Safety contract • Take home, get signatures and return it tomorrow! We’ll
discuss it tomorrow and take a safety test
![Page 12: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/12.jpg)
Keys to success in Chemistry
• Get a 3 ring binder! (keep everything organized)• Pay attention to the skills we cover & review daily!• DO NOT MISS class. (Makeup work quickly)• READ YOUR TEXT!• Do more work than just the assigned
problems.
• STOP IN IF YOU DON’T GET IT!!!• Bring a sci. calculator & your book/chromebook daily• Always do your homework!!! (Plan on 30-45 min a night!)
• Show all your work at all times
• DO THE PDP’S AS I SUGGEST!
![Page 13: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/13.jpg)
Keys to success in Chemistry
• Know our “clear learning goal” for the day.
![Page 14: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/14.jpg)
Grading
• Check Powerschool frequently!• I go by total points. Everything is worth
point, tests have many more points. But don’t overlook the simple day to day things. Complete lab write ups and daily work as these are important too.

5 evidences of chemical change. • Release of energy: heat or light. Could be a gain of
energy too. (exothermic or endothermic)• Color change• Precipitate or solid being formed.• Gas• New odor• Is there an acronym we can make to remember these?
![Page 24: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/24.jpg)
Definition of chemistry.
• The study of the structure, properties and composition of
substances and the changes that substances undergo
![Page 25: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/25.jpg)
Why study chemistry?
• Chemistry is NOTa study of facts. It is an ongoing human activity.
• What things are you involved in, or see, that do NOT involve chemistry?
![Page 26: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/26.jpg)
Chemists look at composition and
behavior of matter. They create
new products or make
existing products better

Law of Conservation of Mass
• Mass can not be created or destroyed in ordinary (not nuclear) chemical reactions or physical change
• All the mass can be accounted for.– Burning of wood results in products that
appear to have less mass as ash; where is the rest?
![Page 78: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/78.jpg)
In a chemcial reaction
• products have NEW PROPERTIES because the ratio and arrangement of atoms is different!
• We draw an arrow from reactants to products
R P
• The exothermic reaction when Magnesium metal burns can be shown by this reaction: Mg + O2 MgO + Heat

What is Matter?
• Matter is anything that takes up space and has mass.
• Mass- amount of material or “stuff” in an object
• Weight is due to gravity, and changes from location to location; mass is always constant.
![Page 116: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/116.jpg)
Classification (sub classification)
• Element (metal, nonmetal, metalloid)• Compound (has formula. . . Constant proportion of
elements)• Mixture * (heterogeneous or homogeneous)
• *special mixtures for construction are called composites
![Page 117: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/117.jpg)
Types of Matter• Substance- a particular kind of matter
- pure; is uniform (all the same) and has a definite composition (examples are elements & compounds)
• Mixture- more than one kind of matter; has a variable composition
![Page 118: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/118.jpg)
States or Phases of matter• Solid- matter that can not flow (definite
shape) and has definite volume.• Liquid- definite volume but takes the
shape of its container (flows).• Gas- a substance without definite
volume or shape and can flow.• Vapor- a substance that is currently a
gas, but normally is a liquid or solid at room temperature. (water vapor?)
![Page 119: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/119.jpg)

Mixtures• Physical blend of at least two substances; variable
composition• Heterogeneous- mixture is not uniform in composition• Chocolate chip cookie, gravel, soil.• Homogeneous- same composition throughout; called
“solutions”• Kool-aid, air, salt water• Every part keeps its own properties. These look
uniform, but are NOT always put together in the same ratios.
• Alloys are solutions.
![Page 122: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/122.jpg)
Solutions
• Homogeneous mixture– We haven’t changed the individual components.
• Mixed molecule by molecule• Can occur between any state of
matter– gas in gas; liquid in gas; gas in liquid;
solid in liquid; solid in solid (alloys), etc.
![Page 123: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/123.jpg)
Solutions
• Like all mixtures, they keep the properties of the components.
• Some can be separated easily by physical means: rocks and marbles, iron filings and sulfur
![Page 124: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/124.jpg)
Phases A “system” with uniform composition and
properties are a phase. Pure substances have one phase, homogeneous mixture have a single phase. A heterogeneous mixture has 2 or more phases. Think of ice cream sundaes.
Phases are “Parts you can see”
![Page 125: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/125.jpg)
Substances• Elements- simplest kind of matter• cannot be broken down any simpler• all one kind of atom.• Compounds are substances that can
be broken down only by chemical methods
• When broken down, the pieces have completely different properties than the original compound. They HAVE FORMULAS
![Page 126: Unit 1 lectures s2015](https://reader038.fdocuments.in/reader038/viewer/2022102718/55d21226bb61eb5e488b4687/html5/thumbnails/126.jpg)
