2. What is Chemistry? chemistry is....
The study of matter and its changes.

3. What is matter?
Matter is anything that has mass and takes up space (volume).
11/27/2018

4. Mass and Volume Mass : Amount of matter in an object
Measured in grams using a balance
Volume: amount of space an object takes up
Measured in cm3 or mL
Using a meter stick or graduated cylinder.

5. Identifying Matter What am I? I’m over 6 feet tall
Bigger than a bread box
Shiny and dull
Conduct electricity
All of these things help describe matter. One of the best ways to describe matter is…………..

6. Density

7. Which picture was more dense?
Why?
Definition of density
Mass per given unit of volume

8. Annotate Mass per given unit of volume Break down the definition
Vocab words?
Mass- amount of matter in an object
Volume- amount of space object occupies
New definition?

9. It means…
How much stuff is in a given space

10. Equation
D=M / V
D= density
M= mass
V= volume

11. Make it easy… M V D

12. What do you think??? What do you think the units of density will be?
M (units?) / V (units?)
Do they cancel?
g/ml or g/cm3

13. How would you……????
Find the density of this? What equipment would you use?

14. How would you…..?
Calculate the density of ……

15. Just kidding… I meant a …

16. What equipment would you use?

17. Which is right?
A B

18. Displacement Stick your thumb into clay. What did you leave?
What is it a model of?
How can you figure out how much space your thumb was occupying?
Displacement : how much an object pushes another away. WE can use the displacement of water in a graduated cylinder to figure our the volume of and object that is irregular.

19. Think it through Can with liquid 350 g Can alone 50 g Volume of can
You are to determine the density of the liquid in a Monster drink. Here is the data you know:
Material
Measurement

350 g
Can alone
50 g
Volume of can
150 ml
Density
???????

20. Think it through Material Measurement Rock 50g Volume water before
100ml

???????

21. Keep thinking….
If the density of water is 1 g/ml will the monster drink sink or float when placed in water?

22. Label from 1-5 most to least dense

23. Practice
Worksheets

24. Apply
Could you prove that Ms. T is more dense then a guest appearance?
Here are your tools 1 kg = 2.2 lbs
Write a procedure

25. Have fun!!!

26. Classifying Matter Are water and kool-aid the same? Why? Why not?
How about metal and air?
Why? Why not?
Matter needs categories or a classification system.

27. Classification of Matter
11/27/2018

28. Pure Substances
Pure substances are subdivided into two categories: elements and compounds.
11/27/2018

29. Elements
An element is a substance that cannot be separated into simpler substances by chemical reactions. In the periodic table, there are over 100 of these elements. Most of them can be found naturally on Earth. Others are produced synthetically by nuclear reactions.
11/27/2018

30. Describe what you see

31. The Periodic Table Period Group or Family Group or family Period
11/27/2018

32. Symbols of Elements Elements are indicated by symbols.
The first letter of the symbol of an element is always capitalized.
The second letter is never capitalized.
Examples: Silver = Ag, Carbon= C, Sodium = Na, Helium = He, Phosphorus = P
11/27/2018

33. Compounds
A compound is a substance that is composed of two or more elements chemically held together in fixed proportions.
A formula for a compound identifies the number and kind of elements in a compound and the proportion in which they are found.
Examples: H2O, H2O2, C6H12O6
11/27/2018

34. Examples of compounds
11/27/2018

35. The number at the bottom of a symbol is called a subscript.
The subscript at the bottom of symbol indicates the number of atoms. Atoms are the building block of matter.
How many Ca? O? Cl? In bleach….

