 14 Karat Gold • Blood • Baking Soda • Carbon Dioxide • Baking Powder • Soil • Milk
