Elements, molecules, mixtures (homogeneous and heterogeneous)

There are two types of mixture

• Magnetic and separation

• Decantation and filtration

• Heterogeneous and homogeneous

• Heteregeous and evaporation

Filtration and evaporation are...

• A mixture of two substances.

• A homogeneous mixture.

• Methods to separate the components of mixtures.

• A physical combination.

If we dissolve salt in water and heat the water, it becomes a vapour and leaves the salt. This is called

• Decantation

• Evaporation

• Filtration

• Distillation

Matter existin three main states...

• Reversible, irreversible and volume

• Mass, density and volume

• Solid, liquid and gas.

• Physical, chemical and irreversible

The pure substances are classified in...

• Homogeneous and heterogeneous

• Element and compounds

• Pure and Impure

• Mixtures and compounds

This separation method is called...

• Magnetism

• Filtration

• Distillation

• Evaporation
