Quick Writes will not be grade for points but for participation and honesty.

1. You are allowed to use your brain, any notes, labs or worksheets we have done in class.

2. You may not use your textbook or interactive reader.

3. You will have 10 minutes to complete as many questions as possible.

4. With a colored pencil, you will grade your own.

In Charge of Leading Discussion1. Log into Learning Point2. Daily Assignments3. This Week4. Open “Power Notes: Elements,

Compounds and Mixtures” slide share

5. Use your abbreviation skills6. R & R – Pgs 1 & 2

Elements are pure substances made of only one kind of atom.

1. As we have learned, atoms are tiny structures found in all matter.

2. Most substances contain many different atoms.

3. It is how those atoms are arranged that determine whether you have an element, compound or mixture.

Page 6: Power Notes  Elements, Compounds and Mixtures- Day 2

1. One kind of atom2. Pure (because all particles are the

same)

3. Smallest particle to retain identity of the element

4. Separated only in nuclear reactions

Page 7: Power Notes  Elements, Compounds and Mixtures- Day 2

Particles look like:

Every atom looks exactly

the same w/ the same number of

protons

Oxygen

Hydrogen

Example:

Your Example?

Aluminum: Every atom of

aluminum in this can is exactly

the same

Page 9: Power Notes  Elements, Compounds and Mixtures- Day 2

1. Two or more kinds of atoms chemically bonded

2. Pure (because all particles are the same)

3. Smallest particle to retain the identity of the compound (SET RATIO of particles)

4. Separated or rearranged in chemical reactions CO

Page 10: Power Notes  Elements, Compounds and Mixtures- Day 2

Particles look like:

Every compound looks

exactly the same w/ the

same set ratio

Carbon Dioxide – CO2

Sodium Chloride - NaCl

Page 11: Power Notes  Elements, Compounds and Mixtures- Day 2

Example:

Your Example?

Salt: Every molecule of the compound NaCl is exactly the

same

Page 12: Power Notes  Elements, Compounds and Mixtures- Day 2

1. Two or more elements and/or compounds blended together physically

2. Not pure (because all the particles are not the same)

3. Separation through distillation, magnetic, evaporation, density, or particle size

4. No set ratio

Page 13: Power Notes  Elements, Compounds and Mixtures- Day 2

Particles look like:

Each particle keeps its own

identity….they are just “blended”

together

Mixture #1

Mixture #2

Page 14: Power Notes  Elements, Compounds and Mixtures- Day 2

Examples:

Your Examples?

Heterogeneous: Different components are easy to see in

this type of blending

Homogeneous: Different components are difficult to see

because they are evenly distributed

Page 15: Power Notes  Elements, Compounds and Mixtures- Day 2

1. Based on your notes, LABEL the illustrations as Elements, Compounds or Mixtures

2. Then, Write the letters A, B, C, D or E from the pictures to match their description.

3. Classify the pictures as(CROSS OUT MOLECULE)

• ATOM• COMPOUND• ELEMENT

Page 17: Power Notes  Elements, Compounds and Mixtures- Day 2

Compound

Page 18: Power Notes  Elements, Compounds and Mixtures- Day 2
Page 19: Power Notes  Elements, Compounds and Mixtures- Day 2

Mixture

Page 20: Power Notes  Elements, Compounds and Mixtures- Day 2

1. A solution is a mixture where all the components blend together to look like one substance.

2. A solution is a homogeneous mixture that appears to be a single substance.

3. The solution is composed of particles of two or more substances that are distributed evenly among each other and have the same appearance and properties throughout.

Page 21: Power Notes  Elements, Compounds and Mixtures- Day 2

1. In solutions, the SOLUTE is the substance that is being dissolved and usually is the smaller quantity in the mixture.

2. The SOLVENT is the substance in which the solute is dissolved and usually is the larger quantity in the mixture.

3. It is the SOLVENT that is doing the dissolving.4. Go to page 144-145 in your textbook: • A) Copy example in Book• B) Give your own example – Groups can have

the same example

Page 22: Power Notes  Elements, Compounds and Mixtures- Day 2

Topic: Solutions (next 5 slides)

NameDatePeriod

Homogeneous • 2 or more things evenly blended and disappear into each other

Solute • Smaller quantity by %

Solvent • Larger quantity by %

Solution • Homogeneous mixture

Examples 1) Dish soap

2) (your example)

Page 23: Power Notes  Elements, Compounds and Mixtures- Day 2

Heterogeneous • 2 or more things put together (blended) but still can be individually seen

• No set Ratio

Example 1) Salad, Pizza, Trail Mix, Hamburger, Taco

2) (your example)

Page 24: Power Notes  Elements, Compounds and Mixtures- Day 2

Saturation Level

What does this mean?

What does this look like? (color)

Unsaturated

Saturated

Supersaturated

•Mixture contains more solvent than solute

•Able to dissolve more solute

•Mixture contains the % of solute completely dissolved by solvent

•Not able to dissolve more solute•Mixture contains the % of solute unable to be dissolved by the % of solvent at the given temp.High temp usually = higher

solubility

Page 25: Power Notes  Elements, Compounds and Mixtures- Day 2

Have you ever put sugar put into lemonade and see the grains of sugar sink to the bottom and not dissolve?

This is because the lemonade (solution) is supersaturated. In other words, there is not enough water (solvent) to completely dissolve the sugar (solute).

Temperature and Pressure can affect saturation levels.

1. We now know the definition of Element, Compounds & Mixtures

2. What do their particles look like?
