1. Tuesday September 1st: Be ready to take notes/ you have a guided sheet
Matter Notes
What is Matter?
Identifying different types of matter
Separation Techniques

2. Matter
What is Matter?
Identifying Pure Substances, Mixtures, and Compounds
Separation Techniques
SOM

3. Learning Targets for Today:
I can define Matter (DOK 1)
I can define the Law of Conservation of Matter (DOK 1)
I can distinguish between and define examples of: solution, suspension, colloid, and pure substances (DOK 1 and 2)
I can identify and explain the states of matter in terms of volume and shape (DOK 1 and 3)
I can identify and explain the states of matter in terms of movement of particles (DOK 1 and 3) I can assess when to use the different separation techniques (distillation, crystallization, chromatography, and filtration) (DOK 3)
I can compare various forms of matter to place them their distinct categories based on composition and properties (DOK 2 and 3)

4. What is Matter? Anything that has mass and takes up space
Mass – the amount of matter that an object has
Volume-the amount of space an objects takes up

5. The law of Conservation of Matter
Matter cannot be created
nor destroyed

6. Law of Conservation of Matter
What does it mean?
During a chemical reaction what goes in, must come out, it is just rearranged.
If 5 grams of sodium reacts with 10 grams of sulfur, how much sodium sulfide is produced?
5 grams of Na + 10 grams of s = 15 grams of na2S
What is the amount of lithium chloride produced, if 9.9 grams of lithium reacts with 3.4 grams of chlorine?
9.9 grams of Li grams Cl = 13.3 grams of LiCl (13 grams)

7. States of Matter Matter occurs in four different states: Solid Liquid
Gas
Plasma

8. STATES OF MATTER

9. Kinetic energy Kinetic Energy (KE) – energy with motion
Kinetic Theory of matter – all matter is made of tiny constantly moving particles

10. solids Has a definite shape and a definite volume
Very tightly packed particles
Particles move very slowly
Expands only slightly when heated
Have Low kinetic energy

11. liquids Has definite volume, but no definite shape
Takes the shape of its container
Particles are slightly free, and move fairly fast
Almost incompressible particles
Tendency to expand when heated
Moderate kinetic energy

12. Gases No definite shape or volume Particles are spaced very far apart
Particles are free and very fast moving
Easily compressed (tanks of helium, nitrogen, etc)
Takes the shape and volume of it’s container
High kinetic energy

13. States of Matter

14. Plasma Super heated, ionized gas (negatively charged particles)
No definite shape or volume
Extremely high temperatures
Particles are spaced very far apart
Particles are very fast moving
Easily compressed
Extremely high kinetic energy

15. Different forms of matter
Pure substances
Elements and Compounds
Mixtures
Heterogeneous and Homogenous

16. Different forms of matter

17. Pure Substances Matter with a uniform composition
Matter that is always made up of the same ratio in a given order and cannot be separated by physical means

18. Substances: Elements and Compounds
the simplest form of matter
cannot be separated
building blocks for all other substances
two or more elements chemically combined
has a definite ratio
can be separated by only a chemical process
properties of a compound are different from the properties of the elements that make it

19. Compounds – do not retain the individual element’s properties
Properties of a compound are different from the properties of the elements that make it.
Example:
Sodium (Na) – solid at room temperature that reacts violently with water
Chlorine (Cl) – poisonous yellow-green gas at room temperature
Sodium Chloride (NaCl) – white crystalline water soluble solid used as a food additive

20. Mixtures

21. Mixtures Physical blend of two or more substances No definite ratio
Can be separated by physical means

22. Two different types of mixtures
heterogeneous
homogenous
Does not have a uniform composition
Different components of the mixture are usually easy to identify
Has a uniform composition
Different components of the mixture are not easily identified
solution

23. Solutions
Solutions are homogenous mixtures, because it is difficult to identify the individual components that make them up
Solutions are composed of:
Solutes – what is dissolved in the solution
Solvents – what dissolves the solute
Think of sweet tea – Sugar is the solute, because it is dissolved in the solvent, which is the tea.

24. Separation Techniques
Filtration
Distillation
Chromatography
Evaporation
Crystallization

25. Filtration Used to remove solids from liquids How coffee filters work

26. Distillation
Using the difference in boiling points to separate two different liquids from each other.
Distillation
What do you think is a common use for distillation?

27. Chromatography
Chromatography Separation technique to separate mixtures You may have seen this on CSI or any crime drama Abby uses it on NCIS! Can be used to separate proteins or dna

28. Evaporation A means of separating a solid out of a solution
Salt out of salt water
Evaporation

29. What are the sugar crystals, that he mentions at the end of the video?
Crystallization
A means of separating a solvent out of a super saturated solution
Crystallization
What are the sugar crystals, that he mentions at the end of the video?
