Term
Law of conservation
A. State what it is
B. give an everyday example
C. Give one chemical reaction that illustrates it.
Definition
A. The total mass remains constant during a chemical change.
B. Burning wood
c.Heating up 5g of mercury oxide creates 4g of mercury and 1g of oxygen
C.
Term
Solids Liquids And gases
A. Describe th
E differences between the states of matter
Definition
A. Substances in solid form are identified by their rigidity; they maintain their Shapes when subjected to outside forces. Liquids and gases however are fluids; that is, they flow easily and change their shapes in response to slight outside forces.
B. solid:rock liquid: water gas: oxygen
Term
Properties of matter
A. Physical property
Definition
A. A characteristic that can be observed for a material without changing its chemical identity
Size
Shape
Weight
Term
Chemical property
Define it
Give three examples
Definition
A characteristic of a material involving its chemical change
Irons ability to react with oxygen to produce rust
Burning wood
Acid melting through metal
Term
Physical change
Definition
A change in the form of matter but not in its chemical identity
Chopping wood in half
Dissolving one material in another
Term
Chemical change
Definition
A change in which one or more kinds of matter are transformed into new matter or several new kinds of matter
The rusting of iron
The burning of wood
Term
Substances- describe the difference between pure and impure substances
A. Elements
Define:
Three examples
Definition
A substance that cannot be decomposed by any chemical reaction into simpler substances.
Iodine
Arsenic
Mercury
Term
Compounds
Define
3 Examples
Definition
A compound is a substance composed of two or more elements chemically combined.
CO
CO2
H2O
Term
Mixtures
Define
3 Examples
Definition
A mixture is a material that can be separated by physical means into two or more substances.
Milk
Air
Gasoline
Term
Describe the difference between heterogeneous and homogeneous mixtures.
Definition
A heterogeneous mixture is a mixture that consists of physically distinct parts, each with different properties.
A homogeneous mixture is a mixture that is uniform in its properties throughout given samples.
Term
Intensive Property
Define
2 Examples
Definition
Intensive properties do not depend on the amount of matter that is present. Examples of intensive properties include boiling point and density.
Term
Extensive property
Define
2 Examples
Definition
Extensive properties do depend on the amount of matter that is present. Examples of extensive properties include volume and mass.
Term
Chromotography
A. What is it
B. 3 different types
Definition
A. Chromatography is a group of similar separation techniques.
B. Gas Chromotagraphy: Separates mixtures on the basis of their distribution between a stationary liquid phase and a mobile gas phase. A chemically inert carrier gas.
Column Chromatography: liquid that is pumped thru a column filled with fine solid particles whose surfaces have been chemically treated.
Paper Chromatography: A technique for separating and identifying mixtures that are or can be colored, especially pigments.
Term
Paper chromatography applied
Definition
Paper chromatography can be used to separate color pigments, such as in the MnM experiment.
