1. Chapter 1- Matter and Change
EQ: How is chemistry used to study the world around us?
Students will know how the atomic structure is related to an element’s position on the Periodic Table of Elements.
Bravo! – 15,000 kiloton atomic bomb!!!

2. Introduction Chemistry connects us to the world.
All we see, taste, & touch is matter.
Matter makes the world real.
Chemistry = study of matter: (properties, composition, how matter interacts).

3. Chemistry involved in many interesting jobs.
Making perfumes, colognes, cosmetics.
Crime scenes (forensics).
Preparing great tasting and safe foods.
Developing life-saving drugs.

4. Section 1-1 Chemistry is a physical science.
Chemical = substance with a definite composition.
Ex: water is always H2O.
Everything made of chemicals.

5. 6 Branches of Chemistry
Organic Chemistry- study of carbon containing compounds. Example: C6H12O6 (Glucose) Inorganic Chemistry- study of compounds that do not contain carbon. Example: H2O Water.

6. 6 Branches of Chemistry
Physical Chemistry- study of properties, changes, & relation of energy and matter.
Analytical chemistry- study of components & composition of materials.

7. 6 Branches of Chemistry Biochemistry- study of living things.
Ex: photosynthesis, fermentation
Theoretical Chemistry- study of math & computers to design/predict new stuff.

8. Types of Research Basic Research-how and why things work.
Applied Research- solve specific problem. Ex: depletion of the ozone layer.
Technological Development- application of science to solve problems. Ex: biodegradable materials

9. Section 1-2 Mass: amount of matter.
Matter: anything with mass & volume Ex: air, smoke, water .
Atom: smallest unit of element.
Element: made of one kind of atom.
Periodic Table contains 118 elements.
92 naturally occurring (found in nature)
Other 26 synthetically made.

10. Compound: 2+ elements chemically bonded.
Physical properties: measured without altering material. Ex: MP of ice

11. Physical Properties
Extensive Physical Properties: depend on the amount of matter. Ex: mass & length
Intensive Physical Properties- does NOT depend on amount of matter. Ex: MP, BP, FP, density, color, crystal shape

12. Physical change - does NOT result in change in identity
Physical change - does NOT result in change in identity. Ex: cutting wire, crushing a solid, gas expanding.
Changes in state(S <-> L <-> G)
Ex: melting, boiling, freezing.
Chemical Properties: undergo changes that alters identity. Ex: reactivity.

13. Chemical change or reaction (rxn); new substance made
Chemical change or reaction (rxn); new substance made. Ex: bread baking, nail rusting, moldy orange
Basic Chemical Formula
A + B  C
A & B are called reactants
 is read “yields” = “produces”
C is the product (s)

14. 4 states of matter Solids: definite shape &volume.
Liquids: definite volume; no definite shape.
Gases: no definite volume; no definite shape.
Plasma: gaseous system of charged particles.

15. Weight vs. Mass Weight: pull of gravity on object.
Mass: quantity of matter.
Astronauts in space experience weightless since gravity changes.
Ex: 120 lb person on earth would only weigh 20 lb on moon (1/6th gravity), but would still have a mass of 120 lb.

16. Law of conservation of mass: matter CANNOT be created nor destroyed.
Ex: burning wood, nuclear reactions
Law of conservation of energy : energy CANNOT be created nor destroyed, but can be converted. Ex: Kinetic & potential energy.

17. Classification of Matter
Mixture: 2+ kinds of matter; each retains identity & properties; can be separated physically.
2 types of mixtures
Homogeneous (solutions); uniform composition.
Ex: air, sugar in water, stainless steel.
Heterogeneous; not uniform.
Ex: granite, wood, blood.

18. Pure substances
Compound: made from atoms of 2+ elements that are chemically bonded.
Ex: water, salt, sucrose.
Cannot be separated physically.
Element: made of one pure substance that cannot be broken down.
Examples: gold, silver, hydrogen.

19. Chapter 1 SUTW Prompt
