Learning Goal: • I can describe predict properties of • elements and compounds using trends of the • periodic table (e.g., metals, non-metals, • bonding – ionic/covalent). Homework: Chemistry unit test, stamp sheet and notebooks due 11/ 27 Daily Question: What is matter? Activities/Assignments: Grade Elements Quizzes (5th hour only!) Discuss Grades/Work on Notebooks Matter Notes (6th hour only!)

  2. Update Table of Contents TABLE OF CONTENTS

  3. Chemical Change • a change in which a substance becomes another substance having different properties • a change that is not reversible using ordinary physical means • Changes that usually cause heat, sound, light, odor, fizzing/foaming, color changes You usually need more than one of the above characteristics to be considered a chemical change! • Examples combining sulfuric acid and sugar burning a piece of wood soured milk

  4. Chemical or Physical Change? • Bending a Paper Clip • Baking a cake • The sublimation of carbon dioxide • Crushing an aluminum can • Vinegar and baking soda combining to create salt and water Physical Change Chemical Change Physical Change Physical Change Chemical Change

  5. Mass vs. Weight Mass • a measure of how much matter an object is made of • does not change, regardless of where something or someone is Weight • the force of gravity on an object • equal to the mass of the body times the local acceleration of gravity Why do you think the person’s weight is less on the moon? Mass = 59 kg Mass = 59 kg Weight = 579 N Weight = 96 N http://www.exploratorium.edu/ronh/weight/index.html

  6. 5 Physical States of Matter • Bose-Einstein • Solid • Liquid • Gas • Plasma (Newest State)

  7. Bose-Einstein Condensate • Exist at extremely cold temperatures (around absolute zero or -460 oF) • Particles are super unexcited • Particles lock or “clump” together so firmly that they move as a single unit • Definite shape and volume (?)

  8. Solid • Particles are tightly compact • Particles vibrate without the ability to move freely • Definite shape and volume • Solid Animation

  9. Liquid • Particles are tightly compact, but able to move around close to each other • No definite shape, but definite volume • Liquid Animation

  10. Gas • Particles can easily spread out or move close together • Particle move freely and with a lot of energy • No definite shape or volume • Gas Simulation

  11. Plasma • Exist at extremely high temperatures (several million degrees Celsius) • Particles are broken apart • Particles move freely and with extremely high energy • This form is not too common on Earth, however it is the most common form of matter in the universe • No definite shape or volume (?) • Examples: Florescent and neon lights, lightning, aurora borealis Why do you think this is the most common form/state of matter in the universe? - + + + - -

  12. Energy and the States of Matter • The physical states of matter result from the amount of energy the particles composing the matter have. Basically, more energy means more movement for the particles and less energy means less movement. • Energy/Temperature and Matter Simulations • PhET • BEC: Temperature and Absolute Zero If you were to compare an ice cube and the steam created from boiling water, which would you think has more energy?

  13. States of Matter Continuum What about this continuum could be considered a little misleading? Taken from: http://www.chem4kids.com/files/matter_becondensate.html

  21. Density • a measure of the amount of matter present in a given volume of a substance • typically expressed in the following units: • grams per cubic centimeter (g/cm3) for solids • grams per milliliter (g/ml) for liquids • does not depend on how much of a substance you have (intrinsic property) – in other words, the density of a gold bar would be the same as the density of a gold flake • can change as temperature and pressure change Which do you think is more dense? Why?

  22. Layering Liquids • Using a test-tube and the eyedroppers, try to layer the four different • colored liquids so that the colors don’t mix and show distinct layers. • Hold the test-tube in your hand at a 45 degree angle. • Using the eyedropper from one of the colors, slowly place the • liquid into the test-tube. • Repeat step two using the other three liquids until you get them • layered. Record the order of the colors. • If you don’t get clear separation of the colors, you should empty the • contents of the test tube down the drain and start again. These steps • may need to be repeated several times until you discover the correct • order of the colors. • *Placing white paper behind the straws will help you • see the divisions

  23. Layering Liquids - Discussion • Were you capable of layering the four liquids? If so, what was the correct order from the bottom up? • What difficulties did you experience when performing this activity? • Why do you think the liquids created layers when putting them in the test tube in the correct order? • Because these liquids are miscible, or partially miscible, they did not really create distinct layers. What do you think it means to be miscible?

  26. Calculating Density • Density can be calculated by dividing the mass of an object by its volume Sample Problem Timothy found a solid metal block that has a mass of 100 grams and a volume of 25 cm3. What would be the density of the block? D = m V 4 grams cm3 100 grams D = = 25 cm3

  27. Practice Problems • Find the density of a substance with a mass of 27 g and a volume of 7 cm3. • 2. A block of maple has a mass of 20 grams and a volume of 26.5 cm3. What is the density of the block? D = m V 3.86 grams cm3 27 g D = = 7 cm3 0.75 grams cm3 20 grams D = m V D = = 26.5 cm3

  28. . m = D V The Density Triangle D = m V m V = m D . D V

  30. Mixture Notes

  31. Solvent - Solute - Solution Solvent Part of the solution that is present in largest amount and dissolves a solute What liquid is called the “universal solvent”? WATER

  32. Solute Part of solution present in lesser amount and dissolved by solvent

  33. Solution A well mixed mixture containing a solvent and at least one solute that has the same properties throughout.

  34. Properties of Matter –

  35. Physical Property Characteristic of a pure substance that can be observed WITHOUT changing it into another substance.

  36. Chemical Property A characteristic of a pure substance that describes its ability to change into a DIFFERENT substance.

  37. Mixture Made of two or more substances- elements, compounds or both- that are together in the same place but are not chemically combined.

  38. Heterogeneous Mixture You can see the different parts

  39. Homogeneous Mixture So evenly mixed that you can’t see the different parts
