5. © 2012 Pearson Education, Inc. Chemistry In this science we study matter, its properties, and its behavior.

6. © 2012 Pearson Education, Inc. Matter We define matter as anything that has mass and takes up space.

7. © 2012 Pearson Education, Inc. Matter- is made of… Atoms are the building blocks of matter. Each element is made of the same kind of atom. A compound is made of two or more different kinds of elements.

8. © 2012 Pearson Education, Inc. How do we Classify Matter?

18. © 2012 Pearson Education, Inc. Properties and Changes of Matter

19. © 2012 Pearson Education, Inc. Types of Properties Physical Properties… –Can be observed without changing a substance into another substance. ◦ Boiling point, density, mass, volume, etc. Chemical Properties… –Can only be observed when a substance is changed into another substance. ◦ Flammability, corrosiveness, reactivity with acid, etc.

20. © 2012 Pearson Education, Inc. Types of Properties Intensive Properties… –Are independent of the amount of the substance that is present. ◦ Density, boiling point, color, etc. Extensive Properties… –Depend upon the amount of the substance present. ◦ Mass, volume, energy, etc.

21. © 2012 Pearson Education, Inc. Types of Changes Physical Changes –These are changes in matter that do not change the composition of a substance. ◦ Changes of state, temperature, volume, etc. Chemical Changes –Chemical changes result in new substances. ◦ Combustion, oxidation, decomposition, etc.

22. © 2012 Pearson Education, Inc. Separation of Mixtures

23. © 2012 Pearson Education, Inc. Filtration In filtration, solid substances are separated from liquids and solutions.

24. © 2012 Pearson Education, Inc. Distillation Distillation uses differences in the boiling points of substances to separate a homogeneous mixture into its components.

25. © 2012 Pearson Education, Inc. Chromatography This technique separates substances on the basis of differences in solubility in a solvent.

26. List some physical and chemical properties of these substances If a mixture… how can we separate?

27. Bubbles of Boiling Water a.What’s inside the bubbles of boiling water? b.Is boiling chemical or physical change?

28. Lab Safety What do you do if you –Spill acid on table? On self? –Spill base on table? On self? Where do you put broken glass? Why? If you feel faint, what do you do? If you cut yourself- what do you do? If you burn yourself- what do you do? If you accidently swallow a chemical? If you splash chemical in eye- what do you do? If a beaker of flammable liquid catches fire… what do you do? If your sleeve catches fire- what do you do?

29. Review laboratory equipment
