What is matter

What is matter?

A) An object that take up space and has mass

B) The color of the object

C) The mixtures

Answer A


States of matter

States of Matter

Solid Liquid

1. Has definite shape 1. Atoms move alittle

2. Has definite volume more freely

3. Atoms are packed tightly 2. Water

4.Particles vibrate 3. Atoms move

5. It is hard differently depending on khjj temperature.


States of matter1

States of Matter

Liquid

4. Takes the shape of a container

5. definite volume

Gas

1.Takes up whole volume

2. Particles get excited and move farther and farther

3. Definite shape

4. cannot see a gas 5.carbon dioxide


Physical and chemical properties

Physical and Chemical Properties

Physical Properties- Is without changing the makeup of a substance you can also observe or measure it. Examples: color, smell, freezing point, boiling point, and melting point.

Chemical Properties-Is when the properties of an object have a reaction. Examples: Hydrogen balloon, burning steel wool, alka seltzer, Zinc, Iodine reactions.

What is the difference between them?

The difference between them is that physical you check the shape, temperature,weight, etc.... With chemical you cannot observe checking the 5 senses .

Physical and chemical changes

Physical and Chemical Changes

Physical Change- Is a change that does not produce (make) a new substance. Example: stirring an egg, painting wood, cutting bread, water, glass breaking.

Chemical Change- Are changes that result in the productions of another substance. Example: burning paper, digesting food, baking a cake, fireworks, good car rusting.

What is the difference between them?

Physical Change does not make a new substance, but Chemical Change does .


Chemistry project

Atom

What is an Atom?

It is the smallest part of matter.

An Atom has 3 different parts

-Protron- positive charge

-Electron- negative charge

-Neutron- neutrally charged


Atom model

Atom model

electrons (-) proton(+) nucleus

neutron (O)


Chemistry project

Element

What is an Element?

is a pure substance that cannot be broken down into any simpler substances by chemical methods. Example: 1 2

carbon - element Dubnium - element 6 - atomic # 105 - atomic #

C - symbol Db - symbol

12.o11 - atomic mass 262 - atomic mass


Element

Element

Example: 3 4

Oxygen - element Nitrogen - element

8 - atomic # 7 - atomic #

O - symbol N - symbol

15.999 - atomic mass 14.007 - atomic mass

Example: 5

Aluminum - element

13 - atomic #

Al - symbol

26.982 - atomic mass


Compound

Compound

What is a Compound?

A thing that is composed of 2 or more separated elements.

Examples:Salt

Barite

Copper

Tin

Wood

Steel

Aluminum

Hematite

Plastic

Cotton


Periodic table

Periodic Table

What is a Periodic Table?

-The periodic table is a table of the chemical elements in which the elements are arranged by order of atomic number in such a way that the periodic properties of the elements are made clear.

How are they used?

They are used to quickly locate information of that certain element.

What is the pattern?

The arrangement of all elements are in order to increase atomic #.


Substance and mixtures

Substance and Mixtures

Substance- A material with a definite chemical composition.

Mixtures- A material with a definite physical composition.

What is the difference between them?

The difference between them is that with substance they cannot be broken down physically, also a mixture cannot be broken do chemically.


Heterogeneous and homogeneous

Heterogeneous and Homogeneous

What is the difference between them?

Heterogeneous and homogeneous refer to mixtures of materials in chemistry. The difference between heterogeneous and homogeneous mixtures is the degree at which the materials are mixed together.

Heterogeneous Ex: Homogeneous Ex:

- sand - blood

- salt - glass of juice

- tea - mixture of alcohol and water

- soda - hard wine

- milk - alcohol


Solutions

Solutions

What is a Solution?

A solution is a homogeneous mixture of one or more solutes dissolved in a solvent.

examples:

- salt in water - tea - sugar in coffee

- sugar in water - coffee

Solute- The substance that dissolves in a solvent to produce a homogeneous mixture

Solvent- The substance in which a solute dissolves to produce a homogeneous mixture


Examples

Examples

Solute examples- Solvent examples-

-chromium - salt

-iodine -water

-eggshells

-glue

-nail polish


Solubility

Solubility

What does Solubility mean?

The quantity of a particular substance that can dissolve in a particular solvent.
