Ag Chemistry

Front 1

Chemistry:

Back 1

is the study of composition structure and reactions of matter.

Front 2

Matter:

Back 2

has mass and occupies space in three forms solid liquid or gas.

Front 3

Composition:

Back 3

of what is substance composed (elements and Compounds)

Front 4

Element:

Back 4

is a pure substance containing one type of atom

Front 5

Compounds:

Back 5

is a pure substance containing two or more elements in a fixed proportions.
§ Hydrogen Chloride (Compound)= Hydrogen (Element) + Chlorine (Element)

Front 6

Structure:

Back 6

specific arrangement of elements in a substance

Front 7

Reactions:

Back 7

"something is being changed" Results in change in composition and or structure of compounds
§ General Formula for chemical Reactions: Reaction Yield Products

□ Example: HCL + Ca(Co3)2 Yield CaCl2 + Co2 +h20 we will make this in the lab.

What is Matter?

Back 11

1.1 Anything that has mass and occupies space

Front 12

○ Mass:

Back 12

the amount of matter in an object

Front 13

○ Weight:

Back 13

the gravitational force acting on an object

Front 14

Physical Properties:of Matter:

Back 14

are properties that can be measured without try to change the composition of the matter being studied.

Front 15

Chemical Properties: of Matter:

Back 15

are properties of matter that are demonstrated when one attempts to change it into a new substance.

Front 16

Physical Changes:

Back 16

i. Physical Changes: are changes of matter that take place but do not change the composition of the matter.

Front 17

Chemical Changes:

Back 17

are changes in the composition of matter.

Front 18

Describe matter:

Back 18

matter is anything that occupies space and has mass and it is made up of particles to small to see.

Front 19

Molecule:

Back 19

is the smallest particle of a pure substance and capable of a stable existence.

Front 20

Atoms:

Back 20

make up molecules and limit the chemical subdivision for matter.

Front 21

Diatomic Molecules:

Back 21

contain two atoms

Front 22

Homoatomic molecules:

Back 22

are molecules that only contain one type of atom

Front 23

Heteroatomic molecules:

Back 23

contain two or more types of atoms

Front 24

Triatomic Molecules:

Back 24

contain three or more atoms

Front 25

Polyatomic Molecules

Back 25

: molecules that contain more than three atoms.

Front 26

Heterogeneous: Matter

Back 26

a. with properties that are not the same throughout.(appears to the eye as two or more substances.

Front 27

Homogeneous: Matter

Back 27

b. Homogeneous: Matter with properties that are the same throughout. (appears to the eye as one substance)

Front 28

Solution:

Back 28

c. Solution: Homogeneous mixture of two or more substances

Front 29

Pure substance:

Back 29

d. Pure substance: matter that has a constant composition and fixed properties.

Front 30

Mixtures:

Back 30

e. Mixtures: matter that can be separated into two or more pure substances.

Front 31

Element

Back 31

f. Element: pure substances made up of Homoatomic molecules (one kind of atom is found)
You cannot further divide an element into any simpler pure substance but you can break compounds into simpler pure substances.

Front 32

Compound

Back 32

g. Compound: A pure substance made up of Heteroatomic molecules (more than one kind of atom is found)