36. Mixtures Lab
Enjoy!

37. Mixtures
A mixture is a combination of two or more substances in which each substances’ identity is retained.
The mixture doesn’t have a uniform composition
The substances in a mixture can be separated by physical means.
What does the mean in your own words?
11/27/2018

38. Homogeneous Mixtures
Homogeneous mixtures are solutions which have uniform composition and appearance throughout. A solution may be gaseous (air), solid (brass) or liquid ( seawater). An alloy is a solution of two metals.
Solutions have two parts:
Solute-the substance that is dissolved; present in smaller amount
Solvent-the substance that does the dissolving; present in the larger amount
11/27/2018

39. Solute vs Solvent- compare and contrast……

40. Homogeneous
Solution?
Why?
11/27/2018

41. Heterogeneous Mixtures
Heterogeneous mixtures are mixtures that do not have uniform composition and appearance throughout. The individual components which make up the mixture remain physically separated and can be seen as separate components.
In your own words???????
There are two types of heterogeneous mixtures: colloids and suspensions
11/27/2018

42. Heterogeneous Mixture
The constituents of the mixture retain their identity and may be separated by physical means.
11/27/2018

43. Examples of Mixtures

44. Characteristics of Mixtures
Type of Mixture
Size of particles

Very small No
None
Colloid

Suspension

45. Tyndall Effect
In the beaker on the left, the beam of light is visible. This is a positive Tyndall effect. The particles in the beaker are large enough to scatter the light.
The beaker on the right exhibits a negative Tyndall effect. You cannot see the beam of light. There are no particles in the mixture to scatter the beam of light.

46. Who is who? Why? DEEDS!

47. Separating Mixtures Four ways to separate a mixture: Filtration
Distillation
Chromatography
Crystallization
11/27/2018

48. BP oil spill Bp Reading for meaning. Any suggestions????? Let’s try.
BP lab

49. Filtration
Filtration separates a solid from liquid through the use of a porous material as a filter. Paper, charcoal, or sand can serve as a filter. The liquid can pass through but not the solid.
11/27/2018

50. Distillation
Distillation is a method used to separate a mixture of liquids according to their boiling points.
11/27/2018

51. Chromatography
Chromatography (demo) is a method for analyzing complex mixtures (such as ink) by separating them into the chemicals from which they are made.
11/27/2018

52. Crystallization
Crystallization refers to the formation of solid crystals from a homogeneous solution.  It is essentially a solid-liquid separation technique

53. Is that water safe?
Time to see if your water is safe!

54. States of Matter and Phase Changes

55. 4 states of matter
Match words with pictures: Solid, gas, liquid,plasma

56. Write…Chalk talk… How did you decide which was which?
What did you notice about the difference between your choices?
What makes the particles stay close or move apart?

57. Solids are… Tightly packed particles Definite volume (lxwxh)
Definite shape
Density- displacement
Vibration of particles

58. Liquids are… Loosely packed Definite volume (graduated cylinder)
Definite shape (container)
Density
Slip and slide of particles

59. Gases are….. No organization of particles
No definite volume (must be contained)
No definite shape- can be contained
Density- if in a container minus mass of container
Random motion

60. Plasmas are….. No organization of particles No definite volume
No definite shape
Density- can’t catch it
HIGH ENERGY!!!! Random motion

61. It’s all about ENERGY!
All states of matter can change due to changes in

62. Compare and contrast
Solid energy
Gas energy
Liquid energy

63. Changes
If I am moving slow and start moving faster am I increasing or decreasing energy?
Draw a diagram that puts states of matter in order from low to high energy

64. Place these words in between states of matter where the process would occur
Boiling
Evaporation/vaporization
Melting
Sublimation
Freezing
Deposition
condensation

65. Check yourself

66. Increasing energy Melting- s to l
Evaporization/boiling/vaporization- l to g
Sublimation- s to g
Sublimation s to g

67. Decreasing energy Condensation- g to l Freezing- l to s Deposition
Deposition g to s

68. organize Draw a mind map organizing these ideas
States of matter condensation gain E
Solid melting lose E
Liquid freezing
Gas sublimation
Gaining energy deposition
Losing energy evaporation

69. The end! Good Luck on your test!
