Question: What are the two types of pure substances?

6. Composition of Matter
Matter is any thing that has mass and takes up space (volume).
Examples: air, book, water, etc.
All matter is made of atoms
Matter can be made of a pure substance or a mixture of substances.

7. Pure Substances
Pure substance is a type off matter with a fixed composition.
Pure substance can be either an element or a compound
Examples: Elements: helium, aluminum,
Compounds: water and salt

8. Element is a substance in which all the atoms are the same.
About 90 elements are found on Earth
More than 20 others have been made in laboratories and are very unstable.

9. Compound is a substance with two or more elements that are combined in a fixed proportion
Compounds are chemically bonded and can not be physically separated.
Compounds are new substances and have different properties then the elements that form the new substance.
Example: Table salt (sodium chloride)
Sodium & water NaCl

10. Mixtures
Mixture is made of two or more different elements or compounds that physically combine.
Mixture is NOT a pure substance
Substances within a mixture can be physically separated.
Substances in a mixture retain their individual properties.
Example: salt water, air, soil

11. Types of mixtures
Heterogeneous mixture a mixture in which different materials can be identified easily. Mixture is NOT uniform, materials are unevenly mixed.
Example: pizza granite, salad

12. Homogeneous mixture a mixture that contains two or more substances blended evenly throughout. Mixture is uniform, can not see the different substances.
Examples: soda, vinegar, cake batter
Solution is a homogeneous mixture of particles so small that they cannot be seen with a microscope and that will never settle to the bottom of their container.

13. Colloid a type of mixture with particles that are larger than those in solutions but not heavy enough to settle out.
Examples: milk, paint, fog, smoke
Solutions vs colloid
Tyndall effect the scattering of light by particles in a colloid.

14. Suspension a heterogeneous mixture containing solid particles in a liquid which will settle out over time.
Example: Italian dressing, muddy water, dust in air

15. Comparing and contrasting types of mixtures
Description
Solutions
Colloids
Suspensions
Settle upon standing No
Yes
Separate using filter paper?
Particle size
0.1 – 1 nm
1 – 100 nm
>100 nm
Scatter light

Question: What is the law of conservation of mass?

23. Properties and changes of matter
Physical property a feature or characteristic that describes an object or substance.
Describing Appearance –
color, shape, state of matter
measurement – volume, temperature, density, length
Describing behavior
Magnetic, viscosity
Separate materials
Magnetism and filtration (sifting)

24. Example: melting, boiling, freezing, evaporating
Physical change a change in size, shape, or state of matter. Identity of substance remains the same
Example: melting, boiling, freezing, evaporating
Separating with physical change
Distillation is the process of separating substances in a mixture by evaporating a liquid and recondensing it vapor
Separating substances based on boiling point

25. Chemical property a characteristic of a substance that indicates whether it can undergo a certain chemical change.
Example: flammability, toxicity, corrosive

26. Chemical change of one substance to another.
Detecting a chemical change
Release of energy in the form of heat, light, sound
Endothermic absorption of energy in form of heat (object will feel cold)
Exothermic release of energy in form of heat (object will feel warm)
Gas being released and precipitate forming

27. Conservation of mass
Law of conservation of mass: the mass of all substances that are present before a chemical change equals the mass of all the substances that remain after the change.
Mass remains constant
