Homogeneous
What is Homogeneous?
A mixture so well mixed you cannot see the different parts
What is Solid?
Solids have a definite volume and definite shape.
The atoms are very close together and can only vibrate in one place.

What trait does heterogeneous have that homogeneous doesn't have?
You can see different parts in a heterogeneous mixture but you cannot see the different parts in a homogeneous mixture.
What is Liquid?
Liquids have definite volumes but no definite shapes. The atoms are further apart and are allowed to slide by each other.

All the separations
Sieving, Evaporation, Magnetism, Simple/Fractional distillation, Chromatography
What is the particle size of a solution?
0.01-1nm
What is Plasma?
No definite volume or shape and can float.
They are charged because they lost their electrons.
What do Beryllium and Nitrogen make?
Gas --> Solid
Deposition
Andrew mixed beer and water and his father got mad thus he told him to separate the beer and water. What kind of separation should Andrew use?
Fractional Distillation
What is a solvent made of?
Mostly Liquid
Why did Plasma lose its electron?
They are typically formed by heating and ionizing a gas, stripping electrons away from atoms, thereby enabling the positive and negative charges to move freely.
