Types of Matter Miscellaneous Properties & Changes Types Of Mixtures Separation Techniques
This theory says that all matter is made up of tiny particles in constant motion
. Kinetic Theory of Matter
In elements, these are all the same kind
Atoms
All mater can be divided into these two classes
Substances And Mixtures
VIDEO DOUBLE 1.Which shows a substance? 2.What type of substance?
VIDEO DOUBLE This represents a substance. What type? Compound
This represents an element.
This represents an element.
This is the term for a homogeneous mixture.
Solution
This heterogeneous mixture does not separate.
This heterogeneous mixture does not separate. Colloid
This mixture will separate into layers if allowed to stand.
Suspension This mixture will separate into layers if allowed to stand.
This term means that one substance will dissolve in another.
Miscible
This term is used to describe something that is not uniform.
Heterogeneous
These are characteristics of matter that can be observed WITHOUT changing the substance.
Physical Properties Examples: conductivity, boiling point, color, texture,
This law says that when a chemical change takes place matter is not created or destroyed.
Law of Conservation of Mass
Combustion is an example of what type of change?
Chemical Change When something burns its chemical composition is being changed into something else.
What kind of change occurs when ice melts?
Physical Change
DOUBLE Neon is an inert gas. 1.What kind of characteristic is this. 2. What does inert mean?
1. Chemical Property 2. Does not react with other substances
This type of separation usually sorts particles based on size. Larger particles can not pass through.
This type of separation usually sorts particles based on size. Filtration
Distillation uses this physical property to separate mixtures.
Boiling Point
This type of separation uses the physical properties of iron to separate it from other substances.
This type of separation uses the physical properties of iron to separate if from other substances. Magnets
Centrifugation uses this physical property to separate mixtures under high G forces.
Centrifugation uses this physical property to separate mixtures under high Gs. Density
In this separation technique a mixture is separated as it interacts with the mobile and stationary phases.
Chromatography
This is the result of two or more elements becoming chemically bonded.
Compound
This is anything that has mass and takes up space.
Matter
Smog in air is an example of this type of heterogeneous mixture.
colloid
What is the density of a 10 g sample of rock with a volume of 5 cm 3 ?
D = m/v = 10g / 5 cm 3 = 2 g/cm 3
A gold bar has a mass of 12.5 kg. What is its volume if the density of pure gold is 19.3 g/cm 3 ?
A gold bar has a mass of 14,048 kg. What is its volume if the density of pure gold is 19.3 g/cm 3 ? D = m/V V = m/D V = 14,048 g / 19.3 g/cm 3 = cm 3
