Matter is everything that has mass and occupies space

Macroscopic properties and macroscopic properties

What can properties of matter be divided as

Macroscopic properties is anything that can be experienced by your senses

Microscopic properties is anything that cannot be experienced by your senses

-Strength of material                       -Thermal properties                     -Electric properties                     -Magnetic properties                      -Solubility                                     -Brittleness, ductility and malleability                                      -Tensile strength                             -Melting and boiling points

-Constituent bonds                       -Types of bonding                             -Intermolecular forces

Give an example of microscopic properties

A mixture is a combination of two or more substances in any proportions

-The components are not in a fixed ratio                                        -The components keep their own properties                                      -The components may be separated by physical means  

Heterogenous mixture and homogenous mixture

A homogenous mixture is a mixture with a uniform composition and all components are in the same state (that will remain constant for a period of time)

It means that the components cannot be distinguished from each other and the components are in the same state

What does the definition of a homogenous mean

-Cool drink concentrate                    -Air                                                -Alloys                                             

What are examples of a homogenous mixture

-Brass: mixture of copper and zinc                                                  -Steel: mixture of iron and carbon  -Bronze: mixture of copper and tin                                                    -Stainless steel: mixture of iron,chrome and nickel

Give examples of alloys and what they consist of

A heterogenous mixture is a mixture with a non-uniform composition. Particles can be distinguished.

It means that the constituent particles are not in the same state and are clearly distinguishable.

What does the definition of a heterogenous mixture mean

-Mud                                                 -Smoke                                            -Cool drink and ice cubes                 -The meat, vegetables and gravy in potjiekos 

what are examples of a heterogenous mixture

A pure substance is a substance composed of only one type of particles. They can be elements or compounds which are different elements bonded together by a chemical reaction.

An element is a pure substance consisting of only one type of atom that cannot be broken down into simpler substances.

A compound is a pure substance consisting of 2 or more types of items that are chemically bonded and can be broken down into simpler particles.

A mixture is a substance composed of different elements and/or compounds that can be separated mechanically.

Explain how particles can be broken down in a element

Particles can be broken down by chemical means

Explain how particles can be broken down in a compound

Particles can be separated by physical means 

Explain how particles can be broken down in a mixture

The smallest particle is an atom or a molecule of a diatomic element

What is the smallest particle in an element

The smallest particle is a molecule (covalent bonding) or an ion( ionic bonding)
